Support left me on hold for 15 minutes, then gave a survey asking how they did! App stopped allowing me to chose which rooms to vacuum. Uninstall/reinstall didn't help. Can't use whole house option because robot is overwhelmed with house size (2200 sf), & does 1 of 3 things (last 2 usually): 1. Takes 6 hrs, misses parts of rooms. 2. Takes 3 hours, forgets rooms entirely. 3. Spends half its time stuck in corners & feeling its way along walls. I have been vacuuming half at a time until now
