Abstract
A method and apparatus powered from the suction side of a pump for cleaning the interior surface of a pool containment wall and the upper surface of a water pool contained therein. The apparatus includes an essentially unitary cleaner body and a level control subsystem for selectively moving the body to a position either proximate to the surface of the water pool for water surface cleaning or proximate to the interior surface of the containment wall for wall surface cleaning. The cleaner body can have a weight/buoyancy characteristic to cause it to normally rest either (1) proximate to the pool bottom adjacent to the wall surface (i.e., heavier-than-water) or (2) proximate to the water surface (i.e.. lighter-than-water).
