Miele is a pretty well known standard german brand no? I'm sure they have higher-end stuff but i dunno, maybe you could have researched it, or just didnt find the need before?

There's a pretty good saying about 10$ boots that last a year or 100$ ones that last 10 years

If you're well enough, you can probably afford more things that you can use anyways, so it makes sense to optimize for those that give you the most kicks for your bucks, even if they're technically more expensive.
