I'm pretty sure it's this Einhell Wet/Dry Vacuum Cleaner: https://www.einhell.nl/en/p/2342370-tc-vc-1812-s/ this guy in England seemed quite happy with his: https://www.youtube.com/watch?v=lyOu6TyEUuY

I also wondered about the power extension reels, looks like two of them are the REV model shown here: https://www.amazon.de/dp/B07KKQMVLW although one is a bit battered and the outer blue plate has fallen off.
