Why does the Xiaomi Robot Vacuum 5 Pro report water shortage even though there is water in the water tank?

The Xiaomi Robot Vacuum 5 Pro can report water shortage even when there is water in the tank. This is part of its design to ensure smooth cleaning performance and prevent unexpected interruptions.
To help you understand better, here are the possible reasons:
  1. When the clean water tank has around 500 ml of water or less, the system reports a shortage. This early reminder is intended to prompt adding water in time, preventing the water tank from running completely dry and ensuring the next cleaning cycle is not affected.
  2. If the clean water tank is filled but still shows a shortage, check whether the float inside the tank is stuck, not floating properly, or has fallen off. A misaligned float can cause the system to misread the water level.
