Abstract
The present invention provides a vacuum cleaner having an inlet (26) for dirty air, an outlet (24) for clean air, and a filter (44) located in fluid communication between the inlet and the outlet. A motor drives a fan for moving air into the inlet and through the filter to the outlet. A filter cleaning mechanism for removing dirt from the filter is provided and is operatively associated with an on/off switch for the fan motor or alternatively a separate user-operated switch, whereby operation of the switch results in operation of the filler cleaning mechanism.
