Abstract
A cyclonic separator for separating particles and/or liquids from an airflow using means for causing the air to follow a cyclonic flow pattern through the separating chamber (12; 112; 212) and around an axis (17; 117) for causing cyclonic separation of a least a portion of the particles and/or liquids from the airflow within the separating chamber (12; 112; 212). An interior surface portion of a drum (18; 118; 218) bounding the separating chamber (12; 112; 212) and extending circumferentially around the axis (17; 117) is rotatable about the axis (17; 117) so that separation of particles and/or liquid from the airflow is improved. A vacuum cleaner including such a separator is also described.
