This eufy change everything, the first time I used it and basically everytime, the dirty water bin is black with dirt. Yet the mop roller is clean like new for it continuesly cleans it's mop with clean water as it's mopping , understand, not even using a manual mop can clean this good, unless you manual clean it ever square foot , even then it does not roll to pick up dirt like this robot., Most of all you need to do is push buttons on the eufy app and it can spend as much time as needed, hours if need be cleaning the foor, this is a life changer. I have been somewhat please with this eufy mop vac. Kind of a love hate. Love it works so good at mopping , dislike it's programs to be so gentle, not to bump into things it tends to miss corners, why why why , if it took longer to mop spending time to clean the corners , it would be near perfect
I perchased last year and ran it every night, with only issue 2 times the self empty dust bins tunnel clogged from a rigid peace of plastic, not complaining, so do my sinks clog sometimes , I used the same thing that unclogged the sinks , took about 10 seconds to dislodge the plastic with a cheep dollar store sink unclogger, just a thin flexible peace of plastic with like plastic hooks on it to catch the glog , realy this robot spends hours cleaning and am not concerned about spending a few minutes minutes hear and there to take care of it until---
Untill now - there was a firmware update that is was hopping would fix the skipping corner issues , wow was i wrong , after the update the first room was the kitchen, I woke up to i was hopping a clean floor as usual, when I walk in I was shocked , thought for a second there's something wrong, piles of dirt in corners like never before and near anything stainless steel , like stove and the fridge was a row of dirty dusty cat balls , I was shocked and thought maybe something wrong with the unit , so I checked it and cleaned all it's filters and sensors, then ran it again this time watching it clean the floor, it's did same thingg , it didn't even get close to the stainless steel stove and fridge inches away , corners wow not even close , then i remembered there are setting and checked then , all settings where the same , I tried other setting everything, no difference, in fact it would get worse on some safe mode setting , in fact for some reason it pushes dust or what ever under things and into corners now
Wow very disappointed, now on the other hand nothing perfect they say and like iphone I have had from there first model, apple too has had terrible updates to the piont phone was unusable, that was many decades ago and they rolled out fast new updates sometimes took a few to fix the issues , what we have hear is new technology, but what do I do in the mean time , what if it never gets fixed ? I going to take my older $158 robot vacs, does not self empty, but it does a fantastic job at vacuuming everywhere, though that one too needed 10 firmware updates just to work correct, yet they was updating weekly , the eufy has had 1 firmware update in the last year , allmost like they don't care or think anythings wrong
So now I going to have to use the old robot that probably has another 20 updates since it's been in closet and i been using the eufy eufy to vacuum the floor
Also the cost of upkeep on the eufy, run it nightly and hundreds of dollars in replacing filters rollers and so on, I never would have rote this review if this firmware wasn't so bad , please fix
Update ; it's was contacted by eufy eufy customer support, was offered a full refund, i accepted .
Then i was contacted some more with different different stories , now there offering 50% if i keep it . The issue is i need this floor cleaned daily and it's not doing this anymore . So keeping it in hopes someday they will fix it doesn't work for me , well see I am still in talks with support
There are a few flaws, though. The biggest one for me is the accumulation of slime/biofilm in the robot's dirty water reservoir (not the one on the base station, but the one on the robot itself). Emptying the tank on the base station is quick and easy, but the robot's dirty reservoir is designed to be cleaned less frequently, and it gets pretty gross. It's also a very elaborate device full of nooks and crannies and tubing, so it's impossible to really clean it. I'm trying to keep the issue under control by rinsing it regularly with boiling water. I'm not 100% sure this isn't going to damage it, but I figure I can buy a replacement reservoir if worse comes to worst. I feel like this problem could be solved, perhaps by having the base station rinse this reservoir thoroughly with fresh ozone water during the mop cleaning cycle. Or if the ozone water isn't strong enough, maybe have the base station dispense some strong disinfectant, like it does with the floor cleaner concentrate.
This brings me to the next issue, which is the lack of a fragrance-free option for the floor cleaner pods. My partner is very sentitive to fragrances, so I'm stuck mopping with plain water. It seems to work okay, but it's not ideal, and it might even be contributing to the slime issue in the dirty reservoir. Seriously, Eufy, if you're gonna require us to buy your proprietary cleaner pods, you really need to offer a free and clear option for people with allergies. Come on.
