Abstract
A system for automatically cleaning swimming pools includes a unitary body having a level control subsystem for selectively moving the body to a position either proximate to the surface of the water pool or proximate to the interior surface of the containment wall, a propulsion subsystem operable to selectively propel the body in either a forward or rearward direction, and a cleaning subsystem operable in either a water surface cleaning mode for skimming or scooping or a wall surface cleaning mode for vacuuming or sweeping. The subsystems are powered by an electric source such as solar cells and/or rechargeable batteries and/or a wire extending to the unitary body from an external power source. An alternative embodiment uses separate top and bottom units tethered together by an electric conduit.
