Abstract

A hand-held portable wet/dry vacuum comprising a cleaning fluid tank, a motor housing and a dirty fluid tank. The cleaning fluid tank is selectively mounted on the motor housing. A siphon, which is controlled by an actuator, is located in the cleaning fluid tank. The dirty fluid tank is selectively mounted on the motor housing in spaced relation to the cleaning fluid tank. The motor housing houses an air driven turbine and a suction fan and motor assembly. A suction nozzle is located at a first end of the wet/dry vacuum. An air passageway extends from the suction nozzle to the suction fan and motor. The turbine communicates with the air passageway. The housing further comprises at least one air inlet to allow air to pass to the turbine. A brush is operably connected to the turbine via a gear train. A rotational axis of the brush is angled so that a portion of the brush contacts a surface to be cleaned. At least one air inlet is found in a wall of the motor housing for allowing cooling air into the motor housing. A valve is located in the air passageway and switches airflow between the turbine and the suction nozzle. Alternatively, an electric motor is used in lieu of the turbine to power the brush.
