Abstract

A surface cleaning apparatus comprising a base; an upright handle assembly pivotally mounted to the base and including an upright housing at a lower portion thereof, a handle tube extending upwardly from an upper end of the upright housing and a push rod that is axially slidable within the handle tube; wherein the handle tube is mounted for telescoping movement within upright housing between an extended position and a stowed position within the upright housing; a fluid delivery system including a fluid supply tank for holding a supply of a cleaning fluid; a fluid distributor for distributing the cleaning fluid from the fluid supply tank onto the surface to be cleaned; and a fluid conduit, including a fluid flow controller, between the fluid supply tank and the fluid distributor. A locking collar on the upright housing locks the handle tube in the extended and stowed positions.

Claims

1. A surface cleaning apparatus comprising:

a base, which is adapted to move along a surface to be cleaned;

an upright handle assembly pivotally mounted to the base and including an upright housing at a lower portion thereof, a handle tube extending upwardly from an upper end of the upright housing and a push rod that is axially slidable within the handle tube;

wherein the handle tube is mounted for axial movement within upright housing between an extended position in which at least a portion of the handle tube extends outside of the upright housing and a stowed position in which the portion of the handle tube is received within the upright housing;

a fluid delivery system including;

a fluid supply tank for holding a supply of a cleaning fluid;

a fluid distributor for distributing the cleaning fluid from the fluid supply tank onto the surface to be cleaned; and

a fluid conduit, including a fluid flow controller, between the fluid supply tank and the fluid distributor.

2. The surface cleaning apparatus according to claim 1 wherein the upright handle assembly further comprises a connector that is mounted for selective movement between a connected position, in which the push rod and the fluid flow controller are connected for selective control of the fluid flow controller, and a disconnected position, in which the push rod and the fluid flow controller are disconnected.

3. The surface cleaning apparatus according to claim 2 wherein the connector is in the connected position when the handle tube is in the extended position and is in the disconnected position when the handle tube is in the stowed position.

4. The surface cleaning apparatus according to claim 2 wherein the upright handle assembly further comprises a handle grip mounted to an upper end of the handle tube and a manually actuator that is connected to the push rod for selective axial movement of the push rod when the handle tube is in the extended position for controlling the flow of fluid between the fluid supply tank and the distributor.

5. The surface cleaning apparatus according to claim 2 wherein fluid flow controller is a valve.

6. The surface cleaning apparatus according to claim 5 where the valve is a mechanically operated valve that is opened by axial movement of the push rod when the connector is in the connected position.

7. The surface cleaning apparatus according to claim 5 where the valve is an electrically operated valve that is opened by axial movement of the push rod when the connector is in the connected position.

8. The surface cleaning apparatus according to claim 2 wherein the connector comprises a lever that is pivotally mounted for movement between an aligned position in which it is in registry with the push rod and a misaligned position in which it is out of registry with the push rod.

9. The surface cleaning apparatus according to claim 8 wherein the upright housing further comprises a collar that is mounted to the upper end thereof for rotational motion and that receives the handle tube in a central opening thereof;

and a sheath rotationally mounted to the collar, at least partially surrounding the push rod, and keyed to the collar for rotation therewith, and the sheath includes a cam rib that is configured to operably contact and move the lever between the aligned position and the misaligned position.

10. The surface cleaning apparatus according to claim 9 wherein the lever it biased into the aligned position.

11. The surface cleaning apparatus according to claim 1 wherein the fluid distributor further comprises a steam generator in the fluid conduit.

12. The surface cleaning apparatus according to claim 1 and further comprises a fluid recovery system for recovering soiled cleaning fluid from the surface to be cleaned.

13. The surface cleaning apparatus according to claim 1 wherein the fluid supply tank is mounted to the upright housing.

14. The surface cleaning apparatus according to claim 1 wherein the upright housing further comprises a locking mechanism to selectively lock the handle tube in at least one of the extended and stowed positions.

15. The surface cleaning apparatus according to claim 14 wherein the locking mechanism comprises a locking collar that is rotatably mounted to the upright housing and that receives the handle tube in a central opening of the collar.
