I also own a Roomba 890, which I have designated to clean the downstairs. while the Roomba does a good job, the bouncing from wall to wall model of cleaning (I think of this as the infinite energy rubber ball model) is inefficient. I have placed visible things on the floor for the Roomba to pick up and it might take 2 or 3 sessions for it to get them all. The Roborock however got everything I placed the first time. The, for lack of a better word "zigzag" pattern covers the entire room, and every room in which it is allowed. It also takes less time, the same area that took the Roomba 55 minutes, takes the Roborock 42, and as I said before it does a better job.
The Roomba frequently gets stuck and asks for help, the Roborock has yet to request any kind of help, other than to empty the dustbin. The Roomba went under something and dragged it's RCON off, the small "tower" in the front of the robot that senses the charging port. I had to rebuild the casing and replace the RCON. The Roborock seems to know it's limits, what it can and can't get under.
I also had a lot of things that were dragged around the room by Roomba, especially anything with a cord. So far, I haven't had this to happen with the Roborock.
I also love the way the Roborock can increase it's suction when it gets on a rug or carpet. My rugs look very good.
