The german magazin "Stiftung Warentest" (a _very_ respected organization) did some extensive vacuum testing a few weeks ago.

You can see the ranking here (unfortunately in German):

The tested Dyson made last place (from 12 contestants) with mostly average results. It's the most expensive and least effective machine they tested. The biggest disadvantage is the sound level: it was so noisy that it was downgraded.

It got the best note, not the last one. Unless the best possible note is 0... At least that's what I understand from the pages you're pointing to.

The grading system in Germany is quite complicated. We have one were 1 = "very good" (this is the classic system of Schulnoten which is used quite often) and one were 0 = "the worst". For more details have a look at Wikipedia:

And at the end of Highschool (Gymnasium) you have one that goes from 00 to 15. 15 being the best. It is strange.

No, it lost. Germans generally rate things with 1 being the best score, and higher numbers being worse.

Six (or very long ago five) is usually the worst number.
