black, circular robot vacuum cleaner operating on a dark wood floor. At the start, the vacuum is shown partially under a piece of furniture with black legs, the light illuminating the floor beneath. It bumps into the leg of the furniture and moves away. The camera follows it as it travels across the floor. A person wearing white sneakers and shorts then appears, standing next to the vacuum. The lighting in the room is dim.
