Question about Xiaomi X20+

The Xiaomi X20+ (Robot Vacuum Cleaner) can clean corners and nooks, but its performance in these areas is not always optimal. It uses an LDS laser navigation system and structured light for obstacle detection, which helps it to navigate efficiently and avoid obstacles. However, a test shows that the robot cannot always pick up all debris in corner areas, such as in a test where it only picked up two out of five corn kernels in a corner.
