All dirt and debris will be easily removed when you use the Kreepy Krauly Lil Shark aboveground pool cleaner. This powerful and effective suction cleaner scrubs and vacuums your pool. Suctions cleaners are attached via a 1.5 inch hose to a vacuum plate in the skimmer, or to a dedicated vac line on the side of the pool. The suction provided by the pool's pump causes the robot to move forward along the floor and walls of the pool picking up dirt and debris as it moves.
