We've had powerful 'regular' vacs including a Miele, but they're not a patch on the Dyson. I also can't see what the big deal is with Henrys? I'm sure they're very sturdy, but as a vac the ones we've got at work are shit. Really average suction.

I totally can't fault our Dyson, there's no way I'd ever go back to a normal vac.
