Abstract

A cleaning device is removably attachable to a replacement head. The replacement head includes pad that is attached to the lower side of an attachment member and is in contact with the floor during cleaning. The cleaning device is removably attached to the attachment member of the replacement head by lowering the cleaning device body downward vertically onto the replacement head until a mechanical connection is achieved.

Claims (29)

1. A replacement head for use with a cleaning device, comprising:

a housing having a dust chamber therein, a suction inlet for allowing debris to flow therethrough into the dust chamber, a portion having an opening configured to couple to a source of suction for drawing debris into the dust chamber through the suction inlet, and at least one mating element protruding from an outermost perimeter of the housing configured to removably mate the housing to a cleaning device.

2. The replacement head of claim 1 , wherein the least one mating element extends outward from a sidewall of the dust chamber.

3. The replacement head of claim 1 , wherein the dust chamber and the least one mating element are unitary with the housing.

4. The replacement head of claim 1 , wherein the at least one mating element is configured to extend into a cavity in the cleaning device.

5. The replacement head of claim 1 , further comprising a filter extending across the portion of the housing, the filter being configured to allow a vacuum force to be applied to the dust chamber while retaining debris within the dust chamber.

6. The replacement head of claim 1 , further comprising a cleaning sheet coupled to the housing and configured to contact a surface to be cleaned.

7. The replacement head of claim 6 , wherein the cleaning sheet is directly attached to the housing.

8. The replacement head of claim 6 , wherein an opening of the suction inlet is aligned with an edge of the cleaning sheet.

9. The replacement head of claim 6 , wherein the cleaning sheet is planar.

10. The replacement head of claim 1 , further comprising a release mechanism on the housing configured to release the housing from a cleaning device.

11. A replacement head for use with a cleaning device, comprising:

a unitary housing having

a dust chamber formed therein for receiving and retaining debris,

a suction inlet for allowing debris to flow therethrough into the dust chamber,

a portion configured to couple to a source of suction, the portion defining a passageway from an interior of the dust chamber to an exterior of the dust chamber, and

at least one mating element protruding from an outermost perimeter of the housing configured to removably mate the housing to a cleaning device.

12. The replacement head of claim 11 , wherein the least one mating element extends outward from at least one sidewall of the dust chamber.

13. The replacement head of claim 11 , further comprising a filter extending across the portion of the housing, the filter being configured to allow a vacuum force to be applied to the dust chamber while retaining debris within the dust chamber.

14. The replacement head of claim 11 , further comprising a cleaning sheet coupled to the housing and configured to contact a surface to be cleaned.

15. The replacement head of claim 14 , wherein the cleaning sheet is directly attached to the housing.

16. The replacement head of claim 14 , wherein an opening of the suction inlet is aligned with an edge of the cleaning sheet.

17. The replacement head of claim 14 , wherein the cleaning sheet is planar.

18. A replacement head for use with a cleaning device, comprising:

a housing having a dust chamber therein and a suction inlet for allowing debris to flow therethrough into the dust chamber, the housing including at least one projection extending outward from at least one sidewall of the dust chamber, the at least one projection being configured to removably mate the housing to a cleaning device; and

a cleaning pad coupled to the housing and configured to contact a surface to be cleaned.

19. The replacement head of claim 18 , further comprising a filter extending across an opening of the housing, the filter being configured to allow a vacuum force to be applied to the dust chamber while retaining debris within the dust chamber.

20. The replacement head of claim 18 , wherein the cleaning sheet is directly attached to the housing.

21. The replacement head of claim 18 , wherein the cleaning sheet is planar.
