Abstract:
A vacuum cleaner includes at least one cyclone dust separation unit. A cover is formed over the cyclone dust separation unit to attenuate noise generated by the cyclone unit. Dimples or recesses may be formed on the interior of the cover to further attenuate noise. In addition, a noise attenuating material may be inserted between the cyclone dust separation unit and the cover.
