Claim:
A surface cleaning apparatus comprising: (a) an air flow passage extending from a dirty air inlet to a clean air outlet; (b) a cyclone positioned in the air flow passage and having a cyclone air inlet and a cyclone air outlet at one end of a cyclone chamber, a dirt outlet spaced from the cyclone air inlet, a cyclone chamber wall and a centrally positioned longitudinal axis; (c) a dirt collection chamber in communication with the dirt outlet and having an openable wall moveably mounted to the surface cleaning apparatus and a centrally positioned longitudinal axis, the openable wall having a centre and a mounting side; (d) a plate moveably mounted between a closed position in which the plate is positioned at an interface of the dirt collection chamber and the cyclone and an open position in which the plate is moved away from the interface, the plate is moveably connected to the openable wall so that as the openable wall moves from a closed position to an open position, the plate is moved to the open position regardless of the orientation of the cyclone and the orientation of the plate moves to a different orientation with respect to the openable wall; (e) a biasing member biasing the plate towards the mounting side of the openable wall; and, (f) a suction motor positioned in the air flow passage.
