Cleaning device

Abstract

Methods and apparatus for cleaning a surface with a cleaning device having a body with a handle, a connector, and one or more cleaning heads that are removably attached to the cleaning device. Each cleaning head include a lower surface arranged to contact a surface to be cleaned and a dirt collection chamber permanently attached to the cleaning head. The cleaning head may include a support structure to support the dirt collection chamber and a cleaning sheet. The cleaning head also may include a suction nozzle. At least a portion of the dirt collection chamber may be made of a filter material.

What is claimed is: 
     
         1 . A cleaning assembly, comprising:
 a cleaning device having a handle, a shaft extending from the handle, and a connector head;   a replacement head configured to removably mate to the connector head, the replacement head having housing with a suction inlet and a chamber configured to receive debris from the suction inlet, and a cleaning sheet coupled to the housing and configured to contact a surface to be cleaned, the housing and the connector head having substantially the same width.   
     
     
         2 . The cleaning assembly of  claim 1 , wherein the replacement head includes at least one engagement feature configured to mate with a corresponding engagement feature on the connector head of the cleaning device. 
     
     
         3 . The cleaning assembly of  claim 1 , wherein the replacement head includes a portion defining an opening and configured to couple to a vacuum source on the cleaning device to allow a vacuum force to be applied through the opening to the dirt collection chamber to draw debris into the dirt collection chamber. 
     
     
         4 . The cleaning assembly of  claim 3 , wherein the replacement head includes a filter extending across the opening for allowing a vacuum force to be applied to the dirt collection chamber while retaining debris within the dirt collection chamber. 
     
     
         5 . The cleaning assembly of  claim 1 , wherein an opening of the suction inlet is aligned with an edge of the cleaning sheet. 
     
     
         6 . The cleaning assembly of  claim 1 , wherein the cleaning device includes a spray nozzle thereon for delivering fluid to a surface to be cleaned. 
     
     
         7 . The cleaning assembly of  claim 1 , wherein the replacement head includes at least one engagement feature configured to mate with a corresponding engagement feature on the connector head of the cleaning device. 
     
     
         8 . The cleaning assembly of  claim 1 , wherein the cleaning device includes a release mechanism for releasing the replacement head from the cleaning device. 
     
     
         9 . The cleaning assembly of  claim 1 , wherein the cleaning sheet is directly attached to the replacement head. 
     
     
         10 . The cleaning assembly of  claim 1 , wherein the cleaning sheet is planar. 
     
     
         11 . A cleaning assembly, comprising:
 a cleaning device having a handle, a shaft extending from the handle, a body having a vacuum source, and a connector head; and   a replacement head configured to removably mate to the connector head, the replacement head including a dirt collection chamber therein for receiving and retaining debris, and a cleaning sheet for contacting a surface to be cleaned, wherein the cleaning sheet and the connector head having substantially the same width.   
     
     
         12 . The cleaning assembly of  claim 11 , wherein the replacement head includes a portion defining an opening and configured to couple to the vacuum source on the cleaning device to allow a vacuum force to be applied through the opening to the dirt collection chamber to draw debris into the dirt collection chamber. 
     
     
         13 . The cleaning assembly of  claim 12 , wherein the replacement head includes a filter extending across the opening for allowing a vacuum force to be applied to the dirt collection chamber while retaining debris within the dirt collection chamber. 
     
     
         14 . The cleaning assembly of  claim 11 , wherein the replacement head includes at least one engagement feature configured to mate with a corresponding engagement feature on the connector head of the cleaning device. 
     
     
         15 . The cleaning assembly of  claim 11 , wherein the cleaning sheet is directly attached to the replacement head. 
     
     
         16 . The cleaning assembly of  claim 11 , wherein the cleaning device includes a spray nozzle thereon for delivering fluid to a surface to be cleaned. 
     
     
         17 . The cleaning assembly of  claim 11 , wherein the cleaning sheet is planar. 
     
     
         18 . The cleaning assembly of  claim 11 , further comprising a release mechanism on the connector head for releasing the replacement head from the cleaning device.
