Oreck oreck oreck.
I've had their upright and it just keeps going and going and going - had it 10 yrs and that the longest I've EVER had a vaccuum.
My favorite things about it - it will pick up bird seed on a lineoleum floor - doesn't kick it out the back like most other vacs do. Also, it is very light and very powerful.
And best of all - ITS VERY SIMPLE. If you clog it, there is pushbutton releases on the tubing - just take it apart, clean out the clog and right back together it goes.
I've had to replace the roller brush one time when my DH sucked up the edge of the fringe rug with it, new belts and bags, of course, but other than that it's going strong.
I just bought their large green canister not too long ago and it's great too. I moved the old vac out to my sewing hut and use the canister inside and it's as good or better than the electrolux that cost my mom 2-3x as much.
I looked at the Dysons before I got my new Oreck canister and just heard too many things about them wearing out quickly - so went with Oreck since i knew their products are great and are well established.
I LOVE my oreck!!
