1. A vacuum cleaner comprising:
(a) an air flow path extending from a dirty air inlet to a clean air outlet;
(b) a cyclone assembly comprising a cyclone provided in the air flow path and a dirt collection region that is external to the cyclone chamber, the cyclone comprising a cyclone chamber, a cyclone air inlet, a cyclone air outlet, a dirt outlet, a central longitudinally extending axis, the cyclone chamber having first and second axially opposed ends and a cyclone sidewall extending between the first and second axially opposed ends;
(c) a suction motor positioned in the air flow path; and,
(d) a plate positioned at the second end of the cyclone chamber, the plate is moveably mounted between a closed position, in which the plate is positioned for operation of the cyclone and an open position wherein the plate is moved to provide access to the cyclone chamber,
wherein, when the plate is in the closed position, the plate has a cyclone chamber face that faces the cyclone chamber, the cyclone chamber face having first and second portions, and
wherein, when the plate is in the closed position, the first portion of the cyclone chamber face is spaced a first axial distance from a transverse plane that extends through the cyclone chamber and that is perpendicular to the central longitudinally extending axis of the cyclone, the second portion of the cyclone chamber face is spaced a second axial distance from the transverse plane, and the cyclone chamber sidewall has an end face that faces axially away from the first end of the cyclone and the end face is spaced a third distance from the transverse plane, wherein the second distance is larger than the first and third distances whereby the dirt outlet comprises a gap between the second portion of the cyclone chamber face and the end face of the cyclone chamber sidewall.
