Claim:
An aquaculture cage screen cleaning device comprising; a brush head including a strip having a plurality of holes and a plurality of flexible hook shaped fingers formed on said strip, said brush head in operative engagement with a power output to cause said brush head and said plurality of flexible hook shaped fingers to move across an aquaculture cage screen having an inner surface and an outer surface, said flexible hook shaped fingers are made from a thermoplastic elastomer with a durometer of 40 to 90 A shore scale being sized and configured to elastically deform around individual screen strands that form said aquaculture cage screen to disengage growth therefrom, wherein the placement of said brush head on a screen surface of said aquaculture cage screen permits said flexible hook shaped fingers to clean the inner and outer surfaces of said aquaculture cage screen from the same side surface, wherein the plurality of flexible hook shaped fingers on said brush head is moved in a rotating manner, whereby the flexible hook shaped fingers along a leading edge of said brush head elastically deform around individual screen strands that form said aquaculture cage screen to disengage growth therefrom in a first direction and then in a second direction as the brush head rotates and the trailing edge of the brush head passes over the screen, said brush head has a plurality of propeller blades extending radially from a hub an inner diameter to a ring such that when said brush head is moved in a rotating manner it produces forces for advancing the motion of the brush head, said ring includes pins placed about a circumference of said ring, said pins are sized and configured to mate with complimentary holes formed on said strip.
