eufy Robot Vacuum Omni S1 Pro with All-in-One Station, HydroJet Robot Vacuum and Mop Combo, Eco-Clean Ozone, 8000 Pa Suction, Obstacle Avoidance, Auto Mop Washing & Drying, Self-Emptying

I've had several robot vacuums and mops over the years. Neatos, Roborocks, Dreames (last one was a Dreame L20). This is the first one that actually seems to work as promised! I live in the country, have 2 dogs that shed A LOT (white German Shepherd; could make a new dog from his shedding every couple days). And 6 cats. Between the shedding and dirt tracked in, keeping the place decently clean is a big issue. We have a 1 1/2 story, about 2300 SF combined, nearly all hard surface. A couple small area rugs.Setup was pretty minimal. Snap the rotating brushes in place, remove the packaging, fill the water tanks and it's good to go. App setup and connectivity were great. I've had to mess with others a bit, they didn't always find and connect to the router on the first try-this did. It did a quick software download and update and was good to go. Also worth mentioning is that moving the base didn't mess up the mapping-it recognized the new location and went to work. (I moved it due to the loudness of the dust-bin emptying-mentioned below). The mapping cycle is very good-it's quick, just a quick pop in each room and it's done, took maybe 15 minutes.Every other vacuum I've tried has had a major design issue. They don't return to the base to empty the dust bin often enough (with our hair collection). The dust bin get packed full, of course can't pick up any longer and just pushes dirt around. The hair packs so hard it's like felt-and the base can't empty that. Ones I've had don't let you adjust that. This one does! I ordered ours after our Dreame crapped out-so it was nearly a week before it was here. I deliberately minimized cleaning-to give it a robust test. And it passed with flying colors! Set the "return to base to empty" to the lowest setting and let it go. Worked perfectly, returned to the base every time and emptied completely. Yes, the emptying cycle is a little loud-but to me that's an effect of a very strong suction in the base-it empties the dust bin and sucks out the filter very well. Something that can't be said for some brands.Mopping-just as everyone else says-works VERY well. My Dreame just smeared the dirt around (in spite of how much was in the dirty water reservoir every time!). Always left little muddy round tracks on the floor. The water tanks are much smaller than the Dreame, probably 1/3-1/2 the size. But it uses so much less water that it's not an issue-lasts just as long before you need to fill/empty the tanks. Another observation-the ozone generator seems to make a difference. The dirty water reservoir in the Dreame stunk bad, even emptied every 1-2 days. Really bad. This one, I don't notice a smell, or at least I haven't yet. VERY nice-though not a critical consideration. Only minor complaint is that the fill port on the clean water tank is small, you have to be careful filling, either hold it, or make sure it's sitting in your sink where the water stream hits the port. Would be nice if the whole top flipped up, like the dirty water tank. But a very small annoyance.Another observation vs the Dreame. It would very rarely dock properly-it would try to climb the ramp to dock and the wheels would spin, causing the vacuum to get tilted and miss the docking/charging ports. In addition, the mop pads left a lot of dirt and hair on the ramp, contributing to the above problem. Between this issue and the above mentioned dust bin issue, I couldn't let it run "auto" on the whole house. Had to do a room at a time and hope for the best. The Eufy has been perfect-vacuumed/mopped exactly where the mapping says it should, has never NOT completed a cycle and docks perfectly.I mentioned how the Dreame left dirt/hair on the ramp. This one doesn't seem to do that. The roller retracts up into the unit and doesn't drag it's way up the ramp. The only place that gets a little nasty is the little tray where the mop pad is cleaned-but it lifts out and is simple to clean. Very nice design-and far easier to clean that the mop-pad washing area of the Dreame or any others with rotating pads. The roller is a game changer.What else? Vacuuming is VERY good. My Dream left little trails of dirt at every threshold and transition to a carpet-this doesn't. And it doesn't leave little piles when it starts climbing the ramp on the the dock. This one also picks up kitty litter specs, unlike the Dreame. That would leave a lot-and when they got on the wet mob pads, that clay would turn to mud and smear. Not here-nothing but a clean, streak free floor left. You can really tell the difference barefoot-no little specs of dirt, no stickiness.Lets talk edge/corner cleaning. I find the vacuuming/dry cleaning to be the best I've seen on any vacuum. The dual brushes seem to help and also make the cleaning process quicker. Since the unit is more squared off, the brushes are mounted towards the corners and extend out well past the body of the unit. The round ones stick out past the diameter-but since they are