Abstract
An apparatus and method for transporting a flow of air and particulates through a vacuum cleaner. The apparatus can include an airflow propulsion device that draws the flow through an intake aperture and propels the flow through two upwardly-extending conduits toward a filter element housed in a filter housing. The conduits can have generally smooth internal walls and a combined flow area less than the flow area of the intake aperture to accelerate the flow upwardly toward the filter element.
