Why does the Xiaomi Robot Vacuum sometimes miss spots in a room?

The Xiaomi Robot Vacuum occasionally leaves certain areas uncleaned. This can be caused by room layout, obstacles, or environmental factors that affect navigation and coverage.
For your reference, please follow the steps to troubleshoot:
1. Check for obstacles near doorways or missed areas. Items such as carpets, mats, wires, or shoes can block the robot vacuum from entering certain spaces. Remove these obstructions and run the cleaning again.
2. Thresholds or step heights greater than 2 cm, very dark floors, direct sunlight, or narrow and elongated areas interfere with the robot vacuum’s sensors, causing it to skip spots.
Ensuring a clear path, minimizing obstacles, and adjusting environmental factors can improve cleaning efficiency and reduce missed areas.
