Prices in Europe are more reasonable for Miele, Sebo and the Henry. Miele S series, Sebo K series and Henry would be the models I'ld be looking at.

Miele is consistently rated as the best among impartial, professional reviewers & can be bought for $300-$500 depending on the model They last a long time as well. Personally I use a Samsung Bespoke Jet, mostly for the convenience factor of having a dust station & no long cables to deal with. We also have an old Miele S series that does a good job after almost a decade (motor overheats a tad though).

Used Miele S series are also really good value and reliable, plus repairs are super easy too.

If you get a room a for daily upkeep, get the one that empties itself. I love my room a but wish I would’ve gotten the self-emptying base. My upright is a Riccar. I’ve also owned a Miehle canister vac. Both are outstanding

I have  Miehle canister vac that has worked flawlessly for 30 yrs and still going strong. 

I've seen Miehle's for sale on the internet for less than $500. Just looked a few weeks ago.

It's the lift away one, was never very good. Years ago I have a 1200 watt meile thing that got stolen during a break in to a flat I rented.

If you want a decent stick vacuum, I got mine at Costco it’s a green works model. I prefer it to the Dyson for daily use. If I do a deep clean I like my meile canister vacuum.
