Abstract:
A cleaner head for a vacuum cleaning appliance includes a main body having a downwardly-directed suction opening and at least one surface engaging support member, a front agitator and a rear agitator, with each agitator being rotatable relative to the main body, and a mechanism for rotating the front agitator and the rear agitator. The front agitator has a relatively flexible pile and the rear agitator has relatively stiff bristles arranged to dislodge matter from the pile of the front agitator. The pile of the front agitator and the at least one surface engaging support member extend downwardly beyond the bristles of the rear agitator so as to space the bristles of the rear agitator from a relatively hard surface to be cleaned.
