Why does the Xiaomi Robot Vacuum collide?

Question

Accepted Answer

Xiaomi Robot Vacuums can effectively navigate around most obstacles. In rare cases, minor contact can occur due to factors like dirty sensors, unusual lighting, or complex room layouts.
For your reference, please follow the steps to troubleshoot:
1. Wipe the obstacle avoidance sensor lenses on the front of the robot vacuum with a soft, dry cloth to remove dust, fingerprints, or residue that blocks detection.
2. Dark, highly reflective (metal) surfaces, transparent objects (glass walls), small furniture legs, low obstacles, or objects in blind spots occasionally go undetected, resulting in minor collisions.
3. Detection of certain objects—such as fabrics, power cords, pet waste, shoes, charging dock, or scales—can be reduced in dimly lit environments.
4. When approaching soft objects like curtains or slightly open doors, the robot vacuum slows down and gently bumps into them, which is a normal behavior.
5. In homes with many obstacles, the robot vacuum collides while attempting to navigate around or escape from tight spaces.
6. If obstacle avoidance sensors are damaged or malfunction, collisions occur even with obvious obstacles.
Regular sensor maintenance, proper lighting, and a clear cleaning environment can help minimize collisions and maintain safe and efficient navigation.
