I went looking for a bagless vacuum cleaner that I could get today from a store. By far the best quality model available at any of the major stores was this baby.
It's not as good a deal as the Godfreys electrolux offer: https://www.ozbargain.com.au/node/176335
and if you don't need the vacuum immediately then that is a far better option.
For those who need a quality vacuum today this is a great offer.
Usually retails around the $200 - $240 mark.
EDIT: Just unpacked it and used it. Wow, it certainly does suck :) It is very powerful for a 1600W motor.
What I didn't realise is that the unit comes with 3 separate head attachments: the Turbo head, The non-turbo head and a smaller upholstery head. It also has a curtain brush and a thin corner attachment. I used it for about 20 mins and it didn't turn itself off. So maybe they have improved this model (it's a Zen2, not a Zen)
I have a Vax (non pet) Zen vacuum cleaner. Really good units. Suction still strong today and it has gone through quite a lot.
