That germ killing thing was I think mostly present in the Karcher's TSC555. My mum used to work at Karcher in the late 90s and they were still available in Poland, I remember seeing it in one of the catalogs describing its magical powers. Ibaisaic has a really cool video on it and in the end you can see him using the germ killing function.
