I am mesmerized by our new robotic vacuum (2019)

    I bought a robotic vacuum more out of curiosity and to see if I should buy one as a gift for my parents. Just one of the cheapest models that still had good reviews.

    It turned out that all deficiencies of such a vacuum are offset by its basic function: it keeps the apartment clean each day, every day. Dirty corners? Weak suction? Small container? Somewhat noisy? Not too smart? Gets stuck sometimes? I need to clean hairs out of the rotating brush? I still have to mop the place? Pffft, none of this matters when the carpet and the kitchen are dust-free every day without me doing the vacuuming. If it misses a spot today, it will get it tomorrow. After a few runs the floor is indeed cleaner than it ever was, and stays that way. No rogue crumbs stuck to my feet before the cleanup day. Still managed to find something unpleasant on the floor? Just give the robot a bit of work right here. It's like SSDs after HDDs: you have to worry about having backups, but it'll be amazing in the meantime.

    Rather prophetically, the cheap production has shown itself when something got cooked in the electronic insides and the vac entered the eternity of ‘error 03’.

      > If it misses a spot today, it will get it tomorrow.

      One of the complaints about the smarter robot vacuums (like ones that map the house) is that they consistently miss the same spots every time. I think the dumb "bounce off the walls randomly" algorithm is actually the best one for this kind of product.

        One actual problem I had with a most basic Roomba(6xx) was it was banging a shelf in the room at exact same angle each run every day, which eventually toppled a thing on it and splayed water all around.

        I felt like writing a automobile recall notice that says “inappropriate X leading to Y after Z repeats” of which X seems pretty benign item like a wire sheath was just one step too thin or a strap was too tight by a notch.

        Damn those things are consistent and it’s extraordinary how powerful consistency is...

        • Intermernet 5 years ago
          The correct bug fix for this is to move random items in the house periodically. If it can't be random, then you can.
        • kumarvvr 5 years ago
          Perhaps some randomness can be part of the smarter ones algorithms.
        • raducu 5 years ago
          I don't like the cleaning I have to do before I let the robot loose -- pick up toys; I could vacuum much faster than the robot does and without heavy lifting of items in my crowded flat.

          But I usually don't vacuum, so overall I'm satisfied with my roborock.

          • bonniemuffin 5 years ago
            I love this feature! After a lifetime of throwing my socks on the floor, Roomba finally trained me to put them in the laundry hamper. I've learned to keep my floors tidy all the time, and my life is much better for it.
            • wpietri 5 years ago
              I like this feature, too! When I first got mine I had it set up to run only on certain days, as my small place doesn't need a lot of vacuuming. Then I discovered that the closer I got to the robot run, the tidier I was. So I wrote some code to make it run on random days, and that finally got me to stop trying to cheat.
              • Nursie 5 years ago
                Ha, yes. I haven't had a roomba for a few years, but it was always an adventure finding it on those days when it hadn't made it back to the dock.

                More than once I found it under my bed, a sock half swallowed in its intake.

                Poor little guy didn't survive the container voyage from Australia to the UK.

              • minitoar 5 years ago
                Same. I can no longer just schedule it to run unattended. First I must “prepare the house to be roomba’d”.
                • elliottkember 5 years ago
                  This is something I’ve come to appreciate about my roomba. It trains me to keep my floor tidy. I don’t have kids, though, so it’s doable. Little guy sure loves to eat cables.
                • aasasd 5 years ago
                  I don't know your particular setup, of course—but personally I quickly stopped worrying that the floor is occupied by something—unless it's small enough to be gobbled by the vac. The reason being, even if it's there today, I'll probably move it tomorrow or in a few days, and the robot will clean the spot after that. I guess someone could even split out a corner for toys with those infrared divisors, and occasionally let the robot loose in there manually.

                  Might be an application for more advanced computer vision in vacuums—to figure out which things are not to be sucked up. Though it smells of generic AI.

                  • shadyMrPatch 5 years ago
                    My girlfriend left a cable hanging out of the front of the playstation, I came home to find the robovac hanging vertically halfway to the shelf having consumed the usb cable and started climbing up.

                      A photo of that would probably be mildly popular
                    • aasasd 5 years ago
                      By the way, in regard to removing larger items (as opposed to small ones that could be eaten by the vac), I'd also like to note that the floor doesn't really get dusty under those items. Because, of course, dust collects on the items instead. So there's no even particular reason to shuffle things around if the robot can find its way around them—and judging by my cat's relationship with the vac, the latter can go around plenty of things that are getting in its way.

