Abstract
A vacuum cleaner is described. The vacuum cleaner has a dirt inlet and a motor and fan for delivering suction to the dirt inlet. A cyclone unit separates particles from a suction flow. The cyclone unit has a vortex finder extending along a cyclone axis of rotation and an annular chamber formed around outside of the vortex finder. Air is delivered to the cyclone unit in a forward direction (i.e. in a direction from the dirt inlet to the cyclone unit). The cyclone axis of rotation is substantially parallel to the forward direction. An outlet from the vortex finder is at a backward end thereof such that the outlet is in an opposite direction to a forward component. A space beyond the vortex finder is a part of a dirt collection area, thus enabling a more effective collection of hairs and other debris.
