This is a video of a white autonomous street sweeper with red and brown accents, operating on an asphalt surface at dusk. The robot is equipped with rotating brushes underneath and features orange lights on the front and top, along with a disc-shaped sensor on its roof. The background shows a park-like setting with trees, green grass, and streetlights, suggesting a suburban or urban environment in Jiangjin, China. Two red banners with Chinese text are visible on a lamppost to the left of the robot. The overall mood is calm and functional, as the robot diligently performs its cleaning duties in the fading light. The Chinese text on the robot reads "新大正" (Xīn Dà Zhèng).
