While this is drifting from my original point, Dyson quality is, what I'd consider, upper end discount store quality. I won't even say department store because Sears has some better made canister models.
I have a DC07, DC33, DC16 and DC35. The DC07 is better built than the DC33 without a doubt. The DC33 seems unusually frail at the base. It creaks, frankly the motor doesn't sound too hot, now bear in mind I maintain these and own many vacs and alternate them so it isn't like they had extensive use.
I use the DC33 to do intermittent quick cleaning of my breezeway, the DC07 to quick clean upstairs, the DC16 to do the kitchen. I use a Fantom Thunder on my living room and computer room. Other than that I usually use a Rainbow E Series.
My breezeway is mostly bare floors with a couple of low pile commercial carpet squares I got when Blockbuster was closing. The Dyson is fine for this type of work. The DC07 cleans the surface of the carpet upstairs but deep clean it doesn't. Their brush roller is simply not aggressive enough. If I wait a week and run the Rainbow it is an absolute mess.
As far as industry standard tests, I don't care what the standard is, I could easily demonstrate that the claims are nonsense. Especially removing more dirt claims they are making now. That one can easily be disproven and many YouTube videos already show it against higher end machines.
As far as the cyclonic technology, Dyson designed it, but the Fantom Thunder (regardless of version), in my estimation is the most durable and best designed implementation of it.
