Abstract
A cleaner head comprising a main body rotatably coupled to a neck, and a locking arrangement operable to permit rotation of the main body relative to the neck when the cleaner head is positioned on a surface and to prevent rotation of the body relative to the next when the cleaner head is lifted off a surface. The locking arrangement therefore stops the cleaner head from rotating undesirably when the cleaner head is lifted away from a cleaning surface.
