A cleaning robot, includes a body provided with a dust box, a water tank, a cleaning unit disposed at a bottom of the body, a water outlet mechanism outputting liquid in the water tank through the water discharge pipeline and a water discharge pipeline independently disposed outside the water tank and at least partially located directly below the dust box, so that the capacity of the water tank is increased, without requiring adding water frequently, thereby prolonging the time of operation, the layout of various parts in the body is more compact and feasible, a longer water discharge pipeline enables the corresponding cleaning unit to be made larger, by which a working area of the robot is expanded and the working efficiency is enhanced, the probability for damage is reduced, and the service life of the machine is prolonged.
