According to news reporting originating from Washington, D.C., by NewsRx journalists, a patent application by the inventor Neumann, Rogelio Manfred (Somerville, MA, US), filed on August 2, 2022, was made available online on February 8, 2024. No assignee for this patent application has been made. Reporters obtained the following quote from the background information supplied by the inventors: “Mobile robots include mobile cleaning robots that can perform cleaning tasks within an environment, such as a home. A mobile cleaning robot can navigate across a floor surface and avoid obstacles while spraying fluid or applying fluid via a pad. The fluid can then be absorbed by a pad to effectively perform mopping operations within the environment as the robot traverses the environment.” In addition to obtaining background information on this patent application, NewsRx editors also obtained the inventor’s summary information for this patent application: “Mobile cleaning robots can autonomously navigate through environments to perform cleaning operations, often traversing over, and navigating around, obstacles. Mobile cleaning robots include suspension systems to provide sufficient wheel downforce to overcome obstacles and to provide effective cleaning on various surfaces. Because obstacles can vary in shape and size and because floor types can also vary, a required wheel downforce can vary during operation of the robot. Many robots include suspension systems using an extension or compression spring directly connected to wheel arms, which can effectively deliver downforce; however, in mopping robots, the mass or weight of the robot can vary throughout a mission, altering the preferred delivered downforce for optimal cleaning performance.
