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.

Claims

2. The hand-held portable wet/dry vacuum of claim 1 further comprising a gear train, wherein said gear train drivingly connects said turbine to said brush.

3. The hand-held portable wet/dry vacuum of claim 1 wherein a rotational axis of said brush is angled so that a portion of the brush contacts a surface to be cleaned.

4. The hand-held portable wet/dry vacuum of claim 1 further comprising at least one air inlet in a wall of said motor housing for allowing cooling air into said motor housing, said inlet is located on a plane spaced above a plane of said air passageway to prevent liquid from entering said motor assembly.

5. The hand-held portable wet/dry vacuum of claim 1 further comprising a siphon located within said cleaning fluid tank, wherein said siphon siphons cleaning fluid for distribution onto a surface to be cleaned.

6. The hand-held portable wet/dry vacuum of claim 5 further comprising a siphon actuator connected to said siphon for operating said siphon.

7. The hand-held portable wet/dry vacuum of claim 6 comprising a spray tube connected to said siphon for distributing cleaning fluid onto a surface to be cleaned.

8. The hand-held portable wet/dry vacuum of claim 1 wherein said dirty fluid tank further comprises a drain cap that covers an opening for draining said dirty fluid tank.

9. The hand held portable wet/dry vacuum of claim 1 further comprising a switch located on said motor housing, wherein said switch is operably connected to said valve to control movement of said valve.

10. The hand held portable wet/dry vacuum of claim 1 wherein said cleaning fluid tank comprises a handle portion.

11. The hand held portable wet/dry vacuum of claim 1 wherein said motor housing is positioned on a top surface of said dirty fluid tank, wherein said dirty fluid tank is wedge shaped to position said motor housing above said suction nozzle.

12. The hand held portable wet/dry vacuum of claim 1 wherein at least a portion of said suction nozzle is of one piece with said cleaning fluid tank.

13. A hand held wet/dry vacuum comprising:

a cleaning fluid tank, said cleaning fluid tank comprising a siphon located within said tank, wherein said siphon withdraws cleaning fluid from said tank for distribution onto a surface to be cleaned;

a motor housing, wherein said cleaning fluid tank is selectively mounted on one side of said motor housing;

a dirty fluid tank selectively mounted on said motor housing on an opposite side from said cleaning fluid tank;

a brush, wherein said brush is operably connected to a means for powering said brush;

wherein said motor housing houses a suction fan and motor assembly;
