Abstract: A reservoir device includes: a liquid storage structure, configured to store liquid; a liquid feeding assembly, configured to feed the liquid into the liquid storage structure; a barrier assembly; a sensing field generator, configured to generate a sensing field; a sensor; and an electrical control assembly. The barrier assembly is arranged inside the liquid storage structure. The sensor is configured to sense the sensing field. The barrier assembly is configured to float under a buoyance action of the liquid, and to block the sensor from sensing the sensing field when the barrier assembly floats in a first liquid level position. The electrical control assembly is configured to control the liquid feeding assembly to stop feeding the liquid into the liquid storage structure when the barrier assembly blocks the sensor from sensing the sensing field.

Abstract: The cleaning fluid supply system includes a first fluid storage device, a second fluid storage device, a pipeline assembly and at least one fluid drive device, and they are all mounted on the base. The pipeline assembly is provided with a main pipeline, a first branch and a second branch. The main pipeline is configured to supply the cleaning fluid to the cleaning robot. The first branch is communicated with the first fluid storage device, and the second branch is communicated with the second fluid storage device. The first branch and the second branch are both communicated with the main pipeline. The at least one fluid driving device is configured to drive the fluid in the first fluid storage device and the fluid in the second fluid storage device to flow to the first branch and the second branch, respectively.
