Abstract
A cleaner head (6) for a hard floor cleaner (2), the cleaner head (6) is provided. The cleaner head (6) comprises an elongate roller (10), a helical screw (22), a carrier head (25), and a contact member (40). The elongate roller (10) is configured to rotate about a roller axis (16) and the helical screw (22) is configured to rotate about a screw axis (26), the screw axis (26) being offset from the roller axis (16). The carrier head (25) is mounted to the helical screw (22) and is configured to travel along the screw axis (26 ) as the helical screw (22) rotates. The contact member (40) extends from the carrier head (25) and is arranged to contact an outer surface of the roller (10) so as to push debris (18) located on the outer surface towards an end (12b) of the roller (10).
