The smartphone application for this Mi Robot is terribly buggy. The robot is constantly disconnected from the smartphone. One connection out of 15 is successful. At night, his indicator often glows red, which he doesn’t like, it’s not clear. Seeing so many rave reviews, I make myself think that my robot has moved out the software (but this is inaccurate). Although if you read the reviews about the application in the Play Market, then I'm not the only one who was so unlucky. Of course, my review will not be published, because you can’t write bad reviews about iRobot. There are no complaints about the robot itself, it cleans up well, after dancing with tambourines, next to it, so that it starts this cleaning.