Finally, the app could use a bit more customizability, and some things just don't make sense. For example, setting the "do not disturb" hours completely prevents scheduled cleaning during that time. Why?? If I don't want the robot to clean during that time, I just won't schedule it... The whole point of "do not disturb" mode is so that the robot CAN clean, but without the extra noisy parts like bag emptying and voice announcements. I want to have the robot run at night while I'm asleep, but this is basically impossible with the current app behavior. I guess maybe some people want to prevent other residents from manually running the unit during certain hours, but that should be a separate option.
I would also love a cleaning mode that would have the robot do a vacuum-only pass, and then a vacuum+mop pass. I'm pretty sure this is a standard option in most other robovac apps. And please allow us to configure the height detection sensitivity on a per-room basis!
I have now Xiaomi, Narwal, Roborock and Eufy at home stationed at different floors. I have 2 short hair dogs and 6 cats, despite using these robotic vacuum/mop machines, I still need to hand vacuum the floor and the staircases everyday because none of these robotic ones did a good job vacuuming the floor, except Xiaomi. I have too many pets so vacuum function is not what I am going to judge here but mopping function is what matters.
Eufy even though don’t use too much water and it’s not like Narwal will go back to the station to wash the mop multiple times ( I think this is because of the water tank the robot itself carries so that it can always clean the mopping roller and collect the dirty water with it while performing), Eufy does mop the floor the best. My Roborock does an okay job and my Narwal leaves stripes on my floor which makes the floor looks greesy all the time ( I’m waiting for it to break soon 😅 so I can get a new one). Despite Eufy uses the least amount of water to clean the floor but my floor feels super clean and I would walk on the floor barefoot to feel the cleanliness which I haven’t got from any of my experiences from the formal robots I used. With my Narwal, I have to refill water tank and dump the dirty one every time I run it and I run the machine almost everyday if not every other day and it’s quite annoying. With Eufy, I’ve had it for almost a month and I think I only refilled the water like 3 times and the dirty water tank was dumped like 4 times ( not even 1/3 full when I cleaned it, I didn’t want the dirty water to stay in the tank too long or it smells.
The suction power is not the best which I knew before purchasing ( I did a lot of homework) but it still does a decent job. I hand vacuum the floor almost everyday so it doesn’t matter to me anyways.
Overall, I’m very satisfied with the purchase but I wish the dirt water tank can be a bit smaller so that I get a reminder to dump it sooner since it uses so little of water 😂😂 Best past, it doesn’t leave marks on my floor which I love a lot.
Factors: large dog (golden retriever), doggie door to the outside, large multi-floor home with complex layout, gigablast fios internet with mesh wifi router (fast and reliable WiFi signal throughout home).
The brand: To be fair and upfront, there was a thumb on my scale towards Eufy because we already have their security cameras, locks, and home base, but I do not need everything to be linked , so we did consider other options. I was tepid Eufys customer service after having to use it a few times. Their customer service is definitely based in India and they are absolutely looking to resolve issues instead of solve them, but I feel that way about most large companies. The smaller for me was The Eufy interfaces (app, etc). They are better than anything else I’ve used on the market.
Pros:
1. The app and general interface on this thing is amazing. So much easier to use and gives you way more control. You can see from the pictures, the iRobot mapping feature is not accurate and gives you limited control. Also, the iRobot frequently ignores its own rules like do not disturb. I had to consistently manually shut off the vacuum during my working hours. Finally we have a large house and the irobot would get lost and not be able to return home. We found it dead in the house daily. We would have to figure out where it finally died since it was different every time. The Eufy hasn’t gotten lost at all since its mapping is so much better and the order it cleans anticipates the return to its base. Can’t say enough about the mapping feature.
2. The vacuum works way better than the iRobot versions. It may seem strange but I believe a lot of it has to do with the pattern it vacuums in. The grid is way more effective and it leaves a cleaner look. The suction is really good for pet hair and dander. It is also a champ at the dirt and leaves the dog brings in through the doggie door. It does lose a point when it comes to dog food. It maybe able to handle some of the smaller stuff but I have a large dog and it just pushes around his food. This is the one area iRobot shined. It handled dog food amazingly. It was like a tank crawling over carpets with a high clearance, so maybe that is the difference. I did turn off the eufy small object setting and that helped but it still struggles. Overall the eufys cleaning pattern, ability to control the suction and times it cleans a room (at the room, zone, or schedule level) more than makes up for the dog food issue, but I did take one star away.
