Abstract: A cleaner includes a brush device including a voltage detection circuit configured to measure a voltage applied to the brush device from a battery, a capacitor charged with the voltage applied to the brush device from the battery, an inrush current reduction circuit including a resistor configured to reduce an inrush current which occurs in charging the capacitor and a switching device used to control the inrush current, and a processor configured to turn off the switching device included in the inrush current reduction circuit based on a drop rate of the voltage measured through the voltage detection circuit being at least a threshold rate.
