Zusammenfassung:A vacuum may include a housing defining a suction inlet opening and a debris chamber in communication with the suction inlet opening, a suction device disposed in the housing for providing a vacuum pressure to the inlet opening, a filter disposed in an airflow path between the suction inlet opening and the suction device, and a motor driving a device for disengaging debris from the filter. The device for disengaging debris from the filter may include at least one finger disposed on a belt or a rake.
