To solve the issue, please refer to the following details:
1. Check whether the robot vacuum is turned off. If it is turned off, press and hold the robot's power button to turn it on;
2. The switch of the robot vacuum's online and offline status is related to the strength of the network signal at its location. If the network signal at the robot vacuum's location is weak or unstable, it will be offline. Being offline during normal operation will not affect its continued cleaning. When the network signal is better, it will automatically return to the online status;
3. You can add or reset the network for the robot vacuum, and select a router close to it to configure the network;
4. Check whether your home Wi-Fi is working properly.
