Charging during mowing

Hi. My 600 fails to return to charging station when (always) during mowing, the battery is down.
Should it go back to the station at a certain battery level in order to recharge and start back mowing ?
There are no obstacles. Simply the battery is down and it doesn’t start the returning process on time.
Any suggestions?

Hello, the robot will automatically return to the base station when the battery is low. What is the automatic return charge level you have set?

I actually didn’t set it. Could u be so kind to explain me how to set it?

Sorry, this feature was removed in a previous firmware update.

The robot's default return-to-base threshold is 15% battery. It is abnormal for the robot to fail to return to the charging base due to depleted battery. Please follow these steps to check:

Check for obstacles blocking the path between the charging base and the work area.

Ensure the area within 1 meter around the charging base is clear and level

Verify the charging base has not been relocated. Moving the base may also prevent the robot from returning. You can manually guide the MOVA 600 back to the base via remote control; the robot will automatically update the base location during its next operational cycle

Confirm the base is connected to power and functioning normally. Under normal conditions, the indicator light should be solid blue

Is the base station's reflective sticker clean and unobstructed?

Check for nearby reflective objects similar to the sticker, such as mirrors, reflective road signs, open umbrellas, or highly reflective metal railings that may mislead the MOVA 600.

Is the base station's base plate or the robot's drive wheels clogged with dirt?

Is the MOVA 600's radar clean and unobstructed?

If the issue persists, please upload logs via the app and privately message us with the robot's SN number and firmware version.

Thank you very much for the explanation.
I stupidly thought the sticker didn’t have any function and threw them away but now I’m getting the point. Is it any chance  to buy them ? I would really appreciate your help.
Regards.
