What it means
In the Roborock S6 troubleshooting table, Error 2 means the bumper is stuck. The robot uses the bumper to detect collisions and, if it stays pressed in, reads a constant bump and stops. The manual says to clean it and tap it lightly to remove any blockage and, if there is none, to move the robot to a new location and restart it. The code does not prove a faulty mechanism; only if it persists after those steps do you need to email after-sales service.
