Why can't the Xiaomi Robot Vacuum detect water pools?

The Xiaomi Robot Vacuum cannot detect water pools because its infrared sensors are designed for solid floor surfaces and cannot accurately recognize transparent or reflective liquids. The reflective surface and motion of water interfere with infrared signals, causing the robot vacuum to misjudge the area as a flat surface. As a result, it accidentally entered a water pool during operation.
According to the user manual, the Xiaomi Robot Vacuum is intended for indoor floor cleaning only. It should not be used outdoors, in wet areas, or in commercial environments. To prevent accidents, mark the pool area as a no-go zone in the Xiaomi Home App before cleaning.
Friendly tips:
Avoid operating the robot vacuum in environments such as:
1. Areas near floor-to-ceiling windows, mirrors, or water pools.
2. Dark or reflective floors, carpets, or baseboards.
3. Outdoor or uneven surfaces.
Using the robot vacuum in proper environments helps maintain optimal performance and prevents damage to internal components.
