Don't have any experience but Lindhaus except I have heard of them. I have two mieles and I love them.

Good luck!

I have a Lindhaus. It is an upright, not a canister. It cleans very, very well. I have a couple of issues. The beater brushes are so effective, they will, on a very dirty floor (pet hair) on occasion, get ahead of the suction and the head will plug. I have never had this happen to me, but the kids have managed it a few times. I suspect it is because they are racing around as fast as possible. It takes a while to notice the plug because the brushes keep picking up dirt anyway. The other minor issue is the piece that holds the hose is a little flimsy. I believe the newer models have addressed this (mine is 8 years old).

The bare floor head is the best I've ever used. Both heads that I have clean right up to the edge. The bags are designed very well, as are the various filters. You can even get HEPA filters for many models.

We had a Lindhaus upright.
After 5 years it needed service and all the local vac shops dropped Lindhaus.
The closest dealer is about 100 miles away and I live in Seattle.
couldn't get parts on line.
Calling lindhaus was no help they wouldn't sell direct and the dealer 100 miles away never responded to my email.

I posted before Christmas about looking for a cannister vacuum. My husband did buy me the Lindhaus Aria Elite, and I love it. The bare floor attachment sucks everything up, and the carpet attachment is sturdy, and my carpet looks great. I previously had a Windtunnel 2, and it in no way had the same suction power. I like that you can change the suction power.
I would highly recommend this cannister vacuum, and will probably get an upright Lindhaus for the downstairs, since it is all carpet.
