Method for detecting working ground of cleaning equipment and cleaning equipment

The invention provides a method for detecting the working ground of cleaning equipment. The method comprises the steps: emitting millimeter waves to the working ground; receiving millimeter wave echoes reflected from the working ground and obtaining echo information; judging the ground type of the working ground according to the echo information; and controlling the cleaning equipment to operate in a preset mode according to the ground type. The invention further provides cleaning equipment. Millimeter waves are emitted to the working ground to determine the ground type, then the cleaning equipment is controlled to operate in the corresponding preset mode according to the ground type, and compared with traditional ultrasonic and laser detection, due to the fact that the millimeter waves have high penetrating capacity on dust, rain, fog and the like and are not interfered by light, the detection process is more stable. The cleaning equipment can adapt to an outdoor severe environment, so that the ground enviro
