POSITIVE PRESSURE AUTOMATIC SWIMMING POOL CLEANING SYSTEM

摘要

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).
