초록 ▼

A combination pool sweeper and vacuum cleaner is provided with a plurality of ride wheels and a pair of endless rubber tracks for movably supporting a suction chamber defining housing adjacent the pool surface to be cleaned. The suction chamber housing is provided with a bail for the attachment of a control handle for guiding the tool over the surface to be cleaned. A pair of counter-rotating brushes are driven from one of the endless rubber tracks through a gear train. A portion of this gear train, along with the suspension bearings of the rubber track, is mounted in a reciprocable bracket and includes a pair of pinions which alternately, depending on the direction of motion of the tool, engage drive gears attached to the shafts of the rotary brushes, ensuring that rotation of both brushes is always in the direction of the suction chamber of the combination tool irrespective of the direction in which the tool moves.
