One end of the first branch line 232 is fixedly connected to the first drain port 13 and communicates with it. The second branch line 233 is connected to the second drain port 14 and communicates with it. When the first cleaning tank 21 is attached to the base 10, the first drain port of the first cleaning tank 21 and the first drain port 13 are connected to each other, and when the second cleaning tank 22 is attached to the base 10, the second drain port of the second cleaning tank 22 and the second drain port 14 are connected to each other.

[0030] The first fluid drive unit 124 and the second fluid drive unit 224 may operate independently. A first flow rate output from the first cleaning tank 21 to the first branch line 232 may be adjusted by adjusting an operating parameter of the first fluid drive unit 124. A second flow rate output from the second cleaning tank 22 to the second branch line 233 may be adjusted by an operating parameter of the second fluid drive unit 224. Since both the first flow rate and the second flow rate are adjustable, the blending ratio of the cleaning liquid supplied from the cleaning liquid supply system 20 can be freely adjusted, and more diverse cleaning demands can be met.

[0031] For example, one of the first cleaning tank 21 and the second cleaning tank 22 stores clean water, and the other stores a cleaning agent. By setting the operation parameters of the first fluid drive unit 124 and the second fluid drive unit 224, the first flow rate and the second flow rate can be adjusted, respectively, so that the maintenance station 100 can actively adjust the blending ratio of clean water and detergent supplied from the cleaning liquid.

[0038] In other embodiments, the control circuit board 30 controls only a single fluid driver 24 to provide fluid delivery.

[0039] In some embodiments, a user may set predetermined cleaning liquid demand information in a software interface of an intelligent terminal (such as a smartphone, smart tablet, or laptop), and the predetermined cleaning liquid demand information may include any one or a combination of a cleaning liquid demand amount, a cleaning liquid blending ratio, and cleaning demand, and may be transmitted to the cleaning robot 200 via a wireless network.

The cleaning robot 200 includes a water volume detection device 41 that detects the water volume state of the cleaning container 37, and the cleaning robot 200 determines the predetermined cleaning liquid demand information based on a detection signal of the water volume detection device 41. For example, when the water volume detection device 41 detects that the cleaning container 37 is in an anhydrous state, the cleaning robot 200 can determine that the refill amount of cleaning liquid in the predetermined cleaning liquid demand information is the capacity of the cleaning container 37, and when the water volume detection device 41 detects that the cleaning container 37 is in a half-full state, the cleaning robot 200 can determine that the refill amount of cleaning liquid in the predetermined cleaning liquid demand information is half the capacity of the cleaning container 37.
