This guide explains the "Mower locked" or E9 error on your Landroid device. Once the function has been enabled, it triggers when Landroid isnât able to communicate with the Wi-Fi network for 72 hours: the robot will get locked and wonât work anymore.
If your Landroid gets accidentally locked (e.g. you experience a power outage, the router goes offline, etc.), youâll just have to bring the Wi-Fi back online and make sure the robot is connected to it.
Please follow these steps to unlock the mower.
First make sure that your Wi-Fi network is online.
Then put your robot back within Wi-Fi range, and double check that it is connected to the network.
After 10/15 minutes, the robot should be unlocked and it should resume operations according to the schedule.
