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.
