Fortunately, you can reflash the robot vacuum cleaner into Russian yourself without going to the service center. In this article, we will discuss the process in detail through the Android smartphone, which will become your main tool. The method is suitable for most models of Xiaomi Mi Robot Vacuum, Dreame, Viomi and other brands of the ecosystem. Importantly, the procedure requires care, but if done correctly, does not pose risks to the device.
