Abstract

A surface cleaning head has a rotatably mounted brush, which is provided at a front end of the surface cleaning head, a cleaning solution delivery system and a removable liquid collection reservoir, which is provided in the surface cleaning head rearward of the brush. The cleaning solution delivery system comprises a pump, a liquid reservoir and a fluid flow path extending from the liquid reservoir to at least one delivery nozzle, wherein the at least one delivery nozzle is provided in the surface cleaning head and is configured to deliver a liquid drawn from the liquid reservoir to a portion of the brush that is located internal of the surface cleaning head.

First claim

What is claimed is:

1. A surface cleaning apparatus comprising:
(a) a surface cleaning head having a front end and a rear end positioned rearward of the front end;
(b) a brush provided at the front end of the surface cleaning head;
(c) at least one delivery nozzle provided in the surface cleaning head that is configured to deliver a liquid to a portion of the brush that is located internal of the surface cleaning head;
(d) a liquid collection reservoir provided in the surface cleaning head rearward of the brush; and,
(e) an upright section moveably mountable to the surface cleaning head between an upright storage position and a reclined surface cleaning position, the upright section comprising a wand and a handheld surface cleaning apparatus wherein the handheld surface cleaning apparatus is removably connectable to an outlet end of the wand, wherein the handheld surface cleaning apparatus further comprises a cyclone chamber.

2. The surface cleaning apparatus of claim 1 wherein the surface cleaning head further comprises a fluid flow path extending to the at least one delivery nozzle and a pump which, in operation, moves the liquid through the fluid flow path to the at least one delivery nozzle.

3. The surface cleaning apparatus of claim 1 wherein the brush comprises microfibers.

4. The surface cleaning apparatus of claim 1 wherein the at least one delivery nozzle provided in the surface cleaning head comprises a plurality of nozzles provided in the surface cleaning head are configured to deliver the liquid to portions of the brush that are located internal of the surface cleaning head.

5. The surface cleaning apparatus of claim 1 wherein, in a first mode of operation, the wand has air flow therethrough.

6. The surface cleaning apparatus of claim 5 wherein the upright section is removable and useable in an above floor cleaning mode.

7. The surface cleaning apparatus of claim 1 wherein the handheld surface cleaning apparatus further comprises an on board power source.

8. The surface cleaning apparatus of claim 1 wherein the handheld surface cleaning apparatus further comprises a collection chamber that is external to the cyclone chamber.

9. The surface cleaning apparatus of claim 1 wherein the handheld surface cleaning apparatus has a handle that comprises a pistol grip portion.

10. The surface cleaning apparatus of claim 1 wherein, in a mode of operation, the wand has an absence of air flow therethrough.

11. The surface cleaning apparatus of claim 1 wherein the wand is removable from the surface cleaning head and useable in an above floor cleaning mode.

12. The surface cleaning apparatus of claim 1 wherein the handheld surface cleaning apparatus further comprises an on board power source.
