We've only had it for a few days, but I've run it a lot already to test it and honestly, play around as well. This is by far a lifesaver, and I can truthfully say that our floors have never been cleaner with such low maintenance.
*** Pros ***
1. You can run this thing whenever (even when you're not home), in any place, room, zone, etc. - you don't have to do an entire floor when you just want one room or spot.
2. My floors have never been cleaner. Simple as that - the suction on this thing is incredible. And it's not very loud at all, especially on "balanced" mode.
3. The Roborock app is extremely intuitive and feature-filled. Lots of different options and controls. Takes some getting used to at first, but its great.
4. It goes under my bed, nightstands, and dresser - which are places that are a nightmare to vacuum regularly. I didn't even think it would when I first bought it (kind of an afterthought), but I saw it do with my own eyes and that earned a star or two itself. AND it went under my dining tables, in between chairs, to get every spot. As long as the space is wide enough for the robot to get through, it'll clean it. Again - wasn't imaging that it would do that!
5. They update the firmware, so you know they are supporting and improving their products. Spending this much from a brand that isn't as well known is a risk, but that part at least made me more comfortable. Also, there is a subreddit for Roborock, where you can get some support and learn more.
6. I have a roughly 3/4-inch room transition between my mud room and kitchen...and I was worried the robot wouldn't climb it. Silly me, this thing goes right over it! Doesn't mean it will do it with any transition, maybe it's the shape of mine...no idea, but it does it with ease!
*** Cons *** (Mind you I still gave a 5-star rating, so these aren't deal breakers by any means, more of an FYI)
1. I can echo what some of the reviewers said about how this isn't truly "mopping". You cannot use any cleaner, polish, or disinfectant with it (good idea for the future for them though, along with an additional revenue stream) - it's just running a damp cloth over the floor. So you will still have to do old fashioned mopping, or Swiffering, or something once in a while to really clean the floors. But it's fine for maintenance. AND I knew that before I bought it - know one should buy this thinking that it's going to truly mop
