ABSTRACT:
A motor assembly for a vacuum cleaner for providing a user with a quieter environment during a cleaning work, and a vacuum cleaner having the same, is disclosed. The motor assembly includes a motor generating a suction force, an auxiliary filter member disposed on an airflow path connecting the motor to a dust-collecting apparatus for filtering a second time the air discharged from the dust-collecting apparatus, and a motor casing. The motor casing includes a first chamber connected to the dust-collecting apparatus with the auxiliary filter member mounted therein. A second chamber is connected to a discharge opening of the cleaner body and includes the motor mounted therein. A connection path is in fluid communication with the first chamber and the second chamber.
