Abstract

An apparatus and method for transporting a flow of air and particulates through a vacuum cleaner. In one embodiment, the apparatus includes an intake body (100) having an intake opening (111) configured to receive the flow of air and particulates. An airflow propulsion device (200) is coupled to the intake opening (111) to draw the flow through the intake opening (111) and through a flow passage having an approximately constant flow area. The flow continues through one or more conduits (30) from the propulsion device (200) to a filter element (80) housed in a filter housing (70) where the particulates are separated from the flow of air.
