Abstract: Disclosed herein is a vacuum cleaner having a housing defining first and second ports. The vacuum cleaner also includes a cap assembly. The cap assembly includes a cap head to close the first port such that airflow is directed via a flow path to the second port, a sound-influencing material, the sound-influencing material removably held to the cap head and disposed within the flow path to reduce noise effected by the airflow. The flow path is configured to cause the airflow to pass through the sound-influencing material and the flow path to the second port. The sound-influencing material is removable to allow cleaning of the sound-influencing material. The sound-influencing material may include a reticulated foam roll disposed in the frame to diffuse the discharge airflow.

Abstract: A cart comprising a first support structure supported on wheels. A second support structure is connected to the first support structure. The second support structure is movable relative to the first support structure between a first extended position and a second retracted position. A collapsible container is supported by the second support structure. The container occupyies a first extended position when the second support structure is in the first position and a second collapsed position when the second support structure is in the retracted position.

Abstract: A pneumatic cleaner that can be worn as a backpack has a reduced unit overall depth. The impeller shaft is mounted at an acute angle. Tangential airflow chambers are disposed around the motor assembly and substantially surround the impeller. Two of the airflow chambers extend substantially the entire overall unit depth, and have lateral lengths that exceed the overall unit depth.

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.

Abstract: A manual sander vacuum attachment, providing edge sanding and multiple positioning capabilities, having a lower sanding backer plate member, which carries a soft sanding pad and secures the sandpaper sheet, and an upper housing portion, having a generally horizontal platform with two vertically-extending stanchion supporting a handle therebetween, with a vacuum fitting for connection to a hose for a vacuum air source, and a peripheral skirt surrounding the backer plate member, whereby all vacuum air flow of sanded debris travels about periphery of sander backing plate up into interior of the housing portion.
