So off to the dealer, diverse devices considered and tried it out briefly, and quickly turned out:
This Miele vacuum cleaner is simply the HAMMÄÄ!
2000W speak for proper suction power, but the 2000W position you almost never need because thanks to optimum air circulation the suction power is impressive even on the second smallest (!) Stage. In the next stage he already sucked up the carpet tiles, and then there are other three stages.
He is even at full power still quite low, the engine can be heard even then only a subtle buzz, and to the weaker levels the Motorgeäusch goes back so far that you only hear hiss the nozzle. It is sufficient, as already mentioned, the suction power even then for the most comfortable out.
In the shop I could tango with another Miele (series S6 with 1200W motor), a very compact and strong, but HELL loud AEG and Siemens compare, the latter was supposed to bring much slack 900W suction power as other devices with 2000W.
It quickly became apparent that Siemens was outclassed downright from the current to not even half speed tango, and the 1200W Miele S6 made sense to use only at the highest level.
Add to that the integrated accessory compartment of the Tango, which offer neither the "modern" S6 (OK, at least offers an external nozzle holder) nor the Siemens (in which there's garnix, so nozzles getting extra lug).
As an alternative to tango there were still the in-house "successor" from the S8 series, but except for a slightly rounder case and a minimally more powerful engine, but felt despite 200W more at the nozzle is not brought just phenomenal suction power of the tango, had nothing to offer, but more than 80 euros would have been more expensive.
Thus, the decision was clear. A small improvement was made on the advice of the dealer on the spot: thanks to the modular design you can easily replace the standard exhaust flat filter for a filter cassette (SF-AH30 HEPA or SF-AAC30 with activated carbon filter), which again brings something improved exhaust filtration, but the standard is already OK.
And if it sometimes a problem is (see below), the very service-friendly design facilitates a possible (and even executed) Repair enormous!
Only a couple of Torx screws (standard size, not as a "security" -Pseudotorx spasm) solved, and you can remove the lid without any plastic clamping-Zerr lock up and has all components easily accessible in front of him. If everything is well solved plugged, still partially secured with screws.
My Tango had in fact during the initial commissioning a small problem: Because "something" much lubricant was used in the field of Kabelaufrollers arg, had the "brake" of the (otherwise incidentally very thoughtful act, not a simple "cable clamp brake", but just a brake directly to the winding spindle) retractor lack of grip, the cable popped always equal pure again.
Device as described open ruckzuck, wiped the excess fat, friction surfaces worn by "Brake" and "pad" with alcohol, cover back on it and good.
All together bring less than 5 minutes incl. Torxbox from the basement and leave to dry Spiri because I know vacuum cleaners, where you comfortable spending time alone with the triple opening the case.
Considering that soon, may be pronounced no longer made from the beginning of 2014, Hoover this performance class "thanks to" a new regulatory harassment of Eurocrats or sold as a new device (exception: special offers), I can only to the part a very clear
Give buy rating.
More suction power with top processing (which can happen with the fat even once and was quickly resolved) you do not get in this price range well!
