Abstract: A domestic appliance such as a cyclonic vacuum cleaner includes a component such as separating apparatus, carried by a chassis. A catch is provided and is operable to release the component from the chassis. The component and the chassis are able to move slightly with respect to each other. When the appliance is lifted, lugs on the separating apparatus move into slots on the chassis so as to inhibit release of the catch when the appliance is lifted. Thus, accidental release of the separating apparatus from the chassis is avoided.

Abstract: A filter housing includes an inlet for receiving airflow, a cavity for receiving a filter and an airflow passage between the inlet and the filter. At least one vane is positioned in the airflow passage for partitioning the airflow passage into a plurality of ducts. Each vane has a non-linear shape in the direction of flow through the airflow passage. This helps to reduce acoustic emissions from the machine since sound waves emitted by the fan and/or motor are caused to bounce off the vanes, which allows the vanes to absorb some of the sound energy. The filter housing can form part of a vacuum cleaner.
