After the cleaning robot 1 and the base station 2 are butted in place, the wiping part 12 enters the water tank 221, the wiping part 12 abuts against the cleaning ribs 2221 at the top of the cleaning structure 222, at the moment, the cleaning robot 1 drives the wiping part 12 to rotate towards the first direction, the cleaning structure 222 is locked by the ratchet structure, the cleaning part 12 can be rotated to automatically clean by scraping between the cleaning ribs 2221 and the fixed cleaning ribs 2221, meanwhile, the water spraying structure can convey cleaning liquid in the clean water tank 23 to the water tank 221 through the water spraying opening 24, the cleaning effect of the wiping part 12 is improved, and then sewage generated by cleaning can be pumped into the sewage tank 25 by a sewage pump to be stored. After the mop 12 rotates in the first direction for a while, the cleaning robot 1 drives the mop 12 to rotate in the second direction again, so that the cleaning structure 222 is driven by the mop 12 to rotate, the rotating cleaning structure 222 cleans the bottom wall of the water tank 221 by using the flexible part 2222 at the bottom, and meanwhile, the water spraying structure can deliver the cleaning liquid in the clean water tank 23 to the water tank 221 through the water spraying opening 24, on one hand, the flexible part 2222 scrapes off the dirt on the bottom wall of the water tank 221, on the other hand, the washing water sprayed from the water spraying opening 24 washes off the dirt on the water tank 221, and the washing water sprayed from the water spraying opening 24 carries the cleaned dirt to flow from the edge of the water tank 221 to the water suction opening 26 in the central area, and the water discharging structure pumps the dirt-carrying liquid into the dirty water tank 25 through the water suction opening 26, thereby cleaning the water tank 221. Alternatively, when the water tank 221 needs cleaning, the user may directly turn on the water spraying structure to flush the water tank 221. Alternatively, when the water tank 221 needs cleaning, the user actively calls the cleaning robot 1 back to the base station 2, and then makes the cleaning robot 1 drive the cleaning structure 222 to rotate, so that the water spraying structure cooperates with the flexible part 2222 to clean the water tank 221.
