Bit off topic perhaps, but in my experience: Dyson does not necesarily work great nor handles well nor does last particularly long. Ok this is only anecdotal from my experience and 2 friends (Animal pro models or similar) but still.. Main complaint: it's overengineered/designed to the point it degrades usability. The handle is about twice the weight of a 'standard' one. The hose is very short so you have to drag the thing behind you cnostantly. Sucking power is really not all good. And it gets degraded by mouthpiece design with extra obstruction and narrow pieces in the airway. Which also makes it pretty hard to get e.g. straws of grass to pass through. Design of the mouthpiece is also such that anything larger than about 4mm requires lifting it to get sucked in. It makes a lot of noise already, but if you attach the carpentry cleaning mouthpiece (which in their defense is a rather nifty idea, but for the small effectivity it adds has the disadvante it wears out carpets/couches/... because the brushes are quite harsh) it becomes really, really loud. If you accidentally suck up dust which is too fine it becomes broken (even more noise, loss of sucking power), though that can be remedied by taking most of it apart and cleaning out with compressed air or perhaps water. Mechanism for sucking in the cable is way too weak.
I get that this all might sound like it's a disaster, but I guess it could work for some people who haven't tried alternatives. After all it does suck up some dust. And it doesn't require dustbags. Still I recommend anyone looking for a vacuum cleaner to look into simpler yet more effective designs. From other things I've used: Nilfisk is really good. Models I've used are simple, just work, none of the complaints from above. I also happen to have a Festool one which I normally use for dust extraction for saws/sanders. While not really meant for it, and pretty expensive, it's still way simpler in design than the Dyson and completely blows it away on all fronts.
