Disclosed herein is a method for determining a frequency of a power brush in a vacuum cleaner. According to the method of the present invention, a mechanical oscillation frequency of a driving unit, which includes a brush body reciprocated within a range of prescribed angles, and a torsion bar for providing a prescribed elastic force to angular rotation of the brush body, is set equally to a driving frequency of a power supply unit, which drives the driving unit, or is set a prescribed percentage higher or lower than the driving frequency of the power supply unit, so that the driving unit can resonate. A large amount of movement is obtained using a small amount of power by means of the resonance.
