<p>A vacuum cleaner is such that any rotary brush, dispensed with a quiet suction body is provided. Gaps (suction nozzles) are provided in a front edge of the suction body facing a surface being cleaned, and a suction chamber formed by a smooth, continuous surface of a cylindrical shape is provided to extend from an end of the suction nozzle into the suction body. Suction is effected in the suction chamber by suction means whereby a swirling air flow is generated in a longitudinal direction of the suction body to cause the high speed air flow to separate and such dust from the surface being cleaned.</p> |
