Yes, I still have a replacement shaver with the 92S shaving head cartridge in use and this can be exchanged with the 94M. According to the manufacturer (see website), the 94M shaving head cartridge is compatible with all models in the 9 and 9 Pro series. In contrast to the 92 combi-pack, which was available in chrome (S), black (B) and matt grey (M), the new model only comes in one colour...

Should work as far as I know....

I would say yes it works

I think so, it is suitable for all series 9 razors 🤔
