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 () and around an axis () for causing cyclonic separation of a least a portion of the particles and/or liquids from the airflow within the separating chamber (). An interior surface portion of a drum () bounding the separating chamber () and extending circumferentially around the axis () is rotatable about the axis () so that separation of particles and/or liquid from the airflow is improved. A vacuum cleaner including such a separator is also described.
