This robot is much quieter than a different brand I had previously.  It cleans pretty well, and it’s relatively quick.  Overall is a solid choice but I don’t love the app.  With other brands you can schedule the cleaning by room - for the Shark you can schedule by time, but it cleans the entire floor, there is no option to choose room.  So I never use the schedule clean because of this, which is a drawback.  It would be a zillion times better today it better app. Also emptying the dust bin can be messy, the way that it opens to clean it is awkward.   The addition of the mopping feature is really nice and easy to use. The technology of the robot itself is much better than other brands, but it really need an improved app.
