Abstract
A vacuum cleaner including a housing, a suction inlet, a suction source, a collector and a filtering unit. The housing includes a suction airflow through the housing. The suction source draws the suction airflow through the suction inlet. The collector receives debris separated from the suction airflow and is disposed between the suction inlet and the suction source. The filtering unit includes a filter, a retractable member, and a biasing member, where the retractable member is operable in directions towards and away from the filter for supplying momentary impact to the filter for providing agitations to rid the filter from debris. The biasing member urges the retractable member towards the filter.