towards the front of the unit, they don't really get past the OD path at the widest part. Not explaining that well, but hopefully you get the idea. Most of the round ones do a little shuffle along the edge (unless they have an extended brush arm) to try to address this-the Eufy can just truck along straight.A few other observations. The transparent clean water tank is nice-you can see the water level without opening a cover and removing the tank to check it. The tanks are mounted fairly high, so you don't have to bend over as much to change them. And as mentioned they are smaller-and LIGHTER. Another point-the dust bag on the Dreame and some others mount low on the unit. You have to pull off a panel on the front towards the floor. A bit of a pain. I usually had to get on the floor to slide the bag into place, you can't really see the mounting rails standing up. This one mounts vertically and is much more accessible, you can see the mounting rails from above. One thing I haven't checked out-the Dreame had a filter in the back of the compartment where the bag goes. A fair amount of dirt bypasses the bag and plugs that filter-it is a pain to clean-in part because you need to lay on the floor to see it. I need to check on the Eufy and see if it has a similar filter-will do so and update.So-complaints? Not much really. The above mentioned small fill port. It would be nice to have larger water tanks-but again, not a big deal concerning how little it uses-and the small tanks are lighter. Would be nice to mop all the way to the edge-my Dreame did have the mop extend. But then-it's cleaning was pretty marginal, so it didn't help much. This is a very fair tradeoff. This is also a simpler mechanism and should be less failure prone. Now-my one real complaint? The price of the Eufy cleaning solution. $26 on Amazon for that little bottle. Kind of ridiculous. But that's it. I'm an engineer, and having owned several robot vacuums/mops, am pretty critical of design and performance issues. This is by far the best I've used. I recommend it (but be sure to get it on sale for $1,000, don't pay the $1500). It's amazing how far the industry has come and how much better products have gotten in the last 10 years or so. I'm sure that will continue!

UPDATED to five stars. After the last firmware update, all the obstacle avoidance sensitivity issues have been fixed. Also, I contacted Eufy customer service to see if I could get a new front bumper and top cover as the robot scratched itself up badly trying to get under some furniture after I turned off the visual height detection. Eufy happily sent me replacement parts and even offered a small refund for the inconvenience. Parts arrived in a few days and the robot is all new again. Great customer service and support.Original review:Bought the S1 Pro to replace a trusty old Roomba i3+. Mopping is the star of the show as the S1 mops better than anything else out there, hands down. If you have lots of hard flooring, this is clearly the robovac to get. Carpet performance is... decent. Contrary to many reviewers, it IS able to pick up embedded dirt in carpet, but only if suction is set to Turbo or Max. The Standard setting (and thus quieter operation) leaves behind noticeable debris and Quiet mode doesn't do much at all on carpets. Carpet performance was one area where the Roomba i3 was much better than the S1, I suspect the Roomba dual roller design vs. the single roller on the S1 is the differentiating factor. I tried both the regular S1 and Pro versions and the S1 Pro is definitely worth the extra $200 for the better navigation and obstacle avoidance and clean water ozone generator. The ozone generator keeps the dirty water tank from smelling funky and keeps the internals of the robot cleaner in between maintenance intervals. With regards to navigation, where the regular S1 will occasionally bump into things or back up into furniture, the S1 Pro navigates without scuffing up any furniture or baseboards. And where the S1 may occasionally run over a small obstacle, the S1 Pro will detect and avoid literally any sized obstacle in front of it. This is a game changer for folks who have pets and want to run the S1 Pro unattended. However, the drawback to having such good obstacle avoidance is that the S1 Pro is very sensitive to changes in floor patterns, where it'll avoid a highly patterned rug because it thinks it's an obstacle, or will not go under furniture with small height clearances because it thinks it'll get stuck. You can turn down the height sensitivity, but then it'll happily wedge itself into other places it clearly can't fit, resulting in scratching the top cover and bumper. And you can turn down the obstacle avoidance sensitivity, but then it'll run over weight scales or other low profile items instead of avoiding them. It's kind of an all or nothing approach. It would be nice if Eufy gave us a middle ground sensitivity setting. However, if you keep all that in mind and set your home up right (avoid using highly patterned rugs and use furniture risers to allow for plenty of height clearance), then the S1 Pro is an excellent robovac.
