Abstract: The invention relates to a cleaning apparatus (10) for releasing and transporting particles away from an area to be cleaned, comprising: a housing (6) having an opening (8) to be positioned on an area (1) to be cleaned;—a member that is movable within the apparatus for generating an airflow to release and transport particles away from the area; wherein the member comprises an airflow-generating surface (12) arranged within the housing (6), said airflow-generating surface in its operating condition lacing the area (1) to be cleaned and having a direction of movement that is substantially parallel to said area so as to cause an airflow parallel to said area. The apparatus according to the invention requires less energy for releasing and transporting particles away from an area to be cleaned.

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.
