The child lock feature on the Xiaomi Robot Vacuum X20 Max is designed to prevent unintended changes to the settings and controls of the vacuum, ensuring safety, especially in households with children.
There are two methods to set the child lock function:
1. Press and hold the recharging button on the robot vacuum for three seconds to enable/disable this function;
2. Go to Mi Home/Xiaomi Home APP >> select [Device card] >> tap [Settings] at the upper right corner of the interface >> [More functions] >> [Child lock].
When the robot vacuum is stationary, lock the button to prevent accidental startup. When the robot vacuum is working, it can be started by pressing any button.
