Yep, that is issue =(

I have reported that many months ago.

Only trick is put painters masking tape to bottom sensors, but then there is no cliff detection anymore.

Maybe we all send report to xiaomi, so they really understand that this is issue what should be fixed ASAP?

All brands of robots have this problem with dark floors because of the standard type of proximity detectors used, depending on intensity of reflected light beams off the floor. Covering the cliff sensors is the standard treatment.
The detectors work with a lot of visibly black materials, but apparently certain carpets and hard floors are uniquely absorbing in IR light.

I am experimenting with an alternative method using parallax which would require making custom sensor PCB's and still might not work. Will see, but higher costs could be incurred. Will report in the hacking forum.

My Xiaomi gives an error message with wall to wall carpet that the brush is dirty, but I just clear the error and resume the cleaning. Usually, it finishes with no issues. Very little dirt on the brush overall, seems the unit is mostly engineered for hard surfaces so if it picks up too much resistance in the brush, it gives an error. Would probably not recommend the unit for shag wall to wall carpeting (but then again it's not 1980 anymore!)
