News editors obtained the following quote from the background information suppli ed by the inventors: “Autonomous cleaning robots are robots which can perform de sired cleaning tasks, such as vacuum cleaning, in unstructured environments with out continuous human guidance. Many kinds of cleaning robots are autonomous to s ome degree and in different ways. For example, an autonomous cleaning robot may be designed to automatically dock with a base station for the purpose of emptyin g its cleaning bin of vacuumed debris.” As a supplement to the background information on this patent, NewsRx corresponde nts also obtained the inventors’ summary information for this patent: “In one as pect of the present disclosure, a robot floor cleaning system features a mobile floor cleaning robot and an evacuation station. The robot includes: a chassis wi th at least one drive wheel operable to propel the robot across a floor surface; a cleaning bin disposed within the robot and arranged to receive debris ingeste d by the robot during cleaning; and a robot vacuum including a motor and a fan c onnected to the motor and configured to generate a flow of air to pull debris in to the cleaning bin from an opening on an underside of the robot. The evacuation station is configured to evacuate debris from the cleaning bin of the robot, an d includes: a housing defining a platform arranged to receive the cleaning robot in a position in which the opening on the underside of the robot aligns with a suction opening defined in the platform; and an evacuation vacuum in fluid commu nication with the suction opening and operable to draw air into the evacuation s tation housing through the suction opening. The floor cleaning robot may further include a one-way air flow valve disposed within the robot and configured to au tomatically close in response to operation of the vacuum of the evacuation stati on. The air flow valve may be disposed in an air passage connecting the robot va cuum to the interior of the cleaning bin.
