The bottom of a washing machine is provided with fixed feet and hydraulic feet, at least two fixed feet and at least one hydraulic foot form a supporting plane for supporting the washing machine; each hydraulic foot comprises a fixed part and a movable part, a hollow chamber is formed between the fixed part and the movable part, and the hollow chamber is provided with a hydraulic medium: the hydraulic medium flows under pressure in the hollow chambers to drive the movable parts to extend and retract; the hydraulic feet cooperate with the fixed feet to implement automatic leveling. The two fixed feet define two points, hydraulic feet define another point, so that even if the ground is uneven, the two fixed feet closely bear the weight of the washing machine, the hydraulic feet can automatically extend or retract according to the size of pressure, to implement automatic leveling.
