Abstract
A cyclone bin assembly comprises a cyclone chamber having an air inlet, an air outlet, a dirt outlet and first and second opposed ends. The cyclone bin assembly may comprise a dirt collection chamber in communication with the dirt outlet. The dirt bin may surround at least a portion of the cyclone chamber and comprising first and second portions. The first and second portions may comprise discrete chambers that are separated from each other by a passage extending between the dirt outlet and a wall of the dirt collection chamber. A portion of the wall facing the dirt outlet may extend inwardly towards the dirt outlet.
