Abstract

A surface cleaning apparatus includes a housing including an upright handle assembly and a base mounted to the upright handle assembly. The surface cleaning apparatus is further provided with a fluid delivery system comprising a fluid dispenser configured to dispense fluid and at least one fluid delivery channel forming a portion of a fluid delivery pathway. A method of removing debris and fluid from a floor surface using a surface cleaning apparatus is also provided.

First claim

What is claimed is:

1. A surface cleaning apparatus, comprising:
a housing including an upright handle assembly and a base operably coupled to the upright handle assembly, the base comprising a base housing and a brushroll cover having an underside, wherein the brushroll cover is removable from the base housing;
a brushroll provided with the base, wherein at least a portion of the underside of the brushroll cover is adjacent to the brushroll;
a suction source;
a suction inlet in the base behind the brushroll, wherein the suction inlet is in fluid communication with the suction source and is configured to simultaneously ingest liquid and debris into a recovery pathway;
a fluid delivery system comprising:
a fluid supply chamber adapted to hold a supply of liquid;
a fluid dispenser in fluid communication with the fluid supply chamber, the fluid dispenser including at least one outlet; and
at least one fluid delivery channel, the at least one fluid delivery channel forming a portion of a fluid delivery pathway between the fluid supply chamber and the fluid dispenser, wherein the at least one fluid delivery channel is removable with the brushroll cover; and
a connector inlet on a lower side of the brushroll cover and fluidly coupled to the at least one fluid delivery channel by the installation of the brushroll cover on the base housing.

2. The surface cleaning apparatus of claim 1 wherein the at least one fluid delivery channel is located within the brushroll cover.

3. The surface cleaning apparatus of claim 1 , comprising an actuator provided on the upright handle assembly, the actuator operably coupled with the fluid delivery system to deliver fluid to the fluid dispenser via the fluid delivery channel.

4. The surface cleaning apparatus of claim 1 wherein the brushroll comprises a dowel and microfiber material on the dowel.

5. The surface cleaning apparatus of claim 1 , comprising an interference wiper provided on the base and adapted to interface with a portion of the brushroll to remove excess liquid from the brushroll.

6. The surface cleaning apparatus of claim 1 wherein the fluid dispenser is provided on the underside of the brushroll cover and the at least one outlet is adapted to dispense fluid onto the brushroll.

7. The surface cleaning apparatus of claim 1 wherein the base housing comprises:
the suction inlet and
a spray connector disposed above the suction inlet and behind the brushroll,
wherein the spray connector is fluidly coupled with the connector inlet by the installation of the brushroll cover on the base housing.

8. The surface cleaning apparatus of claim 1 wherein the brushroll cover comprises a lower housing and an upper cover that mate to form the at least one fluid delivery channel therebetween.

9. A surface cleaning apparatus, comprising:
a housing including an upright handle assembly and a base operably coupled to the upright handle assembly, the base comprising a brushroll cover having an underside;
a brushroll provided with the base, wherein at least a portion of the underside of the brushroll cover is adjacent to the brushroll;
a suction source;
a suction inlet in the base behind the brushroll, wherein the suction inlet is in fluid communication with the suction source and is configured to simultaneously ingest liquid and debris into a recovery pathway;
a fluid delivery system comprising:
a fluid supply chamber adapted to hold a supply of liquid;
a fluid dispenser in fluid communication with the fluid supply chamber, the fluid dispenser including at least one outlet; and
at least one fluid delivery channel, the at least one fluid delivery channel forming a portion of a fluid delivery pathway between the fluid supply chamber and the fluid dispenser; and

an interference wiper provided on the base and adapted to interface with a portion of the brushroll to remove excess liquid from the brushroll;
wherein the fluid dispenser is disposed between the interference wiper and the suction inlet to dispense cleaning fluid onto a portion of the brushroll disposed between the interference wiper and the suction inlet.

10. The surface cleaning apparatus of claim 1 , comprising a squeegee provided on the base rearwardly of the brushroll and adapted to contact the surface to be cleaned.

11. The surface cleaning apparatus of claim 1 wherein the at least one fluid delivery channel comprises a first terminal end and a second terminal end, and the fluid dispenser is provided on the brushroll cover at the second terminal end.

12. The surface cleaning apparatus of claim 1 , comprising:
a pivotable joint coupling the upright handle assembly to the base; and
a fluid supply conduit fluidly coupling the fluid supply chamber, which is disposed on the upright handle assembly, to the at least one fluid delivery channel;
wherein at least a portion of the fluid supply conduit passes through the pivotable joint.

13. The surface cleaning apparatus of claim 9 wherein the base comprises a base housing and the brushroll cover is removable from the base housing, and wherein the at least one fluid delivery channel is removable with the brushroll cover.

14. The surface cleaning apparatus of claim 13 comprising a connector inlet on a lower side of the brushroll cover and fluidly coupled to the at least one fluid delivery channel by the installation of the brushroll cover on the base housing.

15. The surface cleaning apparatus of claim 14 wherein the at least one fluid delivery channel comprises a first terminal end and a second terminal end, the connector inlet is fluidly coupled to the first terminal end and the fluid dispenser is provided on the brushroll cover at the second terminal end.

16. A surface cleaning apparatus, comprising:
a housing including an upright handle assembly and a base operably coupled to the upright handle assembly, the base comprising a brushroll cover having an underside;
a brushroll provided with the base, wherein at least a portion of the underside is adjacent to the brushroll;
a suction source;
a suction inlet in the base behind the brushroll, wherein the suction inlet is in fluid communication with the suction source and is configured to simultaneously ingest liquid and debris into a recovery pathway;
a fluid delivery system comprising:
a fluid supply chamber adapted to hold a supply of liquid;
a fluid dispenser in fluid communication with the fluid supply chamber, the fluid dispenser including at least one outlet; and
at least one fluid delivery channel integrated within the brushroll cover, the at least one fluid delivery channel forming a portion of a fluid delivery pathway between the fluid supply chamber and the fluid dispenser; and

an interference wiper provided on the base and adapted to interface with a portion of the brushroll to remove excess liquid from the brushroll; and
wherein the fluid dispenser is disposed between the interference wiper and the suction inlet to dispense cleaning fluid onto a portion of the brushroll disposed between the interference wiper and the suction inlet.

17. The surface cleaning apparatus of claim 16 , comprising an actuator provided on the upright handle assembly, the actuator operably coupled with the fluid delivery system to deliver fluid to the fluid dispenser via the fluid delivery channel.

18. The surface cleaning apparatus of claim 16 wherein the brushroll comprises a dowel and microfiber material on the dowel.
