The Sta-Rite 'Lil Shark™ above-ground automatic cleaner scrubs and vacuums flat- or dished-bottomed pools. The patented vortex design, with only one moving part, even operates on pools with lower flow rates. Since it only has on moving part, maintenance is reduced and reliability is increased. The unit installs in minutes without special tools or fittings. Since it operates on the suction produced by your pump and filter system, it runs automatically whenever your pump is operating. 'Lil Shark™ cleans your pool, gobbling up all types of debris, but is not a wall climber. The unit comes complete with 32-feet of hose. Backed by a two-year manufacturer's warranty.
