Abstract
An electric-powered submersible pool cleaner includes a base, discharge conduit, and outwardly extending flange. The base includes an inlet port, and the discharge conduit extends upwardly from the base and circumscribes the inlet port and a portion of an electric-powered impeller to direct the flow of water and debris drawn through the inlet. The outwardly extending flange extends from an upper portion of the discharge conduit and secures a filter to filter debris and pass clean water back into the pool. The impeller includes one or more blades having leading and trailing edges and is set at a height such that the leading edges of the blades are positioned to extend into the discharge conduit below a lower portion of the outwardly extending flange and the trailing edges of the blades extend above the lower portion of the outwardly extending flange. A handle provides maneuverability of the cleaner.
