The drawback with the Miele S2 is that its the bottom of the Miele Range and sells in the UK without the PN for between £99 and £140 - so the price of $699 is very high just for a power nozzle, when you could get one with an air driven turbo brush for less. Do you really NEED an electric head for use in a static caravan? Electric heads (Power nozzles) make the hose heavier and more unwieldy, also with the reliability factor of internal wiring breaking over time. The air driven heads are very good on shorter pile carpet or for smaller carpeted areas. They also don't need an electric hose. Also on the Miele S2, the small accessory tools that come as standard with any Miele don't store inside the lid of the cleaner, but have a clip on plastic caddy that seems an afterthought. I have the Miele S6, which also stores its small tools outside the vac, its a smaller body but a smaller dustbag at 3.5Litres. I also have an S8, which is the model I'd recommend for larger homes, with a turbine head - its tools store in the machine, and it has the 4.5 litre Hyclean dustbags the same as the S2. It also has electronic power control. No Mieles use the handle operated electric motor suction controls now except the S8 Uniq.

For your smaller space - I'd say an S6 Onyx would be more compact - and if you have short pile carpets then the air driven turbo head would work out better value - see the link for details ($499). I have the equivalent model in the UK and its a great cleaner, small and compact, and the turbo brush is great on cut pile carpet, and this is the model I'd recommend. Unless you have severe allergies the basic Airclean exhaust filter is all you need, as all bagged vacs start to smell in the end, especially if you have Dogs. You get a new Airclean exhaust filter with each box of Miele genuine bags. Even the charcoal and HEPA filters don't completely stop the smell, and they have to be bought in addition to bags, and are a once a year expense as you have to keep replacing them.

The S6 without the PN is also very easy to store and has a small footprint, as my model S6 shows here:

Or it can compact even smaller with the wand removed (Turbo head shown)

The question has to be asked - If Daknx94 lives in a Mobile Home, does he really need an expensive power nozzle setup? Its not as if he is gonna have wall to wall shag that really needs a PN - is it?

In the UK, most of us now use air driven turbo nozzles, and these suffice very well. It all depends on pile length and the amount of carpeting that has to be cleaned, and in a Mobile Home, there's not gonna be that much area to cover, plus it will save a lot of money by not  going for a PN option. The only reason he might need a PN model is if all the Mobile Home has shag carpeting and he has pets, where ingrained dirt and fur is a problem.

MObile home with a need for a PN?:

That's what we call a Static Caravan.

This is what I call a Mobile Home / Motorhome:
