Miele c3 non-powerline version w/ a wessel werk 285 head
I have some miele, not sure if the same model as you. And the best thing about it is that it has 12m cable. Way longer than my previous philips, I just plug it into wall in kitchen a vacuum whole floor in all rooms. Same with second level. So much nicer than having to move to a different wall socket 3 times per floor.
S8s are super, super easy to repair. What broke? The C3 is still available in some stores, even from Miele directly. I tried many other vacs and couldn’t find one that had the power and comfort and the S8/C3. The Guard L1 models are slightly less powerful, but still very good vacs.
Alternatively, the Sebo E3 is probably the closest thing. It doesn’t have as much power, and it isn’t available with HEPA-13 (or HEPA at all), nor is it as comfortable to use but they are very durable and well-engineered. People that don’t like them tend to not like them because of the hose, which is also a common complaint with the D4. Overall, the C3 is significantly more comfortable to use, more power, superior filtration, more aggressive carpet performance, more suitable for residential applications. If it is the motor in your S8 that died, the motors can be replaced in 2 - 5 mins. Very easy, not expensive. $130!USD is what I see that listed at.
The Dyson V8s have awful suction. I suppose they’re okay for hard floor quick pickups but for a mains vacuum, you need a corded canister with a premium hard floor tool. I think Sebo is one of the few companies in the EU that produce power nozzle equipped canister/cylinder vacs. If you can get a Miele canister with the SEB228 power nozzle, and the premium parquet twister hard floor tool, that’s my favorite setup. I used to be an upright vac guy but I’ve been converted. It really isn’t good. They’re also a lot cheaper in the EU than they are in the U.S., but even at US pricing, I find them worth it.
I've owned/ own both and prefer the Miele **C3** for a few reasons. It has more airflow, more suction, superior filtration (H13+) available, an aggressive beater bar (Sebo's is too gentle imo), and I find it significantly easier to use. It's also a very serviceable vac, very simple to take apart for tune-ups, repair, deep-cleaning, etc. I found the Miele C3 to be a lot easier to disassemble than my E3 and D4. I can do it in 2 minutes flat with a drill.
I love the C3 models. They’re hard to beat. I wish more vacs were like them. It wish there was an upright version. Hopefully Miele will make one, at some point.

It’s also important to differentiate between types of HEPA. Miele’s HEPA is H13+ and almost H14. It’s very rare to find H13 in vacuum’s, as most are H11 if they even have HEPA. Rainbows also utilize H13, but aren’t the easiest bags to use if used frequently. I would definitely get a Miele Complete C3, Complete C3, Guard M1 or L1 AllFloors, one with the Parquet Twister floor-head. It significantly better than the AllTeq and FiberTeq heads, and you can get an extra-wide version of it. For rug(s), the TurboTeQ head is sufficient for low pile area rugs.
Miele Complete C3 canister, or a Sebo canister. Both are extremely well engineered. Sebo wands are more durable, but the Miele overlap has the most power, best filtration, and are known for lasting for 10 - 20 years (depending on use rate). It’s also a lot easier to use overall, lots of little things that add up. Sebo’s are commercial grade, more utilitarian, simpler, designed to be used for extended periods every day and still hold up for many, many years; but they come with some traded off drawbacks. I think the Miele canisters are the best choice for residential level cleaning (maybe twice per week for 20-30 mins each time), while the Sebo models are better for commercial level use - using it every day for 45 mins - 1+ hr). Canisters tend to be better for use floors, but both Sebo and Miele sell canisters that are exceptionally effective on carpet - rivaling premium uprights. Get the upgraded hardfloor tool with either brand you go with Sebo Premium Parquet or the Miele Parquet Twister floor head. The Miele version is a lot easier to whip around, but both are premium.
The lightest-weight upright vacs don’t do the best job, but canisters can be exceptionally effective and are the traditional choice for those that want an easy-to-push vac, have back problems, etc. They’re very handy. I used to hate using them but now they’re my preferred vac. They get under furniture, much easier to use attachments with, clean car out with, and they’re a lot better on hard floors. Miele and Sebo are the best canisters. Out of those, I recommend Miele for residential applications - specific models, though. C3 mainly, Guard L1 Electro. Either with the Parquet Twister floor head. The C3 is the best Miele, and has recently been discontinued so get one while you can. Sebo canisters are more utilitarian, simpler, slightly lower performance, but the wands are a little more durable. Still, I choose the Miele for its higher power, comfort features, and excellent filtration.
It was a Miele C3. I can vacuum my house the fastest with it than I can with any of my uprights or stick vacs. Ironic.
A bagged sealed system Miele HEPA is H13+ is the best filtering vacuum available. Ordinary vacuums use H10 or H11 HEPA, and are not fully sealed. Many “sealed system” vacuums are not actually sealed or don’t maintain their seals for long. It is exactly why I bought my C3. The Guard models are even more efficient than the C3, more like H13+.
Miele C3 or Sebo E3 are true sealed, bagged HEPA units. They're excellent for allergies, pet hair, mixed flooring and rugs.
C3 is the best (and probably the one you have). Can fully recommend.
Miele C3 with HEPA filter (corded and with bag). It's really the best you can get. Has a very useful set of tools onboard as well.
My miele c3 has ended up being my most favorite machine ever! The only real issue is finding the best model for your needs. If its low pile or berber the new guard L1 all floor can handle it with straight suction. If its a medium to higher pile the classic c1 cat and dog powerline, c3 kona/marin, or machine with seb 228 will handle carpets really well.
There's not a lot that differs between models. Since you have a lot of carpet the main feature you want is an electric power nozzle. Wheather its a c1, c3, or guard model that's the main feature. When comparing models, filter by the models that come with Seb 228 or seb 236 as they are best for carpets and are height adjustable. The c1 and c3 have cat and dog powerline models, several c3 models, and the new guard L1 electro and some s1 models. All will have a 1200 watt motor. I think most of the cat and dog ones and the new guard ones come with a HEPA filter and all will also come with a suction only head that works well on bare floors and low rugs. Edit, I think the classic c1 cat and dog would meet the requirements. You can buy them online, but if theres a local vacuum store you'd probably get better warranty or more options and accessories!
They all have the same motor, the difference is mainly in the heads/attachments. If you have wall to wall carpets that are medium to high pile seb 228 and seb 236 will do really well. If you have mostly hard floors then pure suction machines can work. There newest pure suction, guard L1 all floor has a new head that can work on low pile carpets from what ive seen, but in my opinion itll be harder to push on the max setting when on carpet. If you can find a good deal on a c1/c3 you can save a little since the new generation is m1/s1/L1.

Miele and sebo are both great and pretty similar, with differences in the power nozzles. Miele is not as user serviceable whereas the sebos et-1 brush is removable. The electric hoses can be a point of failure and the sebo if i remember right has replaceable components on the outside where as Mieles i believe have to replace the whole hose. As for bagged vs bagless, bagless machines are a little more work for the user as you need to maintain the filters and occasionally clean out the canister but are sometimes more convenient. Bagged machines are better if you have bad dust allergies and are generally lighter, because dust is bagged, filtration tends to be better and the canister is kept clean. You still have filters to change, but miele includes the basic ones with their bags which in my opinion are good for the average user. I personally got a miele at a really good price and have really enjoyed it so far. Since you have a lot of hardwood and low pile rugs, you could go for most miele models, theres the guard series, L1, etc. A model with the parquet XL head (16 in) will give a pretty big cleaning path for hard floors!
Its not a bad machine, the plastics can be delicate. The miele and sebo are both good long term machines. I like miele but for carpets you need a power nozzle.
