"When the L11 pro robot vacuum does not respond after you press any button, please press and hold the power button for 10 seconds to turn it off(when it is not recharging), and then press and hold the power button for 3 seconds to turn on.
If the robot does not work properly after resetting, please try to restore the factory settings by pressing and hold both the power button and the recharge button for 8 seconds at the same time until you hear a prompt tone.(when it is not recharging).
The robot will clear all information and settings. At this time, you needs to reconfigure the settings (including the network settings）"
