ROBO-KLEEN ROBOTIC ABOVE-GROUND POOL CLEANER 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 with no hoses to connect or wrestle with! Robo-Kleen utilizes its own internal computer to clean any above-ground pool, and then shuts itself off when the job is done. The unit is entirely safe as it uses a 24 volt motor and is UL-listed. Its fine mesh filter bag can capture the tiniest particles, even algae and bacteria. Robo-Kleen's soft wheels provide traction on any vinyl liner - flat, dished, or foot-printed. The unit comes complete with a 40-foot cord and a 1-Year Warranty.
