ABSTRACT:
Disclosed herein is a vacuum cleaner having a housing defining a blower port, an exhaust port, and a flow path between the blower port and the exhaust port. The vacuum cleaner also includes a removable cap assembly for the blower port to direct discharge airflow via the flow path to the exhaust port. The removable cap assembly, in turn, includes a cap head that engages the blower port to close the blower port, a cap body coupled to the cap head and inserted in the flow path, the cap body comprising a frame through which the discharge airflow passes, and a sound-influencing material supported by the frame within the flow path to reduce noise effected by the discharge airflow. The sound-influencing material may include a reticulated foam roll disposed in the frame to diffuse the discharge airflow.
