Abstract
An apparatus and method for transporting a flow of air and particulates through a vacuum cleaner. The apparatus can include a manifold with two inlet ports that collect two separate streams of the flow, combine the streams, and direct the combined flow toward a filter element through a single outlet port. The flow can expand within the manifold between the inlet ports and the outlet ports to decelerate the flow. The manifold can also include a storage receptacle for storing a belt used to drive a roller brush of the vacuum cleaner.