                        I think my family is unfortunately going to have to wait for some sort of robot with a snow shovel attachment and a big bucket to go dump everything in.

                        We used to have a roomba, first edition, before kids, but it got broken after a year, the first kid came and we have not been clean since.

                        • danielheath 5 years ago
                          Yeah - pre-kids I used the robot vacuum regularly.

                          Post-kids, it takes 10 minutes to tidy the floor and 5 to vacuum it myself (and I do a better job), so it's not as much use.

                        • trianglem 5 years ago
                          The killer feature for me would be if it could empty its dust container in a secondary location so I didn’t have to do for a month.

                        A good way to explore the algorithms of the robot is to set it out to run in the night. At the entrance of the room, set a high obstruction. Set up a tripod. Take long exposure photos every minute or so. Then turn on the lights/wait till day time. Take another photo. Overlay the photos in an editor program. Spot the missing areas.

                        EDIT: here are some examples by other people: https://spectrum.ieee.org/automaton/robotics/home-robots/lon...

                        And here are some resources if you have a Xiaomi robot vacuum cleaner (also sold as RoboRock) https://github.com/dgiese/dustcloud

                          I'm assuming you forgot to mention the light on the robot in the dark.

                          In order to get the progression of the run, you could have an RGB LED sweeping through a color scale during the run.

                          • amelius 5 years ago
                            And make sure that any LED on the robot is visible from the direction of the camera regardless of the orientation of the robot ;)

                                  I do not trust Eufy brand anymore. We had a Eufy RoboVac and within its warranty period, battery went bust. When attached to its station, it gave some sound errors which is apparently tied to its battery. I contacted support several times, reminded their obligation for warranty period but they did nothing. They asked me to find a "certified technician" to get a report such that this malfunction was present when I made the purchase. I asked what do they want as "certified technician" and where can I get one. They stopped replying. This took a week.

                                  Fortunately I bought the item from Amazon. I issued a dispute and within minutes they created a return label and issued a refund.

                                  I now have a Roomba. I'm pretty happy so far.

                                    iRobot is a great company. They'll sell you parts to repair your robot. The take refurbished units and sell them for educational purposes [https://www.irobot.com/about-irobot/stem/create-2], with a fully open and documented platform [https://www.irobot.lv/uploaded_files/File/iRobot_Roomba_500_...]. It's so obviously a company that started as somebody's grad school project, and remains so to this day, and I mean that in the best possible way.

                                    As usual, a bunch of ripoff Chinese competitors will sell you a cheaper piece of shit that you'll find yourself throwing away in three years. Resist the temptation.

                                      Yeah. I got a squeaky wheel on my Roomba 960, sent an email to customer services, they just sent me a whole new wheel module with instructions on how to replace it. Really really great service. And it looks like pretty much all parts of the robot can be bought and replaced separately.

                                        Note: Create 2 is just low-end 6xx missing a few parts. If you're going to buy it just for robotics experiments, just buy the cheapest models that looks exactly the same(not E5, 690 or 800), or older(OG, 400, 500). Costs the same but when you're bored they vacuum your floors!

                                          Another company is Bobsweep (Canadian company) that sells you parts too and their machines are easy to repair.

                                          In my opinion, the iRobot support and parts availability are worth the premium. Our 2013 model 650 is still running great. All we’ve had to do is periodically replace worn out brushes and spinners and at some point we replaced the main battery. This is all easily done with a screwdriver.
                                          • bonniemuffin 5 years ago
                                            Totally agree. I just checked my order history: I bought my current Roomba 650 in May 2014, so it's been running 4-5 days a week for almost 6 years straight with various simple part replacements. Really great little product, and excellent customer support and user community.

                                            At one point the tread wore out on the wheels, so it was struggling to get over the threshold into different rooms. Rather than buy a whole new set of wheels, I found a blog saying that Kirby 301291 vacuum cleaner belts just happen to perfectly fit on roomba wheels and work as replacement treads. Now it's been happily rolling around on vacuum belts for the past year or more.

                                              I absolutely agree. I got a broken 650 from my sister, fixed it with a cheap easily available part, and it has worked beautifully for the last three years.

                                              It is also a joy to maintain and was obviously designed by people who care about maintenance being reasonable.

                                                Same here with a 650 I got in 2016. It runs daily, and all I've ever had to do with it is replace the brushes/spinners twice.

                                                I find this a little surprising because, Anker, Eufy's parent company, has a good reputation from my perspective.

