<p>The present invention relates to a foreign substance separating device using cyclone filtering. According to the present invention, when a mixture of foreign substances and water, separated from air in a suction, flows into a cyclone dust collector, the foreign substances are deposited by a centrifugal force while the mixture in the cyclone dust collector is forced back into the suction again to maintain the inflow amount of the mixture at a proper level, thereby preventing the mixture including the foreign substances from flowing backward.</p> |
