S314 Red Star Power Team

I'd go for either the red Miele or the Felix.

The white one is 25 years old and not suitable for carpeting. The red one is the far better choice.

It’s an S300, they haven’t sold them since about 2005. That model has the entrance cover too, which wasn’t used into the 2000s afaik.

Have a Samsung jet. It is good but you still need a proper vacuum as well. The Samsung I use for quick whizz around and it's great for taking up to our loft bedroom but none of them perform anywhere near as well as a wired vacuum like a Miele S3.  I'd invest more in a proper vacuum then buy a relatively basic cordless one for those quick clean up jobs. 

Miele. Easy to repair, high quality.

We have two Miele cylinder vacuum cleaners, one upstairs one down. The upstairs one was bought new in 1992 and still works faultlessly. The second is a much older design obtained for £0.00 from Freecycle (when that was a thing) about 15 years ago. Both perform powerfully and faultlessly*. The older one has a powered sweeper head which works well on both carpet and hard floors. I got it from a posh lady who said she was embarrassed when friends came around for coffee and saw her “ancient” vacuum cleaner. She had replaced it with a new Miele to save her blushes. Both are 1500W and extremely powerful. *The cable retractor on the upstairs one made a squeaking noise when operated. My first wife told me to fix it so I sprayed it with some WD40. It stopped the squeak but the retraction process has since needed human intervention. 🙄 -oo-

Any Sebo Machine, or any of the Miele machines that have a power brush head would be a good bet. The Dyson machines are not at all bifl, they are cheaply built disposable vacuums, not recommended at all 

Miele S series bagged vacuums are one of the GOAT imo. Ours has lasted years and if you buy generic bags, upkeep is a minimum

holy shit god bless you for this lol this is so inside baseball but so great to have omg. have an organization I’m working with trying to figure out a vacuum situation and they’re so sold on the gm80 (obvi great and what I trained with but $$$$ I think someone else sold them on it… rightfully so but it’s just so pricy) but the cost of the museum/rheostat models is obviously so steep it makes me insane. i get sooo frustrated w/ the state of info on this sort of thing– have genuinely always suspected that there’s a lot of opportunity for DIYing this particular aspect (there’s enough crossover with like, dust extractors&some aspects of cnc routing vac/dust remover things that people have had to diy) but obviously the field is so small & “quiet” that it’s been hard to find resources. for OP- i *have* used variable speed Miele vacs with HEPA filters on the “curtains”/drapery settings on some pretty delicate stuff w/ cheesecloth and muslin to dampen and it’s worked fine. also hear decent things about HEPA filter variable speed dust extractors by Festool– they are very well respected/truly Loved in non museum contexts & i know some conservators that use them!! but haven’t been able to personally try them out yet

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.
