A vacuum cleaner (1) includes a motor-driven blower (4) for drawing air and a dust-catching unit (15) for separating dust from the air drawn by the blower (4) and catching the dust separated from the air. A receptacle (23) is located between the blower (4) and the dust-catching unit (15) and holds a filter (61) for filtering the air that has passed through the dust-catching unit (15). An airflow control device (111) is arranged between the filter (61) and the blower (4). The airflow control device (111) generates a first airflow, which passes through the dust-catching unit (15) and the filter (61) and goes toward the motor-driven blower (4). The airflow control device (111) generates a second airflow, too, which bypasses the filter (61), passes through at least a part of the dust-catching unit (15), and goes toward the motor-driven blower (4). The part of the dust-catching unit (15) is located downstream of the receptacle (23), with respect to a direction in which the second airflow goes.
