News editors obtained the following quote from the background information suppli ed by the inventors:““Field of Invention“The present invention relates to a liquid replacement device and a cleaning sys tem, and more particularly,to a liquid replacement device and a cleaning system capable of replacing liquid.“Description of Related Art“It has become a trend to use self-propelled cleaning devices that can move auto nomously on a surfaceto be cleaned for cleaning places to be cleaned with large areas, such as commercial offices, factories, etc., asdisclosed in China Paten t No. CN112754370B titled “Robot Automatic Floor Washing Equipment.” Therobot a utomatic floor washing equipment includes a service station and a robot floor wa shing machine.The service station is provided with a water inlet pipe. One end of the water inlet pipe is connected to anexternal water source, such as a tap water service pipe, and the other end is equipped with a water faucet,which ext ends outward from a front side of the service station. The service station is fu rther equippedwith a sewage pipe. One end of the sewage pipe can extend vertica lly downward from a bottom of theservice station and be connected to a sewer pi pe, and the other end of the sewage pipe is connected toa water tray. The water tray extends outward from the front side of the service station. The robot floor washing machine is provided with a walking body, a sewage tank disposed on the body and providedwith a sewage outlet, and a clear water tank disposed on the body and provided with a water inlet. Thesewage outlet is provided with a plug for opening and closing the sewage outlet. The body is providedwith a drainage interface fluidly connected to the sewage outlet. The service station and/or the robot floorwashing machine are provided with a valve driving mechanism for ope ning and closing the plug. Whenthe robot floor washing machine is docked at the service station, the drainage interface is connected tothe water tray, and the sewage outlet is opened, such that the sewage in the sewage tank can flow out to the water tray and to the sewer pipe. Simultaneously, the water faucet can be extended into the waterinlet to replenish the clear water tank with the clear w ater.
