The mobile application for this Mi Robot has a number of serious software flaws. The connection between the robot and the smartphone remains severed at all times. There is one successful connection out of every 15 attempts. At night, his indicator frequently lights red, which he finds annoying because it obscures the view. After reading so many glowing testimonials, I can't help but wonder whether or not my software has been upgraded (but this is inaccurate). Nevertheless, if you check the evaluations that other people have left about the app in the Play Market, you'll see that I'm not the only person who had such terrible luck. My review will most likely not be published because to the fact that iRobot does not permit negative reviews to be written about their products. There have been no complaints made about the robot itself; it does its cleaning duties effectively, especially after being prompted by nearby tambourine-playing dancers.
