Actually it is really simple. Vertex sells different sized lids to fit any skimmer so it is kind of universal. Problem is I can’t find vertex products anywhere in Europe right now. It seems De Jong in the Netherlands carries the brand but I can’t find the products anywhere.
Alternatively you can buy the AquaDriver SkimCkean. It is the best one out there. German engineering and precision.
With my vertex cleaner I only clean the cup once every month or more. Ivinltly have to empty the cup every week. Very convenient.
But given the bottle shaped body of the Nyos not sure how well it would work...
