Twelve Level 4 autonomous street-sweeping vehicles were deployed in March in Shenyang, northeast China's Liaoning Province.

These electric, driverless vehicles use LiDAR, high-definition vision and millimeter-wave radar for 360-degree perception without blind spots. They autonomously plan routes, avoiding pedestrians and obstacles.

Equipped with sweeping, high-pressure washing and dust suppression, they efficiently clean along edges and dispose of waste.
