Abstract

The present disclosure provides a surface cleaning apparatus that includes a fluid delivery system for mopping a floor surface after sweeping debris from the floor surface. The surface cleaning apparatus can have a brushroll, a collection bin that receives dirt and liquid swept by the brushroll, and a cleanout member configured to empty the collection bin and mechanically remove dirt and liquid accumulated on one or more internal surfaces of the base.

First claim

The invention claimed is:

1. A surface cleaning apparatus for cleaning a floor surface, comprising:
a supply tank;
a cleaning fluid distributor in fluid communication with the supply tank and configured to dispense cleaning fluid;
a base adapted to move over a surface to be cleaned, the base comprising:
a base housing comprising a brush chamber;
a brushroll mounted on the base housing in the brush chamber and adapted to contact the surface to be cleaned to sweep dirt and liquid;
a collection bin configured to receive dirt and liquid swept by the brushroll;
a debris outlet in at least one of the base housing and collection bin; and
a cleanout member configured to force dirt and liquid through the debris outlet, the cleanout member comprising a wiper configured to wipe an internal surface of the base, whereby movement of the cleanout member drives the wiper to mechanically remove dirt and liquid accumulated on the internal surface of the base that may otherwise be trapped within the base.

2. The surface cleaning apparatus of claim 1 , wherein the cleanout member is manually moveable by a user to force dirt and liquid through the debris outlet and comprises a handle accessible from an exterior of the base.

3. The surface cleaning apparatus of claim 1 , wherein the cleanout member is moveable along a first axis to force dirt and liquid through the debris outlet, the brushroll is rotatable about a second axis, and the first axis is parallel to the second axis.

4. The surface cleaning apparatus of claim 1 , wherein the cleanout member is configured to pulled out from the base to mechanically wipe dirt and liquid off the internal surface of the base, and eject dirt and liquid from the base through the debris outlet, whereby the collection bin is emptiable without being removed from the base housing.

5. The surface cleaning apparatus of claim 4 , wherein the collection bin is removable from the base housing.

6. The surface cleaning apparatus of claim 1 , wherein the cleanout member comprises:
a handle accessible from an exterior of the base; and
a link coupling the handle to the wiper to transmit a force on the handle to the wiper.

7. The surface cleaning apparatus of claim 1 , wherein the wiper comprises at least one of:
a brush comprising a plurality of bristles that interface with the internal surface of the base; and
an edge that interfaces with the internal surface of the base.

8. The surface cleaning apparatus of claim 1 , wherein the internal surface of the base comprises at least one of:
a surface of the collection bin;
a surface of a ramp at a rear portion of the brush chamber and extending upwardly to the collection bin, the ramp configured to guide dirt and liquid into the collection bin; and
a surface of a cover forming a portion of the base housing, the cover defining at least a portion the brush chamber.

9. The surface cleaning apparatus of claim 1 , wherein the cleanout member comprises a plurality of wipers configured to wipe a plurality of internal surfaces of the base.

10. The surface cleaning apparatus of claim 1 , wherein the base comprises a front side and at a lateral side, and the cleanout member is slidable through the lateral side of the base.

11. The surface cleaning apparatus of claim 1 , wherein the debris outlet is provided in the collection bin, and the cleanout member comprises a cover configured to close the debris outlet, and wherein movement of the cleanout member to force dirt and liquid through the debris outlet opens the debris outlet.

12. The surface cleaning apparatus of claim 1 , wherein the base comprises a door configured to close the debris outlet, and wherein movement of the cleanout member to force dirt and liquid through the debris outlet pushes the door open.

13. The surface cleaning apparatus of claim 1 , wherein the collection bin is removable from the base housing.

14. The surface cleaning apparatus of claim 13 , wherein the base comprises a pocket receiving the collection bin, the pocket having an open end at a lateral side of the base housing, wherein the collection bin is slidable out of the pocket through the lateral side of the base housing to remove the collection bin from the base housing.

15. The surface cleaning apparatus of claim 1 comprising an integrated bin/brushroll module including the brushroll and the collection bin, wherein the brushroll and the collection bin are removable from the base housing together in one action via removal of the integrated bin/brushroll module from the base housing.

16. The surface cleaning apparatus of claim 1 comprising a steam generator, wherein the cleaning fluid distributor comprises a steam distributor in fluid communication with the steam generator and configured to dispense steam.

17. The surface cleaning apparatus of claim 16 comprising:
a handheld steam unit comprising the steam generator and the supply tank; and
an elongated wand coupled with an outlet of the steam unit;
wherein the base is coupled with the wand and comprises the steam distributor.

18. A surface cleaning apparatus for cleaning a floor surface, comprising:
a steam generator;
a supply tank in fluid communication with the steam generator;
a steam distributor in fluid communication with the steam generator and configured to dispense steam;
a base adapted to move over a surface to be cleaned, the base comprising:
a base housing comprising a brush chamber;
a brushroll mounted on the base housing in the brush chamber and adapted to contact the surface to be cleaned to sweep dirt and liquid;
a collection bin configured to close receive dirt and liquid swept by the brushroll; and
a mechanical cleanout mechanism configured to force debris and liquid out of the collection bin and wipe off an internal surface of the base.

19. The surface cleaning apparatus of claim 18 wherein:
the base comprises a debris outlet; and
the mechanical cleanout mechanism comprises a cleanout member comprising a wiper configured to wipe the internal surface of the base, whereby movement of the cleanout member drives the wiper to mechanically remove dirt and liquid accumulated on the internal surface of the base that may otherwise be trapped within the base.

20. The surface cleaning apparatus of claim 19 , wherein:
the cleanout member is manually moveable by a user to force dirt and liquid through the debris outlet and comprises a handle accessible from an exterior of the base and a link coupling the handle to the wiper to transmit a force on the handle to the wiper; and
the internal surface of the base comprises at least one of:
a surface of the collection bin;
a surface of a ramp at a rear portion of the brush chamber and extending upwardly to the collection bin, the ramp configured to guide dirt and liquid into the collection bin; and
a surface of a cover forming a portion of the base housing, the cover defining at least a portion the brush chamber.
