Abstract

A vacuum cleaner includes a cyclonic chamber having an inlet for introducing airflow for circulation around a central axis of the cyclonic chamber. A filter chamber is positioned downstream of the cyclonic chamber and has a wall. A filter is positioned in the filter chamber. An exhaust tube extends along the central axis into the cyclonic chamber. The exhaust tube includes an inlet portion receiving the airflow from the cyclonic chamber and an outlet portion directing the airflow toward the filter chamber and the filter. The filter is in close proximity to the outlet portion. The cross-sectional area of the outlet portion increases in the downstream direction to reduce the speed of the airflow passing into the filter chamber and to evenly distribute the airflow passing through the outlet opening across the filter.
