A method and apparatus responsive to a positive pressure water source (10) for cleaning the interior surface of a pool containment wall (3) and the upper surface (7) of a water pool (1) contained therein. The apparatus includes an essentially unitary cleaner body (6) and a level control subsystem (124, 138) for selectively moving the body (6) to a position either proximate to the surface (7) of the water pool for water surface cleaning or proximate to the interior surface (8) 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).

[ What is claimed:] [1.] Apparatus configured to be driven by a positive pressure water source for cleaning the interior surface of a containment wall and the upper surface of a water pool contained therein, said apparatus comprising:a unitary body configured for immersion in said water pool;means for supplying a positive pressure water flow to said body from said source;a level control subsystem responsive to water flow for producing a vertical force to selectively place said body either (1) in a first mode proximate to said water surface or (2) in a second mode proximate to said wall surface below said water surface;at least one pool water inlet in said body; anda propulsion control subsystem responsive to said water flow for selectively moving said body either (1) along a path adjacent to said water surface for collecting pool water through said inlet from adjacent to said water surface or (2) along a path adjacent to said wall surface for collecting pool water through said inlet from adjacent to said wall surface.
