A vacuum cleaner comprises a suction brush movably disposed at a lower portion of a cleaner body, a by-pass motor disposed in the cleaner body and generating a suction force at the suction brush, a cyclone dust-collecting apparatus disposed in the cleaner body and having an inflow passage, into which air passing by the by- pass motor flows, and an outflow passage through which the air cleaned by a separation effect of centrifugal force is discharged, and a dust bag disposed in the cleaner body and connected to the outflow passage for filtering minute dust entrained in the once cleaned air which is discharged from the cyclone dust-collecting apparatus.
