Dustbot ® 5409; SO-G ® was the first purpose-built robot to feature a built-in vacuum cleaner. Dustbot's large eyes flash red and his arms move creating a sweeping action for the broom, while his vacuum functions. He really vacuumes, he picks up small pieces of paper, dust, crumbs, etc. He senses any edge and turns away, for he is the robot with a brain, that vacuums.
