Surface cleaning apparatus

A surface cleaning apparatus comprising an air flow path extending from a dirty air inlet to a clean air outlet with a cyclone and a suction motor positioned in the air flow path, the cyclone comprising:

• (a) a cyclone chamber having a longitudinally extending cyclone axis of rotation, a first end, an opposed end spaced apart in a longitudinal axial direction from the first end, a tangential air inlet located at the first end, a cyclone air outlet located at the opposed end, a dirt outlet and a tapered screen member;
• and,
• (b) a dirt collection chamber exterior to the cyclone chamber and in communication with the cyclone chamber via the dirt outlet, the dirt collection chamber extending around at least 50% of an outer perimeter of the cyclone chamber,
• wherein the tangential inlet has an inlet width extending in the longitudinal axial direction from a first side to a second side spaced apart in a longitudinal axial direction from the first side wherein the second side of the tangential inlet is axially inwardly closer to the opposed end than the first side of the tangential inlet is to the opposed end, and
• wherein the screen member has an outlet end located at the opposed end of the cyclone chamber and extends to distal screen end located adjacent the second side of the tangential inlet, the screen member tapers from the outlet end of the screen member to the distal screen end.
