i have had a couple robot vacuums before and they would only last maybe a month or two before I gave up on them. They would either get stuck behind a door, under a bed or just wouldn't pick anything up. I thought I had given up on them until I got this one. It is really like there is someone going around my house vacuuming. This thing is so smart it is actually pretty amazing. First, it is very easy to set up. Even someone that is not experienced in technology could do it. Love that I was able to set a schedule for vacuuming and mopping. I have 3 huskies so needless to say it is scheduled daily while I am at work. When I come home my floors are spotless. I absolutely love that when it is finished it goes back and home and empties itself. It truly gives me more time for other chores. Definitely recommend this item. So smart and SO needed for any household!
