  • Apparatus for dampening the noise of a vacuum cleaner
    Patent number: 6804857
    Abstract: An improved vacuum cleaner has an acoustic dampening mechanism to substantially reduce the noise level generated from a suction unit of the vacuum cleaner while it is sufficiently cooled. Noise that radiates from the motor is continually sucked back into the motor and in effect, the noise is bent by using suction so that the noise is muffled by being pulled back into the motor.
