A vacuum cleaner that includes a suction motor and a filter assembly. The filter assembly surrounds at least part of the suction motor and has a frame to which a filter medium is attached. The filter medium is spaced from a wall of the frame such that an arcuate passageway is defined between the filter medium and the frame. A part of the air expelled by the suction motor enters a first end of the passageway and moves around the passageway in a clockwise direction. A further part of the air expelled by the suction motor enters a second end of the passageway and moves around the passageway in a counter-clockwise direction. Air within the passageway then passes through the filter medium.