3. The navigation and ability of the little robot is so much better. All the iRobots would continually get stuck under kitchen cabinets, bathroom cabinets, and living room furniture. It was to the point we had to save it at least once a day. There was no set it and forget it on that thing. The Eufy doesn’t struggle nearly as much. It is still gets caught on cords and large particles but it is way more rare and is also a lot easier to fix when it does. Often with the iRobot I would have to take it back to its base and restart the entire cleaning cycle to get it to start cleaning again. Having to start the cleaning cycle over again caused all sorts of issues.
4. This is my first mopping vacuum but that’s not because I am not familiar with the market, just the opposite. This is the first time I’ve felt that the market has offered a mopping product I would like. In the past wet carpets, stinky mildewy pads, and lack of practicability prevented me from purchasing. So far, this one works really well…for what it is. To be fair, this is mopping a floor in the same way using a swiffer wet jet is. This is not a deep clean. Now, if it mops on a daily basis, it could probably prevent a lot of the need to deep clean. But this is definitely geared towards maintenance and your floors should start out clean.
Cons:
1. The subscription. It’s always the subscription. No, it’s not the typical subscription where the product won’t work unless you pay monthly, but you can only use eufy floor cleaner. Eye roll. Time will tell how much I’m willing to pay for the mopping, especially given its perceived value. I may end up just using water and deep cleaning on my own. We will see.
2. The vacuum itself is much quieter than the iRobot, however the base is much louder. That means when it goes to clean itself or empty one of the containers it’s definitely loud. It will disrupt what you’re doing. With that being said, I’ve had to send back my iRobot base three times before abandoning the product because the suction was not enough. I will take loud over non-functioning any day.
Mopping Performance:
After running just one-pass cleaning, my hardwood floor is really squeaky clean. That is in the areas it would reach. Unfortunately, sometimes the robot would avoid getting too close to the under-cabinet in the kitchen. There is a setting to set the Height Detection Sensitivity from "Safe Mode" to "Medium" or "Free Mode" which would make the robot vacuum to take some risks and get close to the tight spaces but you run the risk of it taking too much risk and getting stuck. In my case, it went under the couch and got stuck, scratching the glossy surface. Ugh.
Vacuuming Performance:
When it comes to carpet cleaning, it's not great though. Now, I understand this is a robot vacuum and it doesn't clean like a dedicated upright or even a cordless vacuum, like my Dyson V10. But it misses to pick up some of my dog's hair clumps on areas on the carpet. Sometimes, if the hair clumps are big enough it would just go around them thinking they are obstacles. You can turn off "Small Object Less Collision Mode" feature which would make allow to ignore those large clumps as obstacles, but then you risk of other things like a phone charger or smaller items to be run over and risks getting stuck in the roller.
Drop Sensor Issue:
After reading some comments on Reddit, I realized that it's a common problem with robot vacuums to not work on dark carpets or carpets with black patterns on them, which I have in one area of my living room. This is because the robot vacuum has a sensor that prevents it from falling off the stairs or drop-offs. These robots can't distinguish that from a black carpet or a real drop. The Eufy S1 is not immune to this issue. It skips certain parts of my area rug. It pauses, reverses, and goes around them. I think with all the built-in LIDAR and cameras on board, I was hoping it can be smarter than that. Now, I thought it would be safe to leave the robot to vacuum my second floor and not fall off the stairs. Boy, was I wrong! Luckily, it only fell one step off the stairs. To mitigate this, I had to set up a virtual wall before the stairs but I now had to remember to manually vacuum the remaining 6-inch gap beyond the virtual wall. Here’s the irony here. It stops on very dark carpets because of drop sensor but wasn’t effective at keeping it from falling off the stairs.
Conclusion:
Overall, I do want to keep it because it's a really good RoboVac for hard floors. I do hope most of the issues I mentioned can be fixed by firmware. The poor carpet vacuuming performance is unfortunate. I could get a second vacuum for my mostly-carpet second floor but that's like spending another $400 to $500 which I wasn't looking forward to doing. If that's the case, I'm thinking if another product would be a good hybrid mop/vacuum combo even if it's not as good as the Eufy S1 Pro.
I just ordered the Dreame X40 Ultra ($1,899) to see if it's any better. I heard good and bad things about it. I have a feeling that the mopping ability would not match the Eufy S1 Pro and I'm hoping that at least it's better in carpet vacuuming and the navigation is better especially not falling off the stairs. Let's see.
UPDATE: Well… the Dreame X40 Ultra stopped working after just 2 rooms and 3 cycles of cleaning. I’m obviously returning it. And I just reordered the Eufy S1 Pro.
