Question for people living outside Finland:
See the picture in link. This is a public place to wash your mats/rugs/carpets.
Do you have such places in your country? If yes, tell your country in comments.

@grumpysmiffy a bit like that, yes! Knuffel can also mean a plush toy, and that was more like what I had in mind, but best things are always ambiguous. :)
