Abstract
News editors obtained the following quote from the background information suppli ed by the inventors: “BACKGROUND INFORMATION “Autonomous surface treatment apparatuses are configured to traverse a surface ( e.g., a floor) while removing debris from the surface with little to no human in volvement. For example, a robotic vacuum may include a controller, a plurality o f driven wheels, a suction motor, a brush roll, and a dust cup for storing debri s. The controller causes the robotic vacuum cleaner to travel according to one o r more patterns (e.g., a random bounce pattern, a spot pattern, a wall/obstacle following pattern, and/or the like). While traveling pursuant to one or more pat terns, the robotic vacuum cleaner collects debris in the dust cup. As the dust c up gathers debris, the performance of the robotic vacuum cleaner may be degraded . As such, the dust cup may need to be emptied at regular intervals to maintain consistent cleaning performance.”
