Vacuum cleaner with electronic agitator control |
摘要 |
A vacuum cleaner includes a floor engaging portion and a handle portion pivotally mounted to the floor engaging portion. The handle portion includes an input device. An agitator is rotatably mounted in the floor engaging portion to agitate a floor surface being cleaned. A first motor has an output shaft and an agitator belt selectively drivingly connecting the motor to the agitator. A tensioning arm pivotally mounts to the floor engaging portion for motion between an agitator-on position in which the tensioning arm engages the agitator belt, to place the agitator belt under tension whereby the agitator belt drives the agitator, and an agitator-off position in which the tensioning arm does not engage the agitator belt, to place the agitator belt in a slack condition whereby the agitator belt does not drive the agitator. A lifting assembly is mounted in the floor engaging portion and includes a second motor and an engaging member driven by the second motor, the engaging member being adapted to contact the tensioning arm to selectively place the tensioning arm in the agitator-off position.
