    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.

    Abstract: A vacuum cleaner including a suction inlet that provides entrance of a suction airflow, a suction source, a diffuser, a blower port, a duct, and a removable cap. The diffuser is in fluid communication with the suction source for diffusing the suction airflow and the diffuser includes a circumferential opening that surrounds the suction source such that the suction airflow travels through the opening into the diffuser. The duct is located downstream of the blower port with respect to the direction of the suction airflow and the duct includes an outlet. The cap is removably coupled to the blower port such that at least a portion of the suction airflow exhausts through the blower port when the cap is removed, and when the cap is coupled to the blower port the suction airflow is travels through the duct and exhausts through the outlet.
