Patent ID: 7118632

Claim:
A device for cleaning the bottom and sides of a swimming pool comprising: a housing with a front end, a rear end, a first side and a second side opposite the first side, wherein the first and second sides extend between the front and rear ends; a pair of motor driven cylindrical brushes rotatably secured to the front and rear ends of the housing, wherein the cylindrical brushes are positioned parallel to the front and rear ends; a suction pump disposed within the housing; and a floatation element disposed within the housing and secured to the first side of the housing above the cylindrical brushes, wherein when the suction pump is disabled, the floatation element creates a floatation differential within the device thereby causing the first side to lift from the bottom of the pool and the device to pivot with respect to the pool bottom, and wherein when the suction pump is operational, a flow of water through the device overcomes the floatation differential, thereby causing the cylindrical brushes to engage with the bottom of the pool.
