Abstract
A hand-held submersible power cleaner for cleaning debris from a swimming pool includes a housing having an inlet at a front end thereof which communicates with an interior cavity of the housing. An intermediate conduit having front and rear ends extends through the interior cavity. A filter is positioned between the inlet and front end of the intermediate conduit. A removable drive assembly having an impeller at a forward end and a power switch at the opposing end is removably inserted into the housing such that the impeller faces the rear end of the intermediate conduit. Dual outlet conduits communicate with the rear end of the intermediate conduit, wherein the impeller draws water and debris through the inlet, the filter occludes the debris and retains it in the cavity while the water flows through the filter assembly into the intermediate conduit, and is discharged through the dual outlet conduits at the rear of the housing.
