I paid $1,100 for my Bosch 500 series dishwasher a couple years ago. The current generation looks like it's on sale for as low as $800. Yale Appliance shows Miele dishwashers currently starting at $1,400. With that kind of premium it should feel better. And, yes, the Bosch feels super cheap.
Miele washing machines start at $1,600 about twice what an entry level LG would cost. While I would never buy an LG, they are generally well regarded in terms of actual washing performance.
The Miele laundry machine was 700€ back in the days and the fridge 1400€.
So, it is not that much more expensive here in Germany.
Sure, for a few thousand dollars more I could get a dual compressor Bosch. Or I could spend the money on pretty much anything else. Miele is sold as a luxury brand out here and while luxury white goods are nice they command a hefty premium.
I like my Miele old school stick vac, but it was made in China just like everything else these days… and I wince every time I have to buy bags and filters for it.
