Abstract
A cleaner head for a vacuum cleaner includes a body that defines a suction chamber, the suction chamber having a suction inlet for engaging a surface to be cleaned, and an outlet for fluid connection to a suction generator of a vacuum cleaner. The cleaner head further includes first and second brush bars each configured to contact a surface engaged by the suction inlet, and a drive mechanism which has an actuator. The drive mechanism is configured to rotate the brush bars about respective axes. The drive mechanism is also configured to rotate the first brush bar independently of the second brush bar, and to rotate the second brush bar independently of the first brush bar.
