Bests & Worsts Reviews from Amazon

Works pretty well but that thing is as dumb as a box of rocks. Update (5/17/17): I'm changing my rating from four stars to one. As of today I am no longer able to use the app for this vacuum cleaner without creating an account on iRobot's website first. What worked brilliantly until yesterday doesn't anymore today and they demand personal information for me to continue using MY vacuum that I have BOUGHT! Great - another account on some manufacturer's website that doesn't know the first thing about security and will get hacked sooner or later. And they've changed the rules long after I've bought this thing. I can't return this POS anymore now but it has become completely useless to me. DON'T BUY THIS! I would give zero stars is I could.
