Review on 120-Minute Runtime OKP K7 Robotic Vacuum Cleaner by April Anson

We have followed directions and cleaned it as instructed after each use. We used it 2-3 times a week so it's relatively easy to use. Stops working, beeps and turns off. He says to check the roller which we do, they cleaned it (it didn't clog at all) but it won't go. It was a great little device when it worked, but costing $150 and only working for about a month sucked. I hope I can return or replace.
