Samsung POWERbot Essential Robot Vacuum: Spend less time doing chores with a vacuum that does the work for you. You'll be able to remove dirt, dust, debris and even pet hair from carpets and hard flooring. This robot vacuum automatically determines the appropriate cleaning path using Visionary Mapping Plus system navigation and avoids obstacles using a FullView sensor.
The vacuum had good suction power and was working good as expected. But after a week the left wheel got stuck and stopped working. So I returned and got a different one. The other one had the same exact problem after 3 days. I returned it back and didn't want to get a new one. Wish they fix this problem soon
