Abstract: A cleaner head includes an agitator; a housing defining an agitator chamber and an aperture through which the agitator can be removed from the agitator chamber; and an end cap attachable to the housing to close the aperture, and releasable from the housing to open the aperture. The end cap is attachable and releasable by rotating at least a locking portion of the end cap about a locking axis between locked and unlocked positions relative to the housing. The cleaner head has a latch mechanism configured to prevent rotation of the locking portion to the unlocked position. The latch mechanism has a release member which is provided on the end cap, the release member being operable by hand to release the latch.
