A watched bot misses the spot... so many times I see it running and it JUST missed a piece of lint, over and over... and then I come back 15 minutes later and it's gone! Lots of negative reviews from people who seem to have not understood that this is a random motion robot. Keeping your expectations in line and realizing that even with a random pattern the whole house will eventually be covered every few days and this is an amazing little helper.I actually wanted a "dumb" robot because I didn't want an internet connected device because I care about my network security, and many consumer grade IOT devices have very poor security.I bought two very similar vacuums, one for downstairs and one for upstairs. We have very dark laminate flooring downstairs and it felt like even if I vacuumed regularly there'd still be stuff showing up shortly after I completed my cleaning. I'd do a whole house vacuum every week, but it still felt like I couldn't keep up, so I initially bought this one (the 11S+) for the downstairs laminate. I loved it so much that I bought an 11S Max for upstairs just a short time later.Since the 11S Max is so similar, I'll combine details from both in this review as they're relevant here too.For context, this is in a household with two long-haired adults, no kids, no pets.Downstairs on laminate and tile flooring with only an area rug and fairly basic furniture the device has worked perfectly. It got stuck once on day two in a corner where I had some chairs stacked up and gained the nickname "Waldo"... "Wall-e, the garbage collecting robot... got stuck... where is he? Where's Waldo?!", but hasn't gotten stuck anywhere since and always finds its way home. Every day at lunchtime I come downstairs from my home office and empty the bin and I'm shocked by how much stuff is in it, wondering how I ever lived in such dirty conditions! hahaAfter deciding that this was the best thing ever I bought another for upstairs on the carpeted floors. Things are a bit different there. It seems that every single room upstairs has an obstacle that it doesn't like, and I've had to do a LOT more robot-proofing. In the master bedroom it found its way into the walk-in closet and got tangled on a shirt that had a long string-like fringe and got stuck. In the master bedroom it gets up on the legs of the drying rack and makes a LOT of noise going over them, repeatedly. In the hall guest bedroom it got stuck under the bed that had JUST enough clearance for it to get under, but not get back out. In each of the home offices it gets hung up on the desk legs. In my home office it gets hung up on the legs of my music stand. One night it started beeping after going a touch too far over the edge of the stairs and not being able to back up. It's strange how the downstairs robot can go about its business daily w/o any problem, and the upstairs one has a problem in every single room. I'm gradually going around and finding ways to deal with the problem room by room (e.g. 3d printed bumpers on my desk legs), but it has been a bit more of a challenge. Like the downstairs robot it's SHOCKING how much crap the thing picks up every day, even after a deep vacuuming with our Sebo D4. Being as this one gets stuck so often it got the nickname Dodo. I still love it, and it keeps things cleaner, but does require a lot more babysitting. With time I expect it'll get better as I've been making and adding guards here and there to keep it away from areas where it shouldn't be.A note about the long hair mentioned before: On day 1 I tested the upstairs one before a deep-vacuuming, after about 2 weeks of not doing one and it got REALLY REALLY tangled with hair, but I did a deep vacuuming with the real vacuum and since then it has kept up enough that hair has not been a problem at all.Pros: Very quiet, good coverage (I seldom see a missed spot), picks up a crazy amount of stuff even when you think there's nothing for it to find, cheap maintenance parts, easy setup, no apps nor wifi connectivity to phone home and potentially compromise your home network.Cons: None if your house is robot-proof, some people may have zero problems, some might have a LOT of problems.

The media could not be loaded. Honestly I'm pretty picky with tech products, I don’t usually write glowing reviews - but this robot vacuum really earned it.The cleaning performance is excellent. It’s powerful, has multiple cleaning modes, and works great in a home with pets. Ever since I started using this robot, I’ve actually packed away my Dyson. I honestly wish we had one in the office too! The size and noise level are totally reasonable compared to similar products.What really sets it apart is the software experience. The map generation is incredibly fast and accurate - it easily recognizes rooms and obstacles, and sets up zones perfectly. The app is intuitive, user-friendly, and the prompts are clear. It works flawlessly across both my phones, an Android foldable and an iPhone. I’ve tried other brands before, but none felt this smooth or well-integrated.Hardware setup is also straightforward. Most parts are basically plug-and-play. The only tricky bit was the tray — it needs to be “clicked in” rather than just placed. I had to try a few times, and the app kept telling me it wasn’t properly installed. I eventually figured it out, but it would be great if the app could include a little animation or more detailed instructions when that error pops up.One moment that truly surprised me was when the robot managed to escape from a tangle of wires. One of the wheels was completely wrapped up, and I thought it would be stuck for sure. But it figured it out and kept going — clearly, the navigation and escape algorithms are top-tier.Frankly speaking, this robot has exceeded my expectations in both hardware and software. It has truly improved my day-to-day life. Highly recommended, worth the price!

Absolutely Disappointed - Two Defective Units in a Row!I am incredibly frustrated with my experience with the eufy E28 robot vacuum. I was initially excited to purchase this product, but it has been a complete letdown.My first eufy E28 unit arrived with a critical flaw: a broken membrane that is supposed to separate the clean and dirty water. Because of this defect, the water mixed, and the unit quickly started to emit a foul, stagnant ("abombao") smell, making it unusable.Believing this might have been an isolated incident – a stroke of bad luck – I returned the faulty unit and decided to give the eufy E28 another chance by ordering a second one. Unfortunately, my hope was misplaced. The second unit arrived with an entirely different, yet equally frustrating, problem. The right wheel is defective, causing the robot to stop randomly during its cleaning cycle, accompanied by an error message related to that wheel.To receive one defective product might be understandable, but to receive two brand new units, back-to-back, both with significant operational faults, is unacceptable. This indicates a serious lack of quality control on eufy's part.I will now be returning the second defective eufy E28 and will certainly not be trying a third. I cannot recommend this product to anyone based on my terrible experience. Save yourself the time, money, and frustration.
