Abstract
A cleaner head for a vacuum cleaner includes: a body having a proximal end and a distal end; an agitator, an axis of rotation Rof the agitator being substantially parallel to a longitudinal direction of the body; a motor configured to cause the agitator to rotate; and a joint configured to turnably connect a suction pipe to the body. The joint is positioned closer to the proximal end than to the distal end. The body includes a second suction channel configured to communicate with a first suction channel inside the joint, and a bulkhead configured to separate an agitator chamber and the second suction channel from each other. The second suction channel extends substantially parallel to the axis of rotation of the agitator. The bulkhead includes at least one air vent from the agitator chamber to the second suction channel.
