Abstract: A suction unit includes a suction motor for generating air flow; a noise reduction unit which surrounds the suction motor and acts as a resonator in order to reduce noise generated during the operation of the suction motor; and a motor chamber which surrounds the noise reduction unit. The noise reduction unit includes an air flow path which provide a path of air flowing by the suction motor, a noise reduction chamber for eliminating the noise of at least one frequency band, and at least one communicating hole which causes sound wave of the noise to enter the noise reduction chamber. The air flow path is divided from the noise reduction chamber and thus the sound wave of the noise enters the noise reduction chamber through the communicating hole during a process in which air passes through the air flow path.

Abstract: Provided is a vacuum cleaner. The vacuum cleaner includes a cleaner body and a dust container separably mounted on the cleaner body. The dust container includes a dust collection body including a first chamber in which air and dust are separated from each other and a second chamber in which the dust separated in the first chamber are stored and a pressing member rotatably reciprocated between the first and second chambers within the dust collection body to compress the dust stored in the second chamber in one direction while moving from the first chamber to the second chamber.
