ABSTRACT:
An apparatus for cleaning algae and debris from a water treatment tank includes a carriage that is mounted for movement while extending over a clean water flow channel of the treatment tank. A motor drives the carriage around the tank while a guide maintains the carriage in the proper position for cleaning. A series of brush assemblies are connected to a frame of the carriage. The brushes of these assemblies are adapted to engage and clean the weir, baffle, spillway and clear water flow channel of the tank as the carriage moves. Additionally, a directional controller automatically controls the direction of operation of the motor and hence the direction of movement of the carriage. The directional controller also includes a sensor adapted to sense any obstructions, such as a service walkway, extending across the movement path of the carriage. Upon sensing an obstruction, the direction of movement of the carriage is reversed.
