Abstract

A method of cleaning a surface is provided. The method includes providing a cleaning head, a housing, a pump, the pump having a port, the cleaning head having a nozzle, the cleaning head and housing being connected to one another. A cleaning element is attached with a first opening to the cleaning head so that the nozzle and the first opening are aligned. A refillable rigid container is provided having a cleaning fluid in the refillable rigid container. The port and the refillable rigid container are connected to form an air and fluid tight connection between the port and the container. The cleaning element is placed on a surface to be cleaned. The cleaning fluid is pumped from the refillable rigid container through the nozzle and the first opening onto the surface to be cleaned.

Claims (29)

1. A method of cleaning a surface, comprising:

providing a cleaning head, a housing, a pump, the pump having a port, the cleaning head having a nozzle, 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 aligned;

providing a refillable rigid container having a cleaning fluid in the refillable rigid container, the refillable rigid container having a vent that defines a valve, the vent being disposed between the cleaning fluid and an atmosphere and configured to flow gas to between the atmosphere and the rigid container in response to a negative or positive pressure within the rigid container being above a predetermined level;

connecting the port and the refillable rigid container to form an air and fluid tight connection between the port and the container;

placing the cleaning element on a surface to be cleaned; and

pumping, via the pump and an opening of the vent, the cleaning fluid from the refillable rigid container through the nozzle and the first opening onto the surface to be cleaned.

2. The method of claim 1 , wherein the vent is normally closed and is opened by negative pressure applied on the refillable rigid container by the pump.

3. A method of cleaning a surface, comprising:

providing a cleaning head, a housing, a pump, the pump having a port, the cleaning head having a nozzle, 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 aligned;

providing a refillable rigid container having a cleaning fluid in the refillable rigid container;

connecting the port and the refillable rigid container to form an air and fluid tight connection between the port and the container;

placing the cleaning element on a surface to be cleaned;

pumping, via the pump, the cleaning fluid from the refillable rigid container through the nozzle and the first opening onto the surface to be cleaned,

wherein the pumping step further comprises opening a vent on the refillable rigid container, wherein the vent is normally closed and is opened by negative pressure applied on the refillable rigid container by the pump, and

wherein the vent is the only valve in a fluid path from the refillable rigid container through the spray nozzle.

4. The method of claim 1 , wherein the cleaning head includes at least one cover member, and the method further comprises trapping any cleaning fluid from the nozzle between the at least one cover member, the nozzle, the cleaning element, and the surface to be cleaned.

5. 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.

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 refillable rigid container 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 step of connecting the port and the refillable rigid container comprises forming a removable fluid and air tight connection with an inlet of the pump.

10. The method of claim 1 , wherein the step of providing the refillable rigid container with the cleaning fluid comprises:

removing a removable cap from the refillable rigid container;

filling the refillable rigid container with the cleaning fluid; and

replacing the removable cap on the refillable rigid container.

11. The method of claim 10 , wherein the step of providing the refillable rigid container with the cleaning fluid further comprises moving a hinged cover of the housing to uncover the removable cap before removing the removable cap.
