ABSTRACT:
The apparatus includes a support mechanism for supporting the cleaning apparatus in the body of water, a hull cleaning assembly including a plurality of brush assemblies, and a mechanism for moving the brush assemblies between hull cleaning positions and hull clearing positions. The brush assemblies each have a buoyancy element, a motor supported by the buoyancy element, and a cleaning brush coupled to a drive shaft of the motor. The buoyancy elements of the brush assemblies are hinged together to constitute a unified hull cleaning assembly. The moving mechanism includes a control device for controlling the movement of the brush assemblies. In addition, the moving mechanism includes a plurality of control lines movably engaging the support mechanism. The control lines are connected to the brush assemblies respectively at one end and to the control device at the other end. The support mechanism includes a pulley arrangement rotatably secured therein. The control lines movably engage the support mechanism through the pulley arrangement. Methods are also contemplated by the present invention. These methods comprise the steps of (1) supporting the cleaning apparatus in the body of water; (2) maneuvering the boat hull over the brush assemblies; (3) floating the brush assemblies to a cleaning position around a bottom portion of the boat hull by employing the buoyancy elements of the brush assemblies; and (4) actuating the cleaning brushes of the brush assemblies into a cleaning action by driving the motors of the brush assemblies.
