Electric powered automatic swimming pool cleaning system
First Claim
1. Apparatus for use with a containment wall having bottom and side portions containing a pool of water having a water pool surface, for cleaning the surface of said wall, said apparatus comprising:
- a unitary body capable of floating at the surface of said water pool;
a rechargeable electric power source carried by said body;
a level control subsystem responsive to said power source for producing a vertical force to selectively place said body proximate to said wall surface below said water surface;
at least one pool water inlet in said body; and
a propulsion subsystem carried by said body and powered by said power source for selectively moving said body along a path adjacent to said wall surface for collecting pool water through said inlet from adjacent to said wall surface.

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. The batteries can be charged from solar cells carried by the unitary body or via electric terminals in an appropriately configured docking station.
