If not, then the only option is to buy it in Germany for EUR 1,599, reclaim the VAT and pay the correct tax. Then, at the current exchange rate, you are at around CHF 1,420. Please note that the inlet pressure must be between 1 and 4 bar and the outlet must not be higher than 50 cm above the floor (see manufacturer's website). I would buy this as it is annoying to refill / empty the water tanks every 3 days in a small flat. (I already have the S8 Ultra...)