                                                  Anker has utterly lost my faith - all 3 Anker QI charging pads failed within months, and the USB-C to A cables I bought more recently don't want to stay connected on the data pins.

                                                  The battery on my RoboVac 11 went bust right out of the warranty period even if it probably had ~15 recharge cycles on it. Bought a replacement (~30E) and the vacuum is happily chugging along doing a good job. This being said I assume Eufy is saving money on that front so I'm not entirely sure my next purchase will be from them.

                                                    so I take it the battery is user replacable? That's my worry with most of these electronics, the product can be fine, but if the battery is welded in place, then it becomes a huge PITA to replace.

                                                  My anecdote: our Eufy has been working great for just under a year, now. We have a lab that sheds bucket-loads off hair, and it is generally able to keep things clean. The only real problem is that I was a bit over aggressive cleaning the roller brush, and removed some padding, and now I need to get a new one.

                                                    It runs Ubuntu, you can root it. And even get spotify running on it.

                                                      Some might ask why you'd want Spotify on your vacuum? I would have it play Dolly Parton's "(Working) 9 to 5" on loop whenever it's running. I feel like that would be hilarious forever. Other suggestions welcome.

                                                            The algorithm of going straight until you hit a wall, and then turning a (constant) angle has some really cool properties -- some angles/starting positions will eventually let you cover the entire floor, while others will produce beautiful repeating patterns [1].

                                                            One key insight for visualizing "hitting a wall and then turning" is that you can pretend that the walls in your room are covered with mirrors that you can walk through. Hitting the wall and bouncing at an angle is equivalent to approaching the mirror at your angle, and then continuing straight through it into the mirrored side. You can verify this in your bathroom mirror by bouncing your finger off it, vs. pretending it goes straight through: in both cases, which side of the bathroom does it bounce toward?

                                                            After a finite distance of continuing straight through mirror-walls, do you end up in your original location? I.e. can you see the back of your head in the room of mirrors? If so, then you're on a periodic path, and you're not going to cover the entire floor.

                                                            [1] https://arxiv.org/pdf/1810.11310.pdf

                                                              Interesting! I wonder if it matters for this case... the walls of the room aren't going to be exactly parallel (or may be a trapezoid, pentagon, or worse), the robot's wheels are going to slip somewhat on each turn so the angle turned won't always be the same, etc. Stupid real world :-)

                                                              I too bought a robotic vacuum out of curiosity (high end iRobot) and found the algorithm to be completely inadequate both in it's mapping and it's ability to adequately cover the area that it was supposed to clean. Additionally it left random patterns in the carpet that could only be described as a drunk toddler vacuuming... in other words, it didn't look clean. It took more than 3 days to map the three rooms that it was supposed to clean, getting stuck away from it's base unable to return because it's charge ran out. It would also get stuck under my bed. I'm not certain how it's possible that it could have done a worse job. I waited for years to enter the robot vacuum market and can state unequivocally that waiting 9 generations wasn't enough of a wait.

                                                                I had a Roomba sometime after 2006 and it was dumb but not in a bad way. It had a drop sensor, bump sensor, and tire sensors. It would primarily move in a switch back overlapping pattern and had a couple different fallback patterns that would kick in if the bump sensor triggered to frequently. It didn't necessarily hit 100% of space in the first try but it could autodock and recharge, and had a couple invisible walls to cordon it off.

                                                                It got stuck occasionally and needed to be rescued but once you knew what it got stuck on you could clean up, as you would with normal vacuuming, and it would be mostly fine.

                                                                The newer robot vacuums have a lot more tech but don't seem to have improved upon the basic functionality much. They still get stuck a lot, have trouble with deep pile carpet, and don't get everything.

                                                                  • asdff 5 years ago

We have a longhair cat and I run it around the apartment every couple days, filling entirely with cat hair every time from one cat in a hardwood floor apartment. It's been great.
                                                                    • remmargorp64 5 years ago

                                                                      I honestly have no idea how Roomba is still in business

                                                                      • neodymiumphish 5 years ago

I had the original RoboRock and it worked really well. We replaced the battery and gave it to my wife's grandmother, then bought the S5 thinking the mop feature would be in some way useful, but I'm still happy with how well the S5 tracks its brush/filter lifespan and the software upgrades!
                                                                    • gambiting 5 years ago

It takes longer than the 2 hour battery life to clean it all, but that's not a problem - it goes back to the base, empties its own bin, recharges, and then continues where it left off. It's truly amazing in terms of how well the mapping deals with that house, it shouldn't be that good.
                                                                      • gbrown 5 years ago

