Abstract: A method for operating a robotic device. Usage data and a first location of the robotic device are determined. A first sensor of the robotic device captures first data indicative of an environmental characteristic of the first location. A first operational parameter of a first actuator is adjusted based on the first data while the robotic device is at the first location. A debris map of the environment is formed based on debris data output by a second sensor configured to sense debris on a floor. A request for cleaning service at a location is received, wherein the robotic device is one of a plurality of robotic devices that provides surface cleaning services to a plurality of users. The robotic device to respond to the request is determined based on location, fill volume of a debris container, battery charge, and availability of each of the plurality of robotic devices.
