Abstract:
A method for controlling a cleaning device is presented, which includes the following steps. A cleaning device includes a control unit, a fan module, an optical emitter, and an optical sensor. The optical emitter and the optical sensor are located in an air inlet of the fan module. The control unit is preset with a first impedance value (Z1), a second impedance value (Z2), and a threshold, where 0