                                                                        • lscotte 5 years ago

The way I look at it - it's as if the Roomba was designed by students that just took a class on chaos theory and watched Jurassic Park, where the Neato was designed by actual engineers. The Roomba is fun to watch bounce around randomly. The Neato just vacuums the carpet in a logical algorithm, the same way a human would, more or less.
                                                                          • remmargorp64 5 years ago

                                                                            • numpad0 5 years ago

But anecdotally with the state of the floor as the metric, 622 seems to do better than XV-11 despite being horribly dumb.
                                                                          • systemtest 5 years ago

The downsides included aggressively bumping into my thin-legged chairs, moving them for a couple of centimeters before coming to a stop. Not being able to vacuum black carpet. Not being able to vacuum dark rooms, so I either have to leave all the lights on when I leave or leave the curtains open (thus letting in cold). It broke the delicate moulding at the base of the radiators by ramming into it. It would distribute the coconut fibers of the doormat all over the house. It would go under the bed but would not be able to get out. And I had to enable 2.4Ghz WiFi after all these years. Which was troublesome because my iPhone was connected to the 5Ghz network and it tries to copy your iPhone network to the Roomba.

                                                                            Returned it. Doing a 15 minute vacuum every Saturday morning is easier for me than to deal with all this, and it keeps the house tidy during the week.

I'm not even in the US, but DDG'ing the "Eufy RoboVac 30" brings me straight to the manufacturer's website, where it's even $40 cheaper. Why give "Lord Bezos" a piece of the cake, when he doesn't even need to have one?

                                                                              Maybe it wasn't so at the time of writing, but I have a weird feeling it's en vogue to claim to be against Amazon, but to then find some half-assed reason as to why they're still the "only sensible" choice, and so it's all good. WTF? Are these Amazon-financed articles?

                                                                                - Will any of those pages be broken, forcing me to start over?

I'm not even so impatient that I need the "two day thing" (I usually pick a later date for a $1 Amazon digital credit anyway), but, when? There are nearly never estimates, and about half the remaining MIGHT send a tracking number later.

                                                                                Other things crop up, but basically there's countless little things that can go wrong and you if you pick Amazon they _all_ go away.

I'd rather deal with all of the other problems (which aren't really problems as I'm not liable anyway), than risking getting a counterfeit product from Amazon.

Subscription lists in the EU have been greatly reduced by GDPR. Some still offend this, granted, but they are occuring less and less.

The technical security details are legit concerns in my opinion, too. OTOH, sticking to one merchant brings with it the risks of mono-cultures.

I feel they grant more autonomy to the merchant, which I believe to be actually better for the customer in the long-run. Amazon feels closer to the customer, but such a customer strategy runs the risk of a bait-and-switch to the disadvantage of the customer, once their monopoly solidifies.

And all I'd need to do is join the Amazon ecosystem and I'd probably even be one of the customers that Amazon would make a net loss on, to my gain!

The times I'd need Amazon I can usually find a similarly priced competitor, where buying is more of a breeze and bliss than Amazon, having to work through the special conditions of coupons, terms, etc.

                                                                                            There was only one case in my experience, in 2013 or -14, where Amazon was the "only choice", when I "want-needed" a cheap China-made USB microscope, and Amazon had it, but not a single merchant on eBay. The device was quite fresh on the market, and about half a year later was also available on eBay. I waited.

                                                                                            • 0xffff2 5 years ago

                                                                                                  It's a legit strategy, it's just that one needs to keep in mind to second-guess everything the author says, since it could be a paid ad. Something, something along the lines of commercial and independent reviewers. I guess it's a never-ending war that must be fought.

I can do a decent vac in about 15 minutes. 30 minutes if I do under the bed. 2. When I do the "big vac", I have to move 6 dining room chairs. Then shift the table a few inches. Zoom. Shift if back. Same goes for some other legged furniture. 3. I also do the windowsills. No bot can do this. 4. Don't you end up with little arched dust patterns in every corner of every room? How does a round vacuum do this? Seriously! This is the deal-breaker for me unless they have some little robot-wars-style dust-brush that shoots out to get into the 90 degree angles.

                                                                                                  All that said, I really really want one!

                                                                                                    1) It runs around our flat which I think we could vacuum well in about 15-20 minutes, perhaps similar to yours in size.

                                                                                                    2) The vacuum happily bumbles around under our table and chairs and it seems to do a pretty good job. If we want it to clean where the chairlegs are, we just move the chairs against the wall the night before and move them back the following evening when we get back from work.

