Abstract
A vacuum cleaner with a cyclone module assembly comprises a cyclone separation chamber for separating dust and debris from air and a collection chamber for collecting dust and debris that is separated from the air in the cyclone separation chamber. The cyclone module assembly further includes at least one feature for directing contaminants downwardly, such as a helical step dividing the separation chamber from the collection chamber or a circumferential fin that extends from the inside wall of the collection chamber.
