Abstract

The invention relates to a vacuum cleaner head (10) for a vacuum cleaning appliance. The vacuum cleaner head (10) comprises a body (12) supporting an agitator (36). The agitator (36) includes a rotatable cylindrical body (42) with an elongate agitator structure (44) for engaging a floor surface upon rotation of the cylindrical body (42). The elongate agitator structure (44) comprises a first agitator row (46) extending around the cylindrical body (42) in a first helical direction from a respective first edge L of the cylindrical body (42) towards a center C thereof, and a second agitator row (47) extending around the cylindrical body (42) in a second helical direction, a second agitator row (47) extends from a respective second edge R of the cylindrical body (42) towards a center C thereof in a second helical direction opposite the first helical direction, where the first agitator row (46) comprises agitators of the first material and the second agitator row (47) comprises agitators of a second material different from the first material.

Description

technical field [0001] The present invention relates generally to vacuum cleaners and in particular to a cleaner head or floor implement forming part of a vacuum cleaner. The invention particularly relates to rotationally driven agitators for use in such cleaner heads, whether the cleaner heads are permanently or removably fixed to the respective vacuum cleaner. The type of vacuum cleaner is not important for the invention, so the invention may relate to so-called bagged or bagless vacuum cleaners. Background technique [0002] Vacuum cleaning appliances, or more simply "vacuum cleaners", generally comprise a main body equipped with a suction source and a dust separator, wherein the cleaner head is usually connected to the dust separator by a detachable coupling. The cleaner head has a suction inlet through which the cleaner head engages the surface to be cleaned and through which dust laden air is drawn into the vacuum cleaner towards the dust separator. The cleaner head ...