                                                                                                    3) I feel like this is a cheap shot: it doesn't clean bathtubs or toilet bowls either (and like windowsills, it doesn't advertise to clean those, either).

                                                                                                    4) No. It may be round, but it has two rotating brushes placed towards the front which get dust and crumbs out of corners, but the brush/vacuum portion itself does not reach right to the edges of the machine, so you're unlikely to get deep cleaning on the edges of carpets.

                                                                                                    Overall I'm very impressed with it: it consistently comes back with a lot of dust and crumbs in its bin (we run it Mon, Wed, Fri), replacement parts (e.g. brushes) are cheap from the usual suspects in China, the edge cleaning is more intelligent than discussed by the linked article, and the floor under our sofa (a heavy 3-seater) has never been so consistently dust-free.

                                                                                                    • Tade0 5 years ago

Thus, we clean together once a week: it does the vacuuming, and I clean the bathroom, kitchen etc and help it go where it wants.

                                                                                                        This kinda works, but I wonder if there are models specifically with higher clearing for getting over bigger obstacles?

I often run the roomba as I clean other stuff or do the dishes when I prepare for a visitor. If you run it daily or every other day, the first couple of days it's full of dust and hair, then less and less. I view this as evidence that it's needed.

                                                                                                            I don't dare keep it on a schedule nowadays, because I have kids who leave stuff on the floor everywhere, including charging cables for phones that can get tangled up in the roomba. What I usually do is a quick check under the couch and tv bench, then start it manually when I leave for work.

                                                                                                          • drakonka 5 years ago

The Roomba does not replace the Dyson, but in terms of floors the Dyson is mostly reserved for spot-cleaning. The S9 gets all the edges, and goes around each table and chair leg (though I prefer to put the chairs up on the table for easier reach).

                                                                                                            The only thing I hate is that it gets stuff trapped in there so easily. It is meant to have some sort of anti-cord-catching technology, but unless I am very careful I will find it eating a charger or a cat toy or something. It also takes longer than my handheld vacuum, but I don't mind that - often I just quickly pick things up before I run out to the store and let it run as I leave, and then come home to a vacuumed apartment.

                                                                                                            My cats also prefer the Roomba even though the noise is comparable. They hide from the Dyson, but couldn't give a crap about the robot running around.

                                                                                                            • Yizahi 5 years ago

Even through weekly cleaning with a powerful "normal" vacuum cleaner won't help with everyday hair and dust accumulation. And personally I'm often too lazy even for a once per week cleaning. This thing (I have Roomba 960) collects most of the dirt in the most visible places. It really makes a difference. And corners don't matter in a big picture where every furniture item collects a ton of dust in hard to reach places.

                                                                                                                We've the exact same model as the article, bought on a sale last year for ~£180, and have been incredibly satisfied. The difference between a once a week/fortnight deeper clean and having it run over every day (before we get up!) has been incredibly obvious. It has also added an... incentive to avoid floor clutter.

It takes me 1-2 minutes to pick up stray socks and usb cords and start the vacuum right before I walk out the door for work. The things it doesn't do can be dealt with with a broom and duster, and that ends up being very infrequent.

When we need to clean the upstairs bedrooms I can just leave it there, press start, and it does its thing and we can go and have dinner in the meantime. Yes, you still have to hoover manually from time to time. No, it doesn't do corners very well. But the fact that it can automatically clean at least one level of your house every single day is just incredible.

                                                                                                                            15 years ago, I had one of the first robot lawnmovers (Husqvarna) and did exactly the same thing: Watched it for hours, observing how it worked.

                                                                                                                            Back then, it seems it was programmed with instructions:

                                                                                                                            - Go! If you hit an edge, rotate in a random direction and ... Go! - If crossing the base-wire (a buried wire leading to the base station) while battery level < 40%, follow it and charge.

                                                                                                                            • alfiedotwtf 5 years ago

There’s something soothing with just starting at the print head while the plastic oozes out and creates something tangible. It’s Star Trek’s replicator v0.00001. After a while, you realise you’ve been staring at it for 45 minutes.

                                                                                                                                I'm confused how Amazon is relevant here. This product is available from many online retailers under $200.

                                                                                                                                If you want to quit Amazon... then maybe try even a little?

Our pup dropped a load in our bedroom and the Roomba smeared it 5 feet across the carpet. Some bits were stuck to the front bumper, so the Roomba left little poo polka dots on our baseboards.

Some pet owners have been recommending getting one as a way to get rid of pet hair if/when I got a puppy. This is one of the best examples of the unintended consequences. I guess house-training is a must.

