Happy with how it cleans . Not so happy with it getting lost and trying to find its way back to the base. May be a GPS could help it. The alerts should repeat constantly to find out what’s going on. If not put back on the base when it gets lost battery drains  and you have to wait until it recharges . I liked the scheduling . It does turn on on it’s on and cleans well. It gets full goes back empties itself and keeps working . You must make sure you pick up around cables , move chairs and give it space to work, move around . If you have a lot of clutter and furniture , it may not be for you because when it needs to get back it will struggle. If your home has plenty of open areas , mixed with carpet and floors it will do a good job.  I hope the next generation fixes these challenges
