摘要：
A cleaner head for a vacuum cleaning appliance includes a housing, a front agitator and a rear agitator. A suction chamber is located between the front agitator and the rear agitator. A baffle is located within the suction chamber between the agitators. During use of the cleaner head, debris becomes entrained within air drawn towards the suction chamber. Guide members mounted on the housing guide the entrained debris towards the suction chamber, whereas the baffle guides the air upwardly towards a central suction port of the suction chamber.
