Good price for the Dyson, Kiwi! That model is closer to AUD800 here. I thought my Dyson was called an "animal" too, although it's really a large hand-held rechargeable with a long tube and a power head. One thing I've found with this one's power head (i.e. sweeper brush) as well as the previous, now lost, upright is that the heads pick up long threads (my daughter's long red hair, when she was still living with us) and fishing line (from me preparing lines/rods in the lounge room) and these will stop the power-head turning.
As for colour, Dysons are "funky" at least if they're not pink. The upright was mostly grey with a yellow cord and purple bits (at the time, I saw similar ones with purple cords). The rechargeable is mostly grey with a few blue bits.
I too did a test on carpet with new and old cleaners when we bought the Dyson upright. The previous vacuum was a Vax, a then Australian-made bagged/canister cleaner which is still around as I use it on the back verandah, so it has a hard life. The non-turbo head is nearly worn through as I use it on brick pavers. I will keep it as it's also a very effective wet vacuum. The Dyson picked up a lot of dirt the Vax missed, in carpet. I actually detest carpet and will hopefully limit the amount of it in our house when we retire.
Ouch! AUD800 is $750USD. I have VERY long hair (past my waist actually) and I sew (thread), so I know about that issue all too well

. I used to clean the beater bar weekly on my old vacuum to prevent this issue (borrow one of hubbies pocket knives, and spend 15 minutes cutting everything off).
I too detest carpet

. As renters, we really have no choice on flooring, but if we ever buy a house, the first thing that goes is the carpet! Heck, I'll put down cheap linoleum over having to deal with carpet. If I want something soft, I can use a rug, and if I want my feet warm, that's what slippers are for

Re: What type of vacuum do you use?
I also have a Vax rechargeable cordless which I've had forever. It just lasts and lasts, it's been through several batteries. Its "brush" is a plasticy thing, so it's good for kitty litter and mucky stuff. I use it to clean up the bunny poo. As well as my 'proper' vacuums I have a few dustbuster things. With my menagerie, I am always presented with trails of kitty litter or messes of one sort or another. I have a "good" dustbuster that I use on "clean" people stuff, and a "sacrificial" dustbuster that I use on pet dirt and disgusting stuff.
I have a very old "little green" wet vacuum (guessing Vax is an Australian brand?). Mine no longer sprays solution (I just use a spray bottle), but the vacuum part still has powerful suction and has saved us many a stain on the carpet by being able to vacuum the liquid out. Rarely used, but great when we need it!
