| Zusammenfassung: | The invention provides a cleaning device and a detection method thereof. The cleaning device comprises a dust absorption fan, a drive motor, an impedance detection device and a control unit, wherein the drive motor drives the dust absorption fan to absorb dust; the impedance detection device is electrically connected with the drive motor and is used for detecting the impedance of the drive motor;the control unit is electrically connected with the drive motor and the impedance detection device; and when the impedance value detected by the impedance detection device is greater than a set value, the control unit controls the drive motor to stop driving the dust absorption fan. |
