A vacuum cleaner (2) having a body (4) having a floorhead (6) and an elongate handle (14) pivotably mounted to the body is disclosed. A door (24) is provided on an end (20) of a collection chamber (12) opposite to a clean air outlet, and a coarse filter (32) and fine filter (46) are located within the collection chamber for separating out debris entrained with dirty air and depositing the debris in the collection chamber. An interior face of the door is provided with radial tangs (68), and an end face (48) of the fine filter is provided with radial tangs (60) such that when the door is closed and the elongate handle is pivoted relative to the body, the fine filter and coarse filter rotate relative to each other to cause cleaning of the filter elements.
