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.
Claims17
A wet/dry bare floor cleaner comprising:
- a base;
- a handle pivotally connected to the base for movement between a first position forward of a vertical position and a second position rearward of the vertical position;
- a recovery system comprising:
- a wet suction nozzle;
- a dry suction nozzle;
- a recovery tank for receiving wet and dry debris;
- a working air conduit extending from each of the dry suction nozzle and the wet suction nozzle to the recovery tank;
- a diverter mounted in the working air conduit and movable 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;
- and
- a motor/fan assembly mounted to one of the handle and the base and adapted to create a working air flow in the working air conduit from at least one of the dry suction nozzle and the wet nozzle and to the recovery tank;
- and
- a shut-off valve mounted in the recovery tank and adapted to prevent fluid communication between the motor/fan assembly and the recovery tank when the amount of liquid in the recovery tank reaches a first predetermined amount when the handle is in the first position and a second predetermined amount different than the first predetermined amount when the handle is in the second position.
