Abstract

The invention provides a cleaner head assembly for a vaccum cleaner comprising a cleaner head body (10) rotatably mountable on the main body (102) of a vacuum cleaner (100), a brush housing (110) rotatably mounted on the cleaner head body (10) and having a dirty air inlet (112), a dirty air outlet and a brush bar (26) mounted in the dirty air inlet (112), wherein the brush housing (110) has a projecting arm (30) carrying a cam follower (32) for contacting a cam surface (34) located on the main body (102) of the vacuum cleaner (100), the cam surface (34) being adapted to maintain the dirty air inlet (112) in a horizontal plane. This maintains good suction through the cleaner head during cleaning.
