Abstract
The invention provides a cleaner head assembly for a vacuum cleaner comprising 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 and a brush bar mounted therein, wherein the brush housing comprises a sealed unit connectable to a vacuum cleaner air inlet via a conduit separate from the cleaner head body. The arrangement allows the brush housing to be doubly articulated with respect to the main body of the vacuum cleaner whilst the suction opening remains in a horizontal plane without requiring the use of seals which must be able to accommodate the articulation of the brush housing.
