Best Purchase for my room
Color: White
I was skeptical at first but I’ve been using it for about 2-3 months, and it runs every day at 6am and it has never failed me. It always has a full filter at the end for the week, and the app is very good. When it would get stuck in places, it would always find a way out and I’ve never had to manually fix it. What’s even better is that there are 100-300 dollar roombas out there and yet this one has outperformed the expensive ones. They even are going to send me 4 free filters and 4 free brushes just for using it daily.

Doesn't last
Color: White
This product was working well. I used it daily but all of a sudden after 8 months it just stopped charging. I wish it actually lasted because it was a great product. But since it now no longer charges its of no use and a waste of money smh

Amazing little robot with roller mops - Eufy has come a long way
Upgraded from an old Eufy unit that would bounce around all the objects in my house at random and did a mediocre job, and needed to be emptied daily due to the amount of dog hair, not to mention detangling the thing daily as well. But worked ok while we had it. This unit has been an enormous upgrade, not only does it not get stuck on every sock in my house, but it actually mops my floors! My wife didn't think it would make that big of a difference but it's been a huge lifesaver and quality of lifesaver especially. Even with all the dog hair the unit anti-tangle brush does an excellent job with maintenance one to two weeks to perform some basic detangling which is much easier to do now as well given the parts and how they come apart. Personally I like the proprietary detergent, it seems to be going a long way, and I know it's the perfect amount for what the unit needs which means less work for me when I need to refill the water tanks. Also the scheduling features are nice in that it can vacuum daily and mop every few days since I don't need that done daily.
My only feedback so far that would be negative at all are
1) there is one particular spot in our house at my standing desk where the robot gets stuck on occasion. It seems like it could be fixed easily with a software update to avoid climbing over something that it can't get down from.
2) The water tanks are not sealed at the top so you can't set them down once you fill them or else you'll spill water everywhere. Makes it kind of inconvenient to work with, but knowing that makes it easy to avoid.
3) the find my robot button is hidden deep in the app it should be one of the first things you see. When it got stuck somewhere it took me longer to find the button than it did to find the robot.

Arrived covered in water, brush errors when trying to run
Unit came completely covered in water. Minimal care taken with this "like-new" unit, had been leaking water into the plastic bag. Even with that, I gave it the benefit of the doubt and still finished setting it up. Within the first 30 seconds it was already reporting an error with one of the brushes. They would barely spin, stop, and fail. Even after thorough cleaning, the error persisted. The unit also struggled to find the home dock even when placed next to it, eventually erroring out as well.
Given how many issues this had within 5 minutes of opening the like-new box, I returned this for a refund.
