Questions about Braun Series 9

You write above that this unit has a 3 year warranty from the factory, and the warranty does not say 2 years - what is correct now? Sincerely (The 9292cc version already has a three-year warranty from the factory. The device also has the Responsive Intelligenc function which ensures that it can adapt better to the contours of the face).

Hello I have the Braun 9 series 9291cc at my work address I wanted to know if the shaving heads are identical between the 9292cc and 9291cc?

Good day Can the Series 9 also be cleaned and charged in the Series 7 cleaning station? Thank you for your help!

The manufacturer's warranty is stated as 3 years, and the warranty can also be extended to 3 years (?) for an additional charge of approx. 25CHF. I don't quite understand the meaning behind this. Is this extension necessary at all or is the manufacturer's warranty incorrectly stated? Thanks for your help :)

Dear Community, I can't find the difference to the 9290cc (link below)! Except that the 9292cc is newer and almost twice as expensive, I don't see any difference?

Does the shaver have to be cleaned in the station or can it also be cleaned dry with a brush - as I have been doing for years. I do this every day.
