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 . An apparatus comprising:
 a cleaning head configured to be removably attachable to a source of suction, the cleaning head having an upper side and a lower side, the lower side of the cleaning head arranged to contact a surface to be cleaned, and a dirt collection chamber permanently attached to the cleaning head; and   a suction nozzle being removably attachable to at least one of the cleaning head and the cleaning device.   
     
     
         2 . The apparatus of  claim 1 , wherein the cleaning head is arranged to hold a cleaning sheet on the lower side of the cleaning head. 
     
     
         3 . The apparatus of  claim 2 , wherein the cleaning sheet is permanently held to the lower side of the cleaning head. 
     
     
         4 . The apparatus of  claim 1 , wherein the cleaning head includes an inlet opening arranged to transfer dirt entrained air into the dirt collection chamber. 
     
     
         5 . The apparatus of  claim 1 , wherein the dirt collection chamber is positioned on the upper side of the cleaning head. 
     
     
         6 . The apparatus of  claim 1 , wherein the dirt collection chamber protrudes from the upper side of the cleaning head. 
     
     
         7 . The apparatus of  claim 1 , wherein each of the suction nozzle and the cleaning head are disposable. 
     
     
         8 . The apparatus of  claim 1 , wherein the suction nozzle is reusable and the cleaning head is disposable. 
     
     
         9 . A method of using a cleaning head, the cleaning head including a dust chamber, the method comprising:
 providing a cleaning head, the cleaning head including a dust chamber that is configured to be removably connected to a cleaning device;   attaching a suction nozzle to the cleaning head;   operating the cleaning device to move dirt through the first suction nozzle and into the dirt collection chamber;   removing the suction nozzle from the cleaning head; and   disposing of the first cleaning head.   
     
     
         10 . The method of  claim 9 , further comprising attaching a second cleaning head to the connector, the second cleaning head including a second dirt collection chamber. 
     
     
         11 . The method of  claim 10 , further including the step of attaching the suction nozzle to the second cleaning head. 
     
     
         12 . The method of  claim 11 , further including the steps of:
 operating the device to move dirt through the first suction nozzle and into the second dirt collection chamber;   removing the suction nozzle from the second cleaning head; and   disposing of the second cleaning head.   
     
     
         13 . A method as in  claim 9 , wherein the dirt collection chamber is permanently attached to the cleaning head. 
     
     
         14 . A method as in Tim  9 , wherein the cleaning head includes a support for a cleaning sheet.
