Mapped the house perfectly, cleans in a pattern that doesn’t miss a spot, auction is great, I don’t feel grit in my feet after it cleans. The app is great and easy, notifications when it gets stuck or picks up a sock and jams are good too. 
One problem is the transition from tile to wood floorC the bump is 1/2” quarter round. It has a hard time getting over that and gets stuck in the bathroom. Wish it could climb over that transition step up.
