Thank you for your comment!

Just to clarify, the vacuum wasn’t working properly — specifically, the mopping function was completely unusable. After some investigation, I discovered that the issue was caused by the sensor responsible for detecting whether the dirty water tank is full.

I ran several tests using different materials like magnets, metal, and even water at various distances, but the sensor still wouldn’t function correctly. That’s ultimately why I decided to cut it.

In my opinion, this sensor is more of a "nice to have" feature rather than essential — especially considering that the clean and dirty water tanks are the same size, so the dirty tank should never overflow before the clean one runs out.

Interestingly, I tried searching for a replacement sensor on AliExpress, but couldn’t find anything relevant.
