    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.
