Abstract
A dirt detection method includes the steps of: selecting a motor with a motor processor, and then using the motor to provide power to form a negative pressure to suck the dirt into the dirt collection device, the motor processor sending the motor's operating signal to the detection processor that has written therein a threshold range for detection, and then comparing the threshold range with the operating signal from the motor processor. The invention is based on the motor as the power source of negative pressure, and the dirt collection device has good collection effect and sealing. Based on the equipment characteristics of the motor in the negative pressure system, the degree of dirt in the dirt collection device is detected by detecting the operating signal of the motor.
