Abstract

A method of cleaning a surface, comprising: providing a cleaning head, a housing, and a pump, the pump having a port, the cleaning head having a nozzle, and the cleaning head and housing being connected to one another; attaching a cleaning element with a first opening to the cleaning head so that the nozzle and the first opening are in registration; providing a flexible pouch having a cleaning fluid therein; connecting the port and the flexible pouch to form an air and fluid tight connection between the port and the flexible pouch; placing the cleaning element on a surface to be cleaned; and pumping, via the pump, the cleaning fluid from the flexible pouch through the nozzle and the first opening onto the surface to be cleaned.

First claim

What is claimed is:

1. A method of cleaning a surface, comprising:
providing a cleaning head, a housing, and a pump, the pump having a port, the cleaning head having a nozzle, and the cleaning head and housing being connected to one another;
attaching a cleaning element with a first opening to the cleaning head so that the nozzle and the first opening are in registration;
providing a flexible pouch having a cleaning fluid therein;
connecting the port and the flexible pouch to form an air and fluid tight connection between the port and the flexible pouch;
placing the cleaning element on a surface to be cleaned; and
pumping, via the pump, the cleaning fluid from the flexible pouch through the nozzle and the first opening onto the surface to be cleaned.

2. The method of claim 1 , further comprising trapping any cleaning fluid from the nozzle between the cleaning head, the nozzle, the cleaning element, and the surface to be cleaned.

3. The method of claim 1 , wherein the step of pumping further comprises causing the flexible pouch to collapse as the cleaning fluid is pumped by the pump.

4. The method of claim 1 , wherein the pump is an electric pump and wherein the step of pumping comprises placing the electric pump in electrical communication with a power source.

5. The method of claim 1 , wherein the flexible pouch comprises a liner of a fluid container.

6. The method of claim 1 , wherein the cleaning head further comprises a second opening, the nozzle being positioned on the cleaning head so as to pump the cleaning fluid from the flexible pouch onto the surface being cleaned through the first and second openings.

7. The method of claim 1 , wherein the nozzle is positioned on the cleaning head in a position selected from the group consisting of: recessed with respect to a bottom of the cleaning head, flush with the bottom of the cleaning head, and extending from the bottom of the cleaning head a distance less than a thickness of the cleaning element.

8. The method of claim 1 , wherein the step of attaching the cleaning element to the cleaning head comprises removably attaching the cleaning element to the cleaning head.

9. The method of claim 1 , wherein the flexible pouch comprises an internal valve that forms a selective fluid and air tight connection with the pump, the internal valve being opened by application of a negative pressure on the flexible pouch by activation of the pump and being closed by resilience of the internal valve upon removal of the negative pressure by deactivation of the pump.

10. The method of claim 9 , wherein the internal valve is the only valve in a fluid path from the flexible pouch through the nozzle.

11. The method of claim 1 , wherein the step of connecting the port and the flexible pouch comprises forming a removable fluid and air tight connection with an inlet of the pump.

12. The method of claim 1 , wherein the port is pivotally secured in the housing for movement between a first position and a second position.

13. The method of claim 12 , wherein the step of connecting the port and the flexible pouch comprises moving the port to the first position, connecting the port and the flexible pouch, and moving the port to the second position.
