ABSTRACT:
A method and apparatus configured to be driven by a source of negative pressure for cleaning the interior surface of a containment wall and the upper surface of a water pool contained therein. The apparatus includes a unitary body suited for immersion in the water pool, a negative pressure source for producing a water flow in the body; a level control subsystem carried by the body responsive to the water flow for producing a vertical force to selectively place the body either (1) in a first mode proximate to the water surface or (2) in a second mode proximate to the wall surface below the water surface; at least one pool water inlet in the body; and a propulsion control subsystem responsive to the water flow for selectively moving the body either (1) along a path adjacent to the water surface for collecting pool water therefrom through said inlet or (2) along a path adjacent to the wall surface for collecting pool water therefrom through said inlet. The cleaner body has 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).
