China-made autonomous sweepers are grabbing attention all over the globe, as the country uses its technological expertise (专长) (release) new quality productive forces in the field of cleanliness.
A Shanghai-based high-tech company has received world's first road testing license for autonomous sweepers. The company's latest product, (launch) in March, combines three cleanliness tasks—sweeping, road spraying, and garbage transportation and is able to cut overall cleanliness operation costs by 70 percent. Equipped technologies including millimeter-wave radars (雷达), cameras and high-precision positioning, the sweepers can achieve precise edge fitting, safe obstacle (障碍) avoidance, emergency avoidance, flexible turning and direction switching during operation.

The vehicles operate powerfully, especially during extreme weather. After completing the daily cleaning tasks, they (automatic) drive to the garbage collection area and complete dumping (倾倒) task by (they).
Liang Haiming, director of Hainan University's Belt and Road Research Institute, said that unmanned sweepers made in China have advantages in automation technology, smart management and the application of new energy, helps to improve safety and work (efficient).
"In addition to cleanliness, the field of autonomous driving (include) limited and low-speed environments such as distribution, shared travel, public transportation, ports and terminals, and mining operations," Liang said.
