Why can't the Xiaomi Robot Vacuum S40 Pro be powered off while on the charging dock?

If the Xiaomi Robot Vacuum S40 Pro can't be powered off while on the charging dock, please refer to the following information:
  1. When the robot vacuum is on the charging dock, it will remain in either charging or fully charged state.
  2. To power off the device, remove it from the charging dock, then press and hold the power button for 3 seconds to shut it down.
  3. While docked, the robot vacuum will automatically enter a low-power standby mode to save energy. This is normal behavior and does not affect performance.
  4. Avoid repeatedly removing and powering off the robot vacuum unnecessarily, as frequent shutdowns can slightly affect battery life over time.
Note:
  1. Never attempt to forcibly disconnect the robot vacuum from the dock to power it off.
  2. Always ensure the robot vacuum is placed on a flat surface when powering off manually.
