A VACUUM CLEANING APPLIANCE

摘要

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 from a surface. The agitator assembly is housed in an agitator chamber housing including a downwardly-directed opening through which dust particles energised by the agitator enter the cleaner head, and a dust outlet located adjacent the opening and through which the energised 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 energised dust particles therebetween through collisions thereagainst until the energy of the energised dust particles has decreased to a level which enables the dust particles to become entrained within the air flow.
