Patent abstract

A cyclonic vacuum cleaner includes a body portion, a nozzle portion and a dirt cup which is removable from the body portion. The dirt cup collects dirt and other debris separated by a cyclone and a cyclone slinger portion in the body portion. A main filter may be housed in a transparent filter door downstream of the cyclone. The dirt cup may be inserted into and sealingly held within the body portion by using a rotational camming structure.
