Abstract

A cleaner head assembly for a vacuum cleaner includes a cleaner head body pivotably attachable to a main body of a vacuum cleaner and a brush housing pivotably mounted on the cleaner head body, the brush housing having a suction opening, a brush bar mounted therein and a resilient member provided to bias the brush housing in a pivoting direction so as to urge a rear portion of the brush housing in an upward direction with respect to the cleaner head body. This configuration allows the brush housing to be doubly articulated with respect to the main body of the vacuum cleaner as it is biased by the resilient member in the pivoting direction such that the rear portion of the brush housing is urged in an upward direction with respect to the cleaner head body and the suction opening remains in a horizontal plane.
