PROBLEM TO BE SOLVED: To efficiently and effectively utilize water so as to eliminate fine dust, pollen, and even yellow sand. SOLUTION: Cellulose sponge having excellent water holding property holds water, and the water is guided by a fiber net to be properly taken into an urethane cloth dust filter. By synergy effects of energy of water molecules and suction force of a motor, dust is sucked as if it is attracted to a strong magnet. The thick urethan sponge makes a dense dust filter by collection of dust contained in numberless bubbles with improved fineness, so that dust or the like is completely eliminated. By using the vacuum cleaner for 10 minutes or a little longer, air is cleaned, and room air becomes clear and comfortable as if the room is ventilated. Suction force is doubled by means of urethane having excellent permeability. The burden of the motor is reduced to save power. It is especially suitable for use in hospitals, schools, elderly people's homes, etc., where many people stay together. COPYRIGHT: (C)2008,JPO&INPIT
