Dirt Devil Rampage Robotic pool cleaner. Just plug it in, push a button and drop the Rampage to the bottom of the pool. The Rampage with its powerful built in pump and filter will roam the pool scrubbing the bottom, sides, and even stairs and inclines, while you are free to do other things. Can fully clean up to a 20’x40’ pool in three hours or, if you select the quick clean cycle will clean the pool bottom in an hour. Has a 55' cord and weighs only 21.5 lbs. Works great. We are selling only because we no longer have a pool. Two new replacement filters included ($110 value).
