I heard a clunking in the vacuum while it was running and found that the lens of one of the side lasers has fallen off. I was able to shake it out but have no clue on how to put it back . The bumper cover doesn't seem easily removable.
The glas can only be replaced by a service station. We have made improvements to that part so that it does not come out as easily. Contact service on the number found in the application. They will be able to direct you to the right place
