Abstract
A surface cleaning apparatus comprises an air flow passage extending from a dirty air inlet to a clean air outlet. A suction motor is positioned in the air flow path. At least one cyclone chamber is positioned in the air flow passage. An associated dirt collection chamber is exterior to the cyclone chamber. The cyclone chamber and the suction motor are positioned side by side and have generally parallel longitudinal axes. The dirt collection chamber may surround part of the suction motor. Alternately, or in addition, a pre-motor filter having an enhanced surface area may be provided by configuring the pre-motor filter to extend outwardly of the pre-motor filter, such as by overlie part of the cyclone chamber or the dirt collection chamber.