                                                                                                                                    - It has infrared proximity sensors spread around the bumper which allow it to slow down before hitting a wall or other large flat surface, avoid it entirely (for example to turn around and shoot off in another direction), or do quite precise edge cleaning without relying on the bumper. This works best on walls or skirting boards.

                                                                                                                                    - The base station has an infrared beacon which the robot uses to find id. Furthermore, the robot can judge whether it is on or off-axis relative to the base station (i.e. whether it is lined up straight or not). The robot doesn't just dive in from any angle: it tries to line up first.

                                                                                                                                    - It has some level of stall detection for its motors: if the brushes or wheels get stuck on something, it will stop. The internet-connected versions of these vacuums will send out a notification when this happens.

                                                                                                                                    • JoBrad 5 years ago

Its very informative. Not necessary to wait and see what a brand will do; just find a video and watch it in fast-time.

                                                                                                                                        I have a Shark IQ which some videos rate as the best in the middle class. We have 1200sqft to cover and it can do about half that on a charge, methodically.

                                                                                                                                        But it often gets stuck behind the AV center, or behind the piano, or wedged under my wife's chair or a certain cabinet baseboard in the bathroom. At least once a week. And with nobody home, the voice alert calling for help is pointless (scheduled to run when nobody is home).

                                                                                                                                        So it just runs its batteries down waiting. If it could do one more thing better, I would say go into low-power when stuck?

                                                                                                                                        Anyway we like it, gave it a name ("Puck") and each day check if Puck 'made it home'. If not its a pleasant job walking around to find where Puck got stuck. Not a bad purchase at all, considering the always-clean floors(!) and the entertainment value to boot.

                                                                                                                                        • chasd00 5 years ago

I was skeptical but every time it runs the little dustbin is completely full. I figure if it didn't run, all that dirt, dust, pet hair would still be on the floor. I wonder if all the roombas gossip about how dirty our floors are to other roombas over wifi..

                                                                                                                                              You have to into the account the respective strengths and weaknesses of humans and robots.

                                                                                                                                              I can easily best a robot at sensing the layout of my living room, but a robot can easily best me at perseverance.

                                                                                                                                                I got a robo-vac, but ultimately stopped using it because of chairs and children. I had to clean up in order to run it at all, and it would get stuck under the chairs and not be able to get out. (I guess exactly the wrong sizing.)

                                                                                                                                                I mainly got it because my wife and I have a dust-mite allergy and cleaning the floor with water or HEPA vacuum can help. We've replaced it with a much more expensive (and totally manual) hizero[1] wet vacuum, and it's great. Also, we have tile floors so wet always cleans better than a vacuum (and wet pads need to be cleaned/replaced way too often on a robo-vacuum).

                                                                                                                                                [1] https://www.youtube.com/watch?v=og8lhk3oZe8

I bet if you just watched a simulation of the robot (which could probably even run in the browser), you wouldn't be all that impressed. The fact that it has motors and that it moves makes it cool.

I just stick my hands in the trash bin and open it there. For the upright dyson vacuum which I use on higher pile carpet that clogs the robot, I have to take the canister to the large trash can outside because dust gets absolutely everywhere.

It self-empties with a blower each time it docks. Empty that over the bin in the garage once a month (just pick it up like a suitcase with the handle, carry it out, press the button on the side and the bottom trapdoor opens and whoosh! all the dust outside in the bin).

I use a bag free (manual) vacuum and I even though I can manage it without water and not create too much airborne dust, if you just spray water it slightly it will stick to eachother and become big balls.

I have tried to understand how my basic Roomba works as well. One simple algorithm could be that it is simply storing the path it travels randomly like a criss-cross, zig-zag path and ends up filling a imaginary polygon with those zig-zag movement. That's probably the reason it does not get stuck doing the same part of a room again and again.

                                                                                                                                                                  Make A cleaning schedule with different frequencies for different tasks. For humans you have to limit complexity, the robot cant get enough of it.

                                                                                                                                                                  The trick is to do a great job with the least runtime and perfect timing.

                                                                                                                                                                  1 (Highest frequency): The visible areas when walking from the front door to the seat where your guests will sit. The entire house can be either 1) a complete mess, it will still look clean. Or 2) the entire house can be supper clean it still wont look clean.

                                                                                                                                                                  Some cameras would be nifty here.

                                                                                                                                                                  1.1: edges for 1

                                                                                                                                                                  2: Same as 1 for all frequently used paths in the house except those covered by 1. Could split this up into levels of frequency.

