5 minutes after turning it on, he said that "the collision sensor is stuck." The robot in a human voice advised to knock on it so that the sensor would snap back. Xiaomi, this is just top quality! I remember in the Soviet Union you had to knock on TV to make it work. Xiaomi, are you still in the Soviet Union? When searching on the Internet, I found that this is a problem with the xiaomi sensor. Not tapping, not purging, not rebooting and ating the firmware did not help. The robot drives three meters and asks him to tap. Here is such a robot masochist. Took it back to the store.
