Miele makes darn reliable appliances, I've had two Miele vacuum cleaners from -88 and still both work fine. Used weekly, one at home and when I sold summer cottage to my brother & his wife I gave one to them, they still use it there.

All parts still available and when I bought new hose few years ago from service I asked if they still are willing to fix it if it went broke answer was. Sure absolutely, just bring it here and we make it work again. I've just bought once new floor nozzle that was worn out and that hose because it grew leaky from ends. Third party dust bags are available and very cheap.

Not anymore. I bought a brand-spanking new high-end Electrolux dishwasher and discovered it had a flimsier construction than the 20 year old one my mom has at home, that was an absolute bargain bin purchase.

I expect companies to honour their legislatively required, and their advertised, warranty.

Yes. But. There's many companies that build up a reputation then cash in on that reputation. Eg Mercedes in the 90s. So you could end up paying more for cheap rubbish.

It would be nice if the EU or someone introduced an energy star type system for reliability and repairability so that consumers could have some kind of idea what the quality is likely to be.
