I have no idea. You can see which device it could be on the Philips homepage under shavers. (I am not a Philips expert)

No, I haven't found one yet. And Philips support / sales couldn't tell me one either 😔

Compared to the Prestige (XP9202/10), the Prestige Ultra (XP9404/46) offers an even closer shave, more comfort functions and a UV charging case.

The shaver "Philips Shaver Series 9000" on Galaxus (model S9974/35) is not identical to the "Shaver Series i9000 Prestige Ultra (XP9404/46)". The i9000 Prestige Ultra (XP9404/46) is a premium model with SkinIQ Pro technology, 5 individual shaving modes, a UV cleaning device, Quick Clean POD, and a 7-year warranty offer. It features NanoTech Dual Precision blades, 360° precision head and intelligent sensors to adjust shaving performance. The S9974/35 model from the Series 9000 on Galaxus is another Series 9000 model that is usually sold without the extensive accessory set and advanced features of the Prestige Ultra. It is more of a standard Series 9000 model, while the Prestige Ultra is the top-of-the-range version with more technology and accessories. If you're looking for the same shaver without all the kit and bells and whistles, the model on Galaxus is probably a simpler version of the Series 9000, but not exactly the same as the i9000 Prestige Ultra XP9404/46.

Yes, even on Digitec for around CHF 238.
