A newly filed patent (Publication Number: US20240033781A1) describes a cleaning station for a mobile robot that includes a fluid vessel, a roller submerged in cleaning fluid, and a control system that rotates the roller to direct the cleaning fluid onto the robot's cleaning pad to release debris. The roller can translate with respect to the robot, and a translation mechanism facilitates this movement. The cleaning station also features a docking surface, a spring-loaded mounting for the roller, and a conduit system for the cleaning fluid to flow back into the vessel after use. Additionally, sensors monitor the contamination level of the fluid, prompting the control system to repeat the cleaning cycle until the contamination level is below a threshold value.

Furthermore, the patent includes claims for a mobile cleaning robot with a drive system, a pad holder for a fabric pad, and a control system that docks the robot at a cleaning station for a pad washing routine. The fabric pad can move with respect to the docking station, either through the robot's maneuvering or a translation mechanism. The system also describes a setup where a cleaning station with a roller interacts with a mobile robot with a fabric pad, allowing relative translation between the pad and the roller during the cleaning process. These innovations aim to enhance the efficiency and effectiveness of cleaning operations performed by mobile robots, ensuring optimal debris removal and maintenance of cleaning equipment.
