Abstract
A cleaner head is described for use with a vacuum cleaning appliance including a fan unit for generating an air flow which passes from the cleaner head to the fan unit. The cleaner head includes a rotatable agitator assembly including an agitator for sweeping dust particles. The agitator assembly is housed in an agitator chamber housing including a downwardly-directed opening through which dust particles energized by the agitator enter the cleaner head, and a dust outlet located adjacent the opening and through which the energized particles leave the agitator chamber. The cleaner head also includes an exhaust port from which a dust-bearing air flow is drawn from the cleaner head, and a dust channel extending between the dust outlet and the exhaust port. The dust channel has channel walls which are shaped to retain energized dust particles therebetween through collisions thereagainst.
