The main body separates dust from the air using centrifugal force, collects the dust, and discharges the air to the suction nozzle unit. The air discharged from the main body flows through the suction motor, is ejected from the injection path toward the surface to be cleaned, and is then suctioned into the inlet so that a portion of the discharged air circulates within the vacuum cleaner.
