Abstract: A cleaner head that includes a suction inlet for admitting a first airflow, a turbine inlet for admitting a second airflow, an outlet for discharging the first airflow and the second airflow and an agitator and its drive assembly. A first airflow path then carries the first airflow from the suction inlet to the outlet, and a second airflow path carries the second airflow from the turbine inlet to the outlet. The drive assembly includes a turbine that is driven by the second airflow. A baffle is located in the second airflow path and is movable between an open position in which the second airflow path is unrestricted and a closed position in which the second airflow path is restricted. The baffle is biased in the open position and moves to the closed position when the dynamic pressure of the second airflow at the baffle exceeds a threshold.

Abstract: A cleaner head comprising a main body rotatably coupled to a neck, and a locking arrangement operable to permit rotation of the main body relative to the neck when the cleaner head is positioned on a surface and to prevent rotation of the body relative to the next when the cleaner head is lifted off a surface. The locking arrangement therefore stops the cleaner head from rotating undesirably when the cleaner head is lifted away from a cleaning surface.
