Abstract
A bare floor cleaner for wet and dry bare floor surfaces comprises a base with wet and dry suction nozzles and a handle pivotally connected to the base. A diverter mounted in the working air conduit between each of the dry suction nozzle and the wet suction nozzle to a recovery tank is movable by movement of the handle between a dry suction position and a wet suction position for selectively at least partially blocking working air flow from the wet suction nozzle and the dry suction nozzle, respectively, to the recovery tank. A shut-off valve is mounted in the recovery tank to prevent fluid communication between a suction source and the recovery tank when the amount of liquid in the recovery tank reaches a first predetermined amount with the handle forward and a second predetermined amount with the handle rearward.
