I am still a Dyson convert. Mind you I am not a stick or hand held fan and yes, I haven't used them.
I like the canister models but I recall a recent TV advertisement here at least, Mr Dyson himself said they weren't doing further research on these models (canister)
Here it is. Skip to 22 seconds.

I have a rumba, it cleans my place everyday. I can leave to go to the store and come back home and the place is clean again. I have a bird so it gets dirty pretty quick'
For the record, the Miele has been ok. You can't get powered heads in Europe anymore because of regulations on wattage so the head is powered by air passing over a turbine, handicapping the whole operation a bit. The suck is still much more powerful than Dysons I've tried though.
It's been pretty abused and bashed about with no ill effects (we're renovating our house, I have a shop-vac for heavy duty stuff but the rest of the house still gets covered in construction dust while we're working on it).
Another drawback is the bag consumables end up being pretty expensive. We've tried knock-off brands but the filtration system in them seems to reduce the power of the vac so it's best to stick with the official ones.
renovation vacuuming has results from poor to not good.
after all the demolition is complete and the areas a bare, clase all windows and dehumidify to as low % as possible,
then wait for a proper windy day with the right direction for ideal cross draft action and use a powerful leaf blower to blow out from the cracks and crevices as much as possible.
people sensitive to mold ,mildews, plaster, insulation dusts etc will most def feel the result when projects complete.
i see so much projects where its just crappily swept or vac'ed then the dust and debris remain and are just built over.
