Surface cleaning apparatus with accessory working air path

1. A surface cleaning apparatus comprising:

a housing including a base and an upright handle pivotally mounted to the base for manipulation of the base along a surface to be cleaned and for movement between an upright position and an inclined position;

a recovery tank mounted to the base;

a hose having a first end mounted to the handle and a second end adapted for connection to an accessory cleaning tool;

a first coupling on the handle in fluid communication with the first end of the hose;

a second coupling on the base in fluid communication with the recovery tank and in registry with the first coupling when the handle is in the upright position and out of registry with the first coupling when the handle is in the inclined position; and

a vacuum source fluidly coupled with the recovery tank and fluidly coupled to the hose when the handle is in the upright position with the first coupling in registry with the second coupling to draw dirt through the hose into the recovery tank.

2. The surface cleaning apparatus of claim 1 and further comprising a suction nozzle associated with the base and a diverter valve selectively fluidly coupling the recovery tank with one of the suction nozzle for a floor cleaning operation mode and the second coupling for an accessory cleaning operation mode.

3. The surface cleaning apparatus of claim 2 and further comprising a working air conduit that is in fluid communication with the suction nozzle, the second coupling, and the recovery tank, wherein the diverter valve is rotatably mounted in the working air conduit and has an external knob for movement of the diverter valve between a floor cleaning position for the floor cleaning operation mode and an accessory cleaning position for the accessory cleaning operation mode.

4. The surface cleaning apparatus of claim 3 , wherein the diverter valve has a top wall, a side wall, and an open bottom in communication with the recovery tank, and the side wall has an opening that alternatively fluidly couples the suction nozzle or the second coupling with the open bottom.

5. The surface cleaning apparatus of claim 1 , wherein the first end of the hose is mounted to a lower portion of the handle.

6. The surface cleaning apparatus of claim 1 , wherein the handle forms an interior cavity, and the surface cleaning apparatus further comprises a conduit located in the cavity and coupling the hose to the first coupling.

7. The surface cleaning apparatus of claim 6 and further comprising a third coupling connecting the conduit to the hose.

8. The surface cleaning apparatus of claim 1 , wherein the handle comprises a pair of legs pivotally mounted to the base, and the first coupling is located between the legs.

9. The surface cleaning apparatus of claim 8 , wherein the handle forms an interior cavity, and the surface cleaning apparatus further comprises a conduit located in the cavity and coupling the hose to the first coupling.

10. The surface cleaning apparatus of claim 1 , wherein the hose is removably mounted to the handle.

11. A surface cleaning apparatus comprising:

a housing including a base and an upright handle pivotally mounted to the base for manipulation of the base along a surface to be cleaned and for movement between an upright position and an inclined position;

a suction nozzle associated with the base;

a hose having a first end mounted to the handle and a second end adapted for connection to an accessory cleaning tool;

a recovery tank mounted to the base;

a suction nozzle working air path formed between the suction nozzle and the recovery tank;

an accessory working air path formed between the hose and the recovery tank when the handle is in the upright position and separated when the handle is tilted from the upright position;

a vacuum source in fluid communication with the recovery tank to draw a vacuum on the recovery tank; and

a diverter valve selectively fluidly communicating the recovery tank with one of the suction nozzle working air path and the accessory working air path to draw dirt through one of the suction nozzle and the hose into the recovery tank.

12. The surface cleaning apparatus of claim 11 , wherein the accessory working air path is formed partially in the base and partially in the handle.

13. The surface cleaning apparatus of claim 12 and further comprising a coupling that joins the portion of the working air path formed in the base and the portion of the working air path formed in the handle when the handle is in the upright position.

14. The surface cleaning apparatus of claim 13 , wherein the handle forms an interior cavity, and the portion of the working air path formed in the handle is formed by a conduit located in the interior cavity.

15. The surface cleaning apparatus of claim 14 and further comprising a hose coupling that couples the conduit with the first end of the hose.

16. The surface cleaning apparatus of claim 13 , wherein the handle comprises a pair of legs pivotally mounted to the base, and the coupling is located between the legs.

17. The surface cleaning apparatus of claim 11 , wherein the diverter valve is mounted on the base for rotational movement between a floor cleaning position where the diverter valve fluidly communicates the suction nozzle working air path with the recovery tank and an accessory cleaning position where the diverter valve fluidly communicates the accessory working air path with the recovery tank.

18. The surface cleaning apparatus of claim 17 , wherein the diverter valve has a top wall, a side wall, and an open bottom in communication with the recovery tank, and the side wall has an opening that alternatively fluidly couples the suction nozzle working air path or the accessory working air path with the open bottom and thereby the recovery tank.

19. The surface cleaning apparatus of claim 11 , wherein the hose is mounted to a lower portion of the handle.

20. The surface cleaning apparatus of claim 11 , wherein the hose is removably mounted to the handle.