                                                                                                                                                                  2.1: edges for 2

                                                                                                                                                                  3rd: All open surfaces not covered by 1 and 2.

                                                                                                                                                                  3.1: all edges not covered by 1.1 and 2.1

                                                                                                                                                                  The edges are done roughly every 4th round.

                                                                                                                                                                  The 1st it can do multiple times per day depending on traffic. (1 times is a good minimum) It could by a dynamic number based on motion sensors. Timing is everything, if the room is empty it can do its thing for 2-3 minutes (quit if someone walks in) Nr 2 is done half to 1/3 as frequent as 1. Nr 3 is done half to 1/3 as frequent as 2.

                                                                                                                                                                  I've used the above system for years and it continues to amaze me how quick one can execute the routine and how clean everything looks. Nr 1 sometimes takes no more than a gaze around the room.

                                                                                                                                                                  Without such system one just does "everything" every time which is a lot more work than it seems. (enough work to cut the same corners every time) The result also looks really inferior.

                                                                                                                                                                  • samsolomon 5 years ago

It's funny because functionally they are worse than a cordless sick or full-size vacuum in almost every way. However being able to turn it on before I head for work everyday makes a giant difference.

                                                                                                                                                                    One thing I am skeptical of is robot vacuums that connect to the internet. Some of the higher end Roombas do that and I'm skeptical that it makes them more efficient. Wrote some more about it here:

                                                                                                                                                                    https://productdork.com/t/whats-the-best-robot-vacuum-cleane...

                                                                                                                                                                    The good news is that the Eufy's seem to work fine without any internet connectivity. I've got the Eufy RoboVac 11S and would highly recommend it. Unlike my previous Roomba, it doesn't speed up before bumping into things—it mostly avoids it. Also, it is significantly quieter.

                                                                                                                                                                      The big complaint I always hear is "yeah but the pattern is random, it doesn't clean the whole floor evenly"

                                                                                                                                                                      That is technically true, but the roomba cleans the floor for an hour, randomly, every day. This is a tremendous amount of cleaning. It pulls probably a pound of dirt off the floor every week, maybe more. Being able to have the floor cleaned - even randomly - for an hour, every day, makes a tremendous difference.

                                                                                                                                                                      It might not get the spilled cat food for 2-3 days, but on day 4 it will get it. If you're only vacuuming once a week that is probably faster than a human would do it. It also vacuums all the weird spots, like under the sink in the bathroom, that you forget to check every week.

                                                                                                                                                                      It also trains you to not leave stray socks, cell phone charging cables etc on the floor. Which is nice if you're not super super tidy.

                                                                                                                                                                      • roland35 5 years ago

You can get pretty far with random turns with some edge following.

                                                                                                                                                                        One thing that can help a lot is gps (or other absolute position). This can definitely help make sure your robot can make roughly the correct turn to get in those nooks.

Just hit go before leaving and you’re set.

                                                                                                                                                                          Now I’m curious about the lawn ones. Anyone have any experience to share?

One of the nuances most simulators do not fully grasp is that there are path rectifiers that emerge from physical interactions. Examples are collisions with walls where even though the robot comes in at a range of different angles, due to momentum and friction variance is lost and it leaves in a more narrow set of angles. Another example is grooved surfaces such as you find on wooden or tiled floors where slight angles to the groove are passively adjusted to the groove.

                                                                                                                                                                            I worked extensively on small robotic vehicles in the 80's and 90's. My undergrad thesis was on a robotic simulator.

                                                                                                                                                                            • chiph 5 years ago

What impressed me was how strong the suction was. My initial thoughts were "How can something that small ever pick up as much dirt as my regular vacuum?" But it actually does better than the upright - it picks up far more dirt/cat-hair, even when the upright is on a fresh filter. Which is important with a long-haired cat - I get cat-hair tumbleweeds on the stairs. I sweep them manually down to the next floor, and hit the start button and leave for work. I return to a freshly vacuumed floor.

It still works great and has freed up 30min to an hour of time per day she spent cleaning up the floor (they're Korean and spend a great deal of time doing activities on the floor so floor cleanliness is very important).

                                                                                                                                                                                More importantly, her legs and back aren't doing so well these days and it's eliminated a painful and difficult daily task for her. She loves it almost as much as a pet. Just set it up and forget it for the next hour and the floor is mopped! The biggest problem it has is getting hung-up on her grandkids toys.

                                                                                                                                                                                    It was an interesting exercise, and if our pet-load was a little lighter (I'd hate to see it get caught in Macaw Poop) I'd consider doing it again.

