Abstract
A cleaner head for a vacuum cleaner has a housing, an agitator mounted within the housing, and a drive mechanism for driving the agitator about a first axis A. The drive mechanism is mounted to the housing for rotation about a second axis R. The second axis R is offset from the first axis A. When the agitator is brought into contact with a surface to be cleaned, the surface exerts a reaction torque on the agitator that causes the drive mechanism to rotate about the second axis R.
