Abstract

A cleaning device is provided that includes a housing, a cleaning head, a flexible pouch, a cleaning element, and a spray nozzle. The housing defines an internal cavity having a power source in selective electrical communication with a pump. The flexible pouch is removably stored in the housing and includes a cleaning fluid therein. The pouch forms a fluid and air tight connection with an inlet of the pump. The cleaning element is connected to the cleaning head and has a first spray opening. The spray nozzle is in fluid communication with an outlet of the pump. The spray nozzle is positioned on the cleaning head so as to spray the cleaning fluid from the flexible pouch through the first opening onto a surface being cleaned.

First claim

What is claimed is:

1. A cleaning device comprising:
a cleaning element having a first spray opening;
a cleaning head having the cleaning element connected thereto;
a housing defining an internal cavity, the cleaning head being connected to the housing;
a pump;
a flexible pouch removably stored in the internal cavity, the flexible pouch forming a fluid and air tight connection with an inlet of the pump and having a cleaning fluid therein; and
a spray nozzle having a fluid tight and air tight connection with an outlet of the pump, the spray nozzle being positioned on the cleaning head so as to spray the cleaning fluid from the flexible pouch through the first spray opening onto a surface being cleaned.

2. The cleaning device of claim 1 , wherein the pump is an electric pump, the housing further comprising a power source in selective electrical communication with the electric pump.

3. The cleaning device of claim 1 , wherein the flexible pouch comprises a liner of a fluid container.

4. The cleaning device of claim 1 , wherein the flexible pouch collapses as the cleaning fluid is sprayed by the pump.

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

6. The cleaning device of claim 5 , wherein the cleaning head and the cleaning element, when the cleaning element is in contact with the surface to be cleaned, trap any spray from the spray nozzle between the cleaning device and the surface to be cleaned.

7. The cleaning device of claim 5 , wherein the spray 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 cleaning device of claim 1 , wherein the cleaning element is removably connected to the cleaning head.

9. The cleaning device of claim 8 , wherein the cleaning element is a microfiber cleaning cloth.

10. The cleaning device of claim 1 , wherein the flexible pouch comprises an internal valve that forms a selective fluid and air tight connection with the inlet of 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.

11. The cleaning device of claim 10 , wherein the internal valve is the only valve in a fluid path from the flexible pouch through the spray nozzle.

12. The cleaning device of claim 1 , further comprising a pouch inlet pivotally secured in the internal cavity, the pouch inlet being removably received in the flexible pouch to form the fluid and air tight connection with the inlet of the pump.

13. The cleaning device of claim 12 , wherein the pouch inlet is configured to pivot between a first position and a second position, the first position being sufficient so that the pouch inlet faces out of the internal cavity for connection and removal of the flexible pouch to and from the pouch inlet, the second position being sufficient so that the pouch inlet faces into the internal cavity for storage of the flexible pouch in the internal cavity.

14. The cleaning device of claim 1 , wherein the cleaning head and the cleaning element are triangular.

15. The cleaning device of claim 1 , wherein the cleaning head is removably and pivotally connected to the housing.

16. The cleaning device of claim 15 , further comprising a pivot member connected to a pair of supports for movement about a first axis and connected by a connector to a pair of arms for movement about a second axis, wherein the connector is removable to allow the cleaning head and pivot member to be removed from the housing.

17. The cleaning device of claim 16 , wherein the connector comprises a shoulder bolt extending through and structurally supporting the pivot member.

18. The cleaning device of claim 1 , wherein the housing further comprises an activation button for pumping fluid from the flexible pouch.

19. The cleaning device of claim 2 , wherein the housing further comprises an activation button for selectively placing the pump and the power source in electrical communication.

20. The cleaning device of claim 19 , wherein the housing further comprises a handle configured to receive an extension pole, the extension pole including a first end connectable to the handle and a second end, the second end having an supplement activation button that, when the extension pole is connected to the handle, can selectively place the pump and the power source in electrical communication.

21. The cleaning device of claim 2 , wherein the housing further comprises a handle configured to receive an extension pole, the extension pole including a first end connectable to the handle and a second end, the second end having an activation button that, when the extension pole is connected to the handle, can selectively place the pump and the power source in electrical communication.

22. A cleaning device comprising:
a cleaning element;
a cleaning head having the cleaning element connected thereto;
a housing connected to the cleaning head, the housing defining an internal cavity;
a pump in fluid communication with a pouch port;
a flexible pouch removably stored in the internal cavity, the flexible pouch removably receiving the pouch port to form a removable fluid and air tight connection, the flexible pouch comprising an internal valve that forms a selective fluid and air tight connection with an inlet of the pump; and
a spray nozzle having a fluid tight and air tight connection with an outlet of the pump, the spray nozzle being positioned on the cleaning head so as to spray a cleaning fluid from the flexible pouch onto a surface being cleaned.

23. The cleaning device of claim 22 , wherein the pump is an electric pump, the housing further comprising a power source in selective electrical communication with the electric pump.

24. The cleaning device of claim 22 , wherein the flexible pouch comprises a liner of a fluid container.

25. The cleaning device of claim 22 , wherein the flexible pouch collapses as the cleaning fluid is sprayed by the pump.

26. The cleaning device of claim 23 , wherein the internal valve is normally closed when the pump and the power source are not in electrical communication and is opened by a negative pressure applied on the flexible pouch when the pump and the power source are in electrical communication.

27. The cleaning device of claim 22 , wherein the internal valve is the only valve in a fluid path from the flexible pouch through the spray nozzle.

28. The cleaning device of claim 22 , wherein the cleaning element comprises a first spray opening and the cleaning head comprises a second spray opening, the cleaning element being removably connected to the cleaning head, the spray nozzle being positioned on the cleaning head so as to spray the cleaning fluid from the flexible pouch onto the surface being cleaned through the first and second spray openings.

29. The cleaning device of claim 2
