I loved my Electrolux Oxygen, but I don't have it anymore (nothing to do with the vac). I will get another one as soon as my budget allows. I have a cheapo upright bagless that does a fair job but I hate emptying the bagless vacs.

My mother has a Miele that she adores (she has three cats and three dogs). It's pricey, but she's had it for 15 years and it still works like new.
