Abstract
A cyclone separator useable in a surface cleaning apparatus comprises a cyclone casing defining a cyclone chamber and having first and second opposed ends and a sidewall extending between the first and second ends. The first end is provided with a fluid inlet and the second end is provided with a dirt outlet. The dirt outlet provides a lateral outlet to a dirt collection chamber in communication with the cyclone chamber via the dirt outlet. The dirt outlet is positioned from about 90 to about 330° around the cyclone casing in a flow direction from the fluid inlet.
