Patent ID: 7937804

Claim:
A vacuum cleaner comprising: a motor including a motor shaft; a roller brush; a drive belt coupled to the roller brush and the motor shaft to transmit rotary motion from the motor shaft to the roller brush; and a clutch mechanism including an idler pulley movable between a first position, in which the idler pulley is disengaged from the drive belt such that the drive belt transmits rotary motion from the motor shaft to the roller brush, and a second position, in which the idler pulley engages the drive belt such that the drive belt is decoupled from the motor shaft, and an actuator coupled to the idler pulley to move the idler pulley, the actuator being actuated by a user in a direction to move the idler pulley from the first position to the second position and being actuated by the user in the same direction to move the idler pulley from the second position to the first position, wherein the actuator is depressed by the user to move the idler pulley from the first position to the second position, and wherein the actuator is also depressed by the user to move the idler pulley from the second position to the first position, and wherein depressing the actuator rotates the actuator, wherein the actuator is rotated less than 45 degrees by the user to move the idler pulley from the first position to the second position, and wherein the actuator is rotated less than 20 degrees by the user to move the idler pulley from the second position to the first position.
