Just purchased and it cannot go into the home for charging

L40 s ultra.

Some bases don't like carpets.

Hi,

Please follow the steps below to troubleshoot：

1. **Check the base station adapter plug**:
- Please check if the base station adapter plug is loose and if the base station is properly powered. Check if the rocker switch on the back of the base station is in the ON position and ensure that the base station indicator lights are on.

2. **Test the recharge function**:
- Please place the robot 1-2 meters in front of the charging station, then short-press the recharge button to observe whether it can be recharged successfully.
- If it can be recharged successfully, please confirm the following:
- The charging station needs to be placed against the wall. It is recommended to leave 0.5 meters on each side and no obstacles in the 1.5 meters in front.
- Please make sure that the charging station is away from signal interference devices, such as routers, TVs, etc.
- Make sure there are no mirror reflectors (such as mirrors, windows, etc.) on the opposite side to avoid affecting the navigation of the machine.

3. **Confirm that the laser sensor is working properly**:
- Please confirm whether the LDS laser sensor on the top rotates and works normally when the robot starts working from the charging station. Observe whether the sensor has any abnormal sound or behavior.

4. **Check the driving wheel**:
- During the robot's operation and return to the base station, please check whether the driving wheel is slipping, stuck or trapped. If this is the case, please wipe and clean the driving wheel to ensure that it is operating normally.

5. **Restart the robot**:
- If the above checks are all ruled out, it is recommended that the user try to restart the machine and clean again.

6. **Precautions for changing the base station position**:
- When  changes the base station placement, make sure the robot is placed on the new base station and start the cleaning test from the base station.

7. **Reset**:
- If the problem still exists after restarting, try to reset the robot host. After resetting, move the charging station to an open area and try cleaning again.

8. **Arrange after-sales repair**:
- If the problem is still not solved after the above checks, please contact support.na@dreame.tech
