- a rotatable agitator assembly;
an agitator chamber housing the agitator assembly;
a sole plate defining a downwardly-directed opening through which debris energized by the agitator assembly enters the agitator chamber, the opening having a front edge and a rear edge, the sole plate having a leading section extending forwardly from the front edge of the opening and a trailing section extending rearwardly from the rear edge of the opening; and
at least one support member located on each section of the sole plate, the support members extending downwardly beyond the sole plate, the support members having a thickness which is less than 5 mm;
wherein the lowermost extremities of the support members are located in a first plane and the edges of the opening are located in a second plane which is inclined upwardly relative to the first plane, and the agitator assembly comprises agitating members which extend outwardly from the opening beyond the second plane but within the first plane.

Abstract
A cleaner head for a cleaning appliance includes a rotatable agitator assembly, an agitator chamber housing the agitator assembly, and a sole plate defining a downwardly-directed opening through which debris energized by the agitator assembly enters the agitator chamber. A set of support members is located on a leading and trailing section of the sole plate, the support members extending downwardly beyond the sole plate to support the sole plate above a relatively hard floor surface. The lowermost extremities of the sets of support members are located in a first plane, and the edges of the opening are located in a second plane which is inclined upwardly relative to the first plane. The agitator assembly includes agitating members which extend outwardly from the opening beyond the second plane but within the first plane.
