The present invention relates to a device for reducing impeller noise and vibration in a vacuum cleaner, which can significantly reduce the generation of severe noise and vibration due to air being rapidly suctioned in through an impeller, prevent noise pollution of the surroundings due to severe noise from the impeller of a vacuum cleaner, and alter air cavities between blades due to an increase in air suctioned in through the impeller of a vacuum cleaner, in order to reduce the noise from an impeller drive motor. |
