Was getting multiple positioning failure alerts from the roborock s6 vacuum this evening after cleaning my family room where my 3 and 1 year old were playing. No matter how many times I had the robot dock with the home button, room cleaning was not working and positioning failure would occur. Turned over the robot and opened the brush compartment. A large unbended paper clip was inside interfering with the roller brush. As soon as I removed this everything was back to normal.
Hi, there's an chance the robot may report positioning error when the wheel is not moving freely, which can also be caused by the paper clip in the roller brush.
