ABSTRACT:
A vacuum power head is provided which has a bare floor feature. A vacuum cleaner head assembly defines a vacuum chamber which contains a power driven rotary brush. Located outside of the vacuum chamber adjacent the rotary brush is a generally U-shaped trailing brush. The trailing brush cooperates with a height adjustment mechanism which is movable between a deep carpet position and a bare floor position. As the height adjustment mechanism of the head assembly is moved toward the bare floor position, the trailing brush is automatically moved to an extended position into engagement with the floor. When the height adjustment mechanism is moved from the bare floor position, a spring biases the trailing brush toward a retracted position within the head assembly. An actuator cooperates with the height adjustment mechanism to automatically move the trailing brush between the retracted position and the extended position in response to movement of the height adjustment mechanism.
