A laser collimator should be (perfectly) collimated at the factory. If this is not the case, it is (theoretically) possible to collimate it yourself. However, if this is not possible - as in my case, because I had no way of turning the…
Snap lugs in the tray of the dust compartment on a Vorwerk Kobold VR100 vacuum cleaner robot were broken, so it was not possible to use the cleaner anymore, which was otherwise still working fine. There are no official solutions and it's…
