Why does the Xiaomi Robot Vacuum S40 Pro bump into the wall during edge cleaning?

If the Xiaomi Robot Vacuum S40 Pro bumps into the wall during edge cleaning, please refer to the following information:
  1. The device uses a mechanical bumper and wall-detection sensors. During edge cleaning, it can bump lightly into baseboards or dark-colored walls to maintain the correct distance.
  2. Such contact is part of its obstacle avoidance and edge-following logic and is considered normal behavior.
  3. The robot vacuum adjusts its path after detecting the obstacle, which allows the side brush to sweep up dust along edges more effectively.
  4. If collisions seem stronger than expected, check whether the sensors and bumper are clean and unobstructed.
  5. Keep walls and baseboards clear of hanging objects, cords, or fragile decorations to avoid potential damage.