                                                                                                                                                                                    Maybe a mop for the trailer?

However, my house is not very flat. It has two main floors, but several rooms are offset from the main floors by about a foot or two (who knows why). Is it possible to put a small ramp on the stairs and tell the vacuums how to navigate it?

I'm still amazed at how much dirt the vacuum picks up. 15 min of manual vacuuming is nothing compared to 2 continuous hours. Now that I have a dog, for $200, it's a no-brainer. When I come home it's a noticeable difference.

First it traces the boundraries of the room or 10ftx10ft if it can't find a wall within that distance and then follows a rectangular path adjusting for any obstacles it finds in its path.

Watching the 2D LiDAR work while the robot does the path planning is absolutely fascinating to me for a machine that is less than $400.

Totally fascinating - more than once I even got it out to show to people visiting! n:)

                                                                                                                                                                                                                        The Neato ones are a bit more methodical - they have a simple time-of-flight rotating laser sensor that does some SLAM-style stuff to map out the room which means it can do long continuous back-and-forth paths across the room (random image I found that explains it nicely: https://www.generationrobots.com/img/cms/Navigation-Algorith...) It has a charging base thing - it has a special pattern of stripes (kinda like a barcode I guess) behind a human-opaque panel that it uses to locate the charger.

                                                                                                                                                                                                                        While it was nice to just set the thing off and leave it to do its thing, it is not without problems though:

                                                                                                                                                                                                                        - it would very happily suck-up and chew cables or errant socks etc, and/or push low stuff around in front of it (e.g shoes). You had to spend time picking up phone charging cables and shoes etc before starting.

                                                                                                                                                                                                                        - it was not very accurate when it came to working around slanted chair/table legs (since its laser beam would only pick a point approx 5cm off of the ground, it would often hit the lower part of the leg that was in its path but that it could not see)

                                                                                                                                                                                                                        - it would often get stuck "under" things since there was about 1.5cm of extra height above the laser, and it feels like a lot of IKEA furniture is all just high enough for it to drive under and get wedged because it could not see it.

                                                                                                                                                                                                                        - it would sometimes get stuck in situations where there was a very tight space between two things (e.g. dining chair and a wall)but where in theory it was wide enough for it to drive down - it would end up trying to reverse out, but actually managing to reverse into the wall and jack its self up so the wheels lost traction.

                                                                                                                                                                                                                        - it does not know if it has "missed" something or done a good job, so often stubborn bits of fluff don't get picked up.

                                                                                                                                                                                                                        We've now had to retire ours because we got new carpets and it seems to get stuck a lot on the new carpet that is a bit thicker, often doing wheel spins for 30 seconds at a time. This seems to really confuse the SLAM algo since after it regains traction it ends up just driving straight into walls and stuff, despite having a laser sensor to tell it there was a wall there ... I guess it used some sort of encoding from its wheels as input too (perhaps as a effort to ignore "unexpected" laser returns - e.g. perhaps intended to ignore people pets when it has already mapped a room?)

                                                                                                                                                                                                                        We've replaced it with a dyson cordless stick vacuum thing with a wall-charger-dock thing. It doesn't take that much longer to do it by hand when you factor in the prep-time (picking up cables, moving dining chairs away from the table, moving things far away out from the wall etc etc), rescuing stuck robot time, or manual pick-ups of things it missed required afterwards, and then moving all of your chairs etc back into position. It is also nice to not have to bend down so much to move the robot one around, or empty its dustbin.

                                                                                                                                                                                                                        • weeboid 5 years ago

                                                                                                                                                                                                                            We learn it’s „impulsive“ for her to make spending decisions (for him it would have been „decisive“, probably, given the good opportunity and how quick he is to think on his feet). He even moans about being „incapable of being upset“, as if it would be entirely normal, nay expected, to be upset about one‘s spouse making a sub-$200 spending decision.

                                                                                                                                                                                                                            Then he decides to „keep her“, as if it’s entirely his choice.

                                                                                                                                                                                                                            Yes, sure, somewhat outdated role models by themselves are somewhat benign, and probably too widespread to really get upset about. But this just stood out for me, somehow. Try reading it with reversed roles if you did not notice.

Relationships are not formal, both me and my wife say things to each other which might look "off" without context, but obviously are absolutely fine. You read about a slice of someone's life and try to find issues with what you're reading, you're always going to find them.

Sounds like a really boring world, loosen up a bit.

As people tend to notice after middle school, life can be enjoyed without any out-group being made the subject of tired stereotypes.
