I have mixed feelings about this robot! Its easy to get it going! Suction is amazing, cleans my small house in about 40 minutes. It misses obvious mess on the floor, its hard to get it to do its spot cleaning, i feel like it gets confused and then just stops. I had to delete it from app and re add it. App is ok, but it doesnt have much of anything. Its pain in to add rooms. You have to re explore everything. If you are techy as myself, its annoyance. But do i love andy mcclean? Absolutely! I turn it on when i leave house and by the time i come back it did the hard work! Just make sure you remove all ALL obstacles!
