Abstract
A method for identifying a brush type of a cleaning device includes: acquiring a detection voltage of a brush motor, the detection voltage being less than a starting voltage of the brush motor; acquiring a first impedance of the brush motor, in response to inputting the detection voltage to the brush motor; and determining a brush type corresponding to the brush motor based on the first impedance and a correspondence between impedances and brush types stored.
