Abstract:
The present application relates to a vacuum cleaner head (10). The vacuum cleaner head (10) includes a housing (40) having a vacuum extraction zone (49), and first and second rollers (20, 30) configured to locate against a surface to be cleaned (60). Each of the first and second rollers (20, 30) is able to pick-up detritus from the surface to be cleaned (60) when they rotate and move over the surface (60) and to carry detritus to the vacuum extraction area (49) in the housing (40). In accordance with the present invention, the first roller (20) is rotatable when moved along the surface to be cleaned (60) in a first direction and restricted from rotating when moved in an opposing second direction. The second roller (30) is rotatable when moved along the surface to be cleaned (60) in the second direction and restricted from rotating when moved in the first direction. The present application also relates to a vacuum cleaner comprising the vacuum cleaner head (10).
