If you have breathing difficulties,
<span style="font-family: 'trebuchet ms', geneva;">I would avoid bagless vacuum cleaners like the bubonic plague if I were you! You can talk about "hygienic bin emptying" features to me until you're cobalt in the face, but at the end of the day you still have to deal with crap flying out of the bin and back into the atmosphere. At least with a bagged machine, everything stays inside the bag -- and some bags even seal themselves up when you remove them from the machine.</span>
<span style="font-family: 'trebuchet ms', geneva;">(Please don't get me wrong -- I'm not bashing anything here. I love some of the bagless machines, and have a few myself. I just don't think they'd be the best solution to this particular problem.)</span>
<span style="font-family: 'trebuchet ms', geneva;">Anyway, I concur with what Matt (PoconoVacMan) and many others have said: look into a Miele or a Sebo. Also, since you're in Europe you may have access to Bosch. They have some really good machines like the GL-30 cylinder (model BSGL3180GB/03) - although that model probably isn't available any more 'cause of the new EU power restrictions (it's got a 1600W motor). Nonetheless, a Bosch would also be a good choice.</span>

it means less dust gets past the shroud and less build up of debris
