Abstract
Disclosed is a vacuum cleaner including a flow path to guide air suctioned or discharged and a resonator connected to the flow path. The resonator is configured to change a resonance frequency to be canceled. Therefore, when the noise generated by changing operation modes of the vacuum cleaner is changed, the noise may be cancelled by changing the resonance frequency of the resonator.
