摘要： A pool-cleaning robot is provided, comprising: a robot body with a moving mechanism controlled to move the robot body forward or backward; wherein the robot body has a weight difference between its left and right sides; the moving mechanism includes a driver to drive the moving mechanism unilaterally; the robot body is provided with a fluid inlet-outlet, at least one first fluid inlet, and at least one first fluid outlet, which are communicated with each other. The fluid inlet-outlet is provided with a fluid driver that applies a suction force to the first fluid inlet or a discharge force to the first fluid outlet; a controller in the robot body, connected to and controlling the operation of the moving mechanism and the fluid driver; when the robot body is on a floor or walls of a pool, combinations of discharge forces, suction forces and weight differences steer the robot.
