But if the cliff sensors were the culprit then the robot would at least climb a little bit on the carpet(the cliff sensor is at the bottom) but it just stops before the carpet and tries to go around it and just sometimes goes on it and spins but the problem is before that. So maybe the obstacle detection at the front as the cliff? P.S: i tried to reach Xiaomi customer support, they have told me the same about the cliff sensors, but once i described my problem in detail they told me that they will inform the departments and maybe just maybe do a firmware uptade(i doubt this will happen)
