This newly designed above ground RoboKleen has a longer cord to clean larger pools and extra traction – even cleans above ground pools with hoppers. This fully automatic cleaner has a self-contained filtration system so it will not clog up your pump and filter. Since it filters the water as well as cleans your pool, it can also cut chemical costs and electricity expense. Just drop this robotic dynamo into your pool, plug it in and away it goes – cleaning the pool floor without hoses to connect or wrestle with! Robo-Kleen utilizes its own internal computer to clean your above-ground pool, and then shuts itself off when the job is done
