Abstract

A vacuum cleaner (20) that includes a cyclone separator (38) has a coarse filter (F) disposed in the path of air flowing towards the outlet of the cyclone separator, for holding back hair that would otherwise tend to clog the vacuum cleaner (20), while minimizing impedance to air flow. In a preferred embodiment, the coarse filter (F) comprises a disc-shaped lattice structure of barrier elements (68) that are arranged to 'catch' the animal hair.
