Abstract: A filter holder for holding an open ended filter having an open proximal end and an open distal end in an operative position on a swimming pool cleaner having a pipe stub for receiving one open end of the filter is shown and described. The filter holder includes a cap for covering one open end of the filter, a coupler configured to cooperate with and engage the pipe stub, and a spanning connector configured to span and connect the cap and the coupler outside the pipe stub of the filter. The coupler may include L-shaped brackets. A constricting collar pins the brackets to the pipe stub. The spanning connector may include compression rods and nuts. The filter holder may include an optional adapter collar separable from the coupler, to adapt diameters of the coupler and the pipe stub. The invention may alternatively be considered to be a mobile swimming pool cleaner having a pleated medium filter rather than a flaccid bag filter.

Abstract: A mobile filter for removing solid contaminants from water such as swimming pools. The mobile filter has a handle maneuvered chassis, a powered propeller housed in a propeller housing, which propeller propels water through a removable bag mesh filter installable on the propeller housing. A submersible battery pack is slidably coupled to the handle, and is readily removable therefrom. An electrical conductor spans and connects the submersible battery pack and the submersible electric motor.
