I bought a Dyson, I think the model is number is the 24. It's specifically good at removing pet hair. I also bought it because it is a light-weight model, only just over 5kg if I remember rightly. There's a 5 year guarantee too, so it's not too bad for the price, low maintenance too, with just a monthly rinsing of the filters, though the beater bar is easily removed too, the amount of hair accumulated sometimes has to be cut off. However, I would not be without mine.
