Help Mijia 1c said to clean obstacle sensor.... But..


Jun 20, 2021
Hi guys I was using the 1c robot vacuum for about 5 months, it's a global version. Never had any problems before today.

Today, all of a sudden, the robot decides to ask me to 'wipe the sensors', but the problem is, the sensor was clean, I often clean them once a week.
And its won't move or clean, the power button light changed to red in colour.

Anyone can please give me a helping hand, or some ideas on what is the issue n how to solve?

Cheers, Jin
