Abstract

A cleaner head or nozzle unit for a vacuum cleaning appliance includes a main body (12, fig 1) having a downwardly-directed suction opening and at least one surface engaging support member 52, 56, a front agitator 60 and a rear agitator 62, with each agitator 60, 62 being rotatable relative to the main body (12, fig 1), and a means for rotating the front agitator 60 and the rear agitator 62. The front agitator 60 has a relatively flexible pile and the rear agitator 62 has relatively stiff bristles arranged to dislodge matter from the pile of the front agitator 60. The pile of the front agitator 60 and the at least one surface engaging support member 52, 56 extend downwardly beyond the bristles of the rear agitator 62 so as to space the bristles of the rear agitator 62 from a relatively hard surface to be cleaned.
