Electric powered automatic swimming pool cleaning system

Apparatus for cleaning the surface of a containment wall configured to contain a pool of water having a water surface, said apparatus comprising:

• a unitary body:
• a rechargeable electric power source carried by said body configured to allow recharging by a docking station;
• and
• a control system carried by said body and powered by said power source, said control system including:
• a propulsion subsystem for selectively moving said body along a path adjacent to said wall surface;
• and
• a docking station mounted proximate to said containment wall for recharging said power source.

Apparatus for use with a containment wall having bottom and side portions containing a pool of water having a water surface, for cleaning the surface of said water and the surface of said wall, said apparatus comprising:

• a first unit configured to travel proximate to said water surface;
• a second unit configured to travel proximate to said wall surface;
• a power source for supplying electric energy to at least one of said first and second units;
• a conduit physically connecting said first and second units for transferring energy therebetween;
• and
• a propulsion subsystem carried by at least one of said first and second units and responsive to electric energy supplied thereto for propelling said first unit along a travel path proximate to said water surface and/or said second unit along a travel path proximate to said wall surface.
