Dyson DC25 Ball All Floors

We were going to buy the DC07, but decided the DC25 was worth the upgrade....boy, were we right!!!
The main clencher is the ease of using the attachment tools, with the DC25, you just extend the telescoping pole, and, voila! you're ready to go!{the DC07 requires plugging/unplugging to use the attachment tools} I found myself attacking every corner and groove with specks of dirt/cobwebs in it (LOVE this thing for cleaning the ac intake grates and the fins of our air filters!)...most of them without ever having to bend over.
Of course there is the fantastic suction, but then, you expect that from Dyson's reputation...it was disgusting what it got out of our carpet (we have no pets, no kids, and don't wear shoes in the house; I vacuum very regularly, anyways) the first time.
If you don't think you'll use the attachment/tools much, the cheaper models might work for you, but if you appreciate being able to easily attack the tiny corners and grooves no upright can fit into, you're probably dreaming of this model.
The "Ball" feature makes turning and getting into weird corners a breeze, although it may take some people a while to get used to; I've been using a swivel-head mop for years, so I'm used to the motion.  (Customer review: by A.H.)
