Patent ID: 8632677

Claim:
An aquarium bottom cleaner system for cleaning a bottom surface of an aquarium, wherein said aquarium bottom cleaner system comprises: a suction means; a powering means; a controlling means; an automatic positioning means comprising a random position effecter comprising an annular cavity, a plurality of directional intake flow apertures, a plurality of plug balls and a plurality of substantially symmetrically disposed steer apertures along an outer radial periphery of said annular cavity; and a filtering means; wherein said suction means is powered by said powering means to move untreated water to be processed by said filtering means to produce a filtered return flow, said automatic positioning means cooperates with said controlling means to move said aquarium bottom cleaner system from a current cleaning position to a new cleaning position and wherein a portion of said filtered return flow is received through said plurality of directional intake flow apertures and directed into said annular cavity to form a flow which directs each said plug ball to plug a steer aperture, leaving at least one steer aperture unplugged such that the portion of said filtered return flow can be exhausted to create a force which propels said aquarium bottom cleaner laterally from a current cleaning position to a new cleaning position.
