Abstract

A handheld extraction cleaner includes a unitary body provided with a carry handle, and further provided with a supply tank, a recovery tank, and a suction source, all of which are carried on the unitary body. The various components of the extraction cleaner can be arranged for a balanced weight in hand. The supply tank can be integrated with a fluid distributor in a removable, modular unit.

Claims

1. A handheld extraction cleaner, comprising:

a unitary body provided with a carry handle;

a working air path through the unitary body having a dirty air inlet and a clean air outlet;

a suction source in fluid communication with the dirty air inlet;

a recovery tank carried by the unitary body;

a modular fluid supply assembly comprising a supply tank and a fluid distributor integrated with the supply tank;

a flow control valve at least partially controlling a delivery of fluid to the fluid distributor and configured to open upon seating the modular fluid supply assembly on the unitary body; and

including at least one of;

a receiver provided on the unitary body which places the supply tank in fluid communication with the fluid distributor when the modular fluid supply assembly is installed on the unitary body;

a flapper valve on the recovery tank configured to be pushed open by a portion of the unitary body when the recovery tank is mounted to the unitary body and to automatically close when the recovery tank is removed from the unitary body;

a flat back end on a rearward end of the unitary body configured to support the handheld extraction cleaner in a self-standing position on a surface;

a motor housing substantially enclosing the suction source and at least one baffle integrally formed with the motor housing and configured to dampen motor noise;

or

a window cleaning attachment comprising a squeegee and a foam scrubber, wherein the window cleaning attachment is removably mounted on the unitary body with the squeegee and the foam scrubber substantially below the dirty air inlet; and

wherein the modular fluid supply assembly is removable from the unitary body as a single module, such that the fluid distributor is removed simultaneously with the supply tank.

2. The handheld extraction cleaner of claim 1 wherein the flow control valve is configured to open when seated in the receiver.

3. The handheld extraction cleaner of claim 2, further comprising a pump carried by the unitary and fluidly coupled with an outlet of the flow control valve and an actuator operably coupled with the pump, wherein the actuator is provided on the carry handle.

4. The handheld extraction cleaner of claim 3, further comprising a battery pack carried by the u body and electrically coupled with the suction source and the pump.

5. The handheld extraction cleaner of claim 1 wherein the fluid distributor comprises at least one distributor outlet positioned to deliver fluid directly to the surface to be cleaned, outwardly in front of the dirty air inlet.

6. The handheld extraction cleaner of claim 1 wherein the carry handle is separate from the modular fluid supply assembly so that the modular fluid supply assembly is removable from the unitary body without removing the carry handle.

7. The handheld extraction cleaner of claim 1, further comprising a suction nozzle provided on the unitary body and defining the dirty air inlet, wherein the modular fluid supply assembly is separate from the suction nozzle.

8. The handheld extraction cleaner of claim 1 wherein the modular fluid supply assembly further comprises a bracket coupled with the supply tank, wherein the bracket carries the fluid distributor and a connector for coupling the fluid distributor with the supply tank.

9. The handheld extraction cleaner of claim 1 wherein the modular fluid supply assembly further comprises a cover for the supply tank, wherein the cover carries a portion of a lock for securing the modular fluid supply assembly to the unitary body.

10. A handheld extraction cleaner, comprising:

a unitary body provided with a carry handle;

a working air path through the unitary body having a dirty air inlet and a clean air outlet;

a suction source in fluid communication with the dirty air inlet;

a recovery tank carried by the unitary body;

a modular fluid supply assembly comprising a supply tank and a fluid distributor integrated with the supply tank; and

a flow control valve at least partially controlling a delivery of fluid to the fluid distributor and configured to open upon seating the modular fluid supply assembly on the unitary body; and

wherein the modular fluid supply assembly is removable from the unitary body as a single module, such that the fluid distributor is removed simultaneously with the supply tank and at least one of;

the fluid distributor comprises at least one distributor outlet positioned to deliver fluid directly to a surface to be cleaned, outwardly in front of the dirty air inlet, the carry handle is separate from the modular fluid supply assembly so that the modular fluid supply assembly is removable from the unitary body without removing the carry handle, the modular fluid supply assembly further comprises a bracket coupled with the supply tank, wherein the bracket carries the fluid distributor and a connector for coupling the fluid distributor with the supply tank, or the modular fluid supply assembly further comprises a cover for the supply tank, wherein the cover carries a portion of a lock for securing the modular fluid supply assembly to the unitary body.

11. The handheld extraction cleaner of claim 10, further comprising at least one of:

a flapper valve on the recovery tank configured to be pushed open by a portion of the body when the recovery tank is mounted to the unitary body and to automatically close when the recovery tank is removed from the unitary body;

a flat back end on a rearward end of the unitary body configured to support the handheld extraction cleaner in a self-standing position on a surface;

a motor housing substantially enclosing the suction source and at least one baffle integrally formed with the motor housing and configured to dampen motor noise; and

a window cleaning attachment comprising a squeegee and a foam scrubber, wherein the window cleaning attachment is removably mounted on the unitary body with the squeegee and the foam scrubber substantially below the dirty air inlet.

12. A handheld extraction cleaner, comprising:

a unitary body provided with a carry handle and having a forward end and a rearward end;

a supply tank carried by the unitary body;

a fluid distributor fluidly coupled with the supply tank;

a suction nozzle provided at the forward end of the unitary body;

a suction motor carried by the unitary body and fluidly coupled with the suction nozzle, wherein the supply tank is provided in front of the suction motor, relative to the forward end of the unitary body;

a recovery tank carried by the unitary body, wherein the recovery tank is below the carry handle and is further provided below the supply tank and the suction motor; and

a receptacle for removably mounting the supply tank to the unitary body, wherein the receptacle is provided forwardly of the carry handle and wherein at least one of;

the receptacle comprises an opening provided forwardly of the carry handle and the supply tank is insertable through the opening or further including a tank cavity provided in the unitary body below the carry handle, wherein a portion of the supply tank is insertable through the receptacle and into the tank cavity.

13. The handheld extraction cleaner of claim 12 wherein the recovery tank is substantially laterally centered below the carry handle.

14. The handheld extraction cleaner of claim 12 wherein the opening is positioned between a forward end of the carry handle and an upper end of the suction nozzle.
