News editors obtained the following quote from the background information suppli ed by the inventors:“An autonomous cleaning robot can navigate across a floor s urface and avoid obstacles while vacuumingthe floor surface to ingest debris fr om the floor surface. The cleaning robot can include rollers to pickup the debr is from the floor surface. As the cleaning robot moves across the floor surface, the robot canrotate the rollers, which guide the debris toward a vacuum airflo w generated by the cleaning robot. Inthis regard, the rollers and the vacuum ai rflow can cooperate to allow the robot to ingest debris. Duringits rotation, th e roller can engage debris that includes hair and other filaments. The filament debris canbecome wrapped around the rollers.”
