  • Publication number: 20110115638
    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<Z1<Z2. Then, the control unit reads an impedance value (Z) of the fan module. If Z1<Z<Z2, the control unit drives the fan module. If Z2<Z, the control unit reads a detected value of the optical sensor. If the detected value exceeds the threshold, the control unit drives the fan module, so as to increase a suction force of the fan module. If the detected value is smaller than the threshold, the control unit turns off the fan module.
