A power factor correction circuit, a power supply device and a vacuum cleaner using the same. The power supply device for a vacuum cleaner is applicable to a vacuum cleaner having a flexible hose. The power supply device for a vacuum cleaner includes: A power factor correction unit correcting a power factor of an AC voltage supplied from an AC power source; a rectifying unit rectifying the AC voltage power factor-corrected by the power factor correction unit into a direct current (DC) voltage and outputting the DC voltage; a smoothing unit smoothing the DC voltage output from the rectifying unit and outputting the smoothed the DC voltage; an a converting unit converting the smoothed DC voltage from the smoothing unit into an AC voltage, wherein the power factor correction unit uses a conductive line included in the flexible hose, as an inductor.
