Abstract
A vacuum cleaner head having a casing having a dirty air inlet, a housing mounted above the dirty air inlet and moveable with respect to the dirty air inlet and a brush roatably mounted within the housing. The brush is moveable with the housing for improving the air flow of the dirty air around the brush into the vacuum cleaner head.

22. A method of cleaning a surface using a vacuum cleaner head comprising:
-
(a) providing a vacuum cleaner head having a casing with a dirty air inlet, a housing movably mounted within the casing, a brush movable mounted within the housing and an air flow path extending from the dirty air inlet to a source of suction;
(b) moving the vacuum cleaner head over the surface;
(c) entraining dirt on the surface into an air stream to form a dirty air stream which enters the dirty air inlet;
(d) passing the dirty air stream form the dirty air inlet into the housing;
(e) adjusting the position of the housing with respect to the dirty air inlet to allow for aerodynamic air flow around the brush, whereby the surface is cleaned. - View Dependent Claims (23)
