Abstract
The invention provides a self-contained cordless electric pool and spa vacuum cleaner which is easily maneuverable over both flat and highly contoured underwater surfaces. A pump impeller, powered by an electric motor, is used to draw water through a compact filter cartridge. The efficiency of the filter cartridge allows for the use of a small motor and small battery which, in turn, result in the small size of the vacuum cleaner. All electrical components are enclosed in a watertight chamber so as to allow the entire cleaner to be submerged under water.
