I purchased a robot vacuum cleaner in 2019 and have been using it well.

After about 5 years of use, suddenly the cleaner stopped working!

It made noises as if trying to work, but wouldn't move, and displayed a message saying "LDS sensor error." Upon investigation, it turns out the rubber belt in the sensor area had worn out due to prolonged use...

I successfully disassembled it easily after loosening just a few screws to remove the cover, and while at it, I cleaned it since it was quite dirty due to long-term use...

Originally, there was a black rubber belt, but as soon as I opened it, I found it was broken, so I replaced it with a yellow rubber belt that I found lying around the house.

After reassembling it and testing, it operates normally again... For now, the yellow rubber belt is just a temporary fix, so I'll have to get a proper rubber belt soon and repair it properly...

Let's use it for a long time... Robot vacuum cleaners are expensive, after all ^^;
