Abstract

A cyclone separator for a vacuum cleaner. The separator has a cyclone chamber, an air entrance device having a flow passage arrangement therethrough for introducing an air stream into the cyclone chamber in a manner that causes the air stream to swirl in the cyclone chamber to remove dust from the air stream, and an air outlet for emitting the air stream from the cyclone chamber. The entrance device has a control member that is operable to alter the flow passage arrangement such that one or more properties of the air stream in the cyclone chamber are affected by the alteration. The flow passage arrangement has a first path and a second path, and the control member is operable to alter the flow passage arrangement by redirecting the air stream from the first path to the second path.
