Floor mopping robot and water spray control method and apparatus and readable storage medium

A floor mopping robot, comprising:

• a first control unit, configured to control, in a first stage, a water spray system of the floor mopping robot to spray a first pre-set amount of water;
• and
• a second control unit, configured to control, in a second stage after the first stage, the water spray control system to spray a second pre-set amount of water,
• wherein, each of the first stage and the second stage is related to an out-of-station distance, an already cleaned area, or an already moved distance of the floor mopping robot,
• wherein the out-of-station distance is a distance that the floor mopping robot has moved away from a charging station since start-up, and
• wherein the second pre-set amount of water is less than the first pre-set amount of water.

A non-transitory computer-readable storage medium, which stores computer program instructions, when the computer program instructions are executed by a processor of a floor mopping robot, the instructions cause the processor to execute a water spray control method comprising:

• controlling, in a first stage, a water spray system of the floor mopping robot to spray a first pre-set amount of water;
• and
• controlling, in a second stage after the first stage, the water spray system to spray a second pre-set amount of water each time,
• wherein, each of the first stage and the second stage is related to an out-of-station distance, an already cleaned area, or an already moved distance of the floor mopping robot,
• wherein the out-of-station distance is a distance that the floor mopping robot has moved away from a charging station since start-up, and
• wherein the second pre-set amount of water is less than the first pre-set amount of water.
