salair

Thank you all for your imput.  My last two vacuums was a dirt devil and a hoover respectively. The dirt devil was a bagless canister vacuum . My blunder was that in trying to save money; I completely didn't consider the fact that emptying the canister and cleaning the filter would would just eject the dust back into the air. The hoover tempo widepath wasn't bad allergy wise, except that it started to fall apart almost immediately after purchase. first went the cover, which I duct taped, then the adjustable wheels, followed by more duct tape,  the attachment wouldn't remain attach, they started disappearing when my kids vacuumed, and finally the roll brush broke.

I don't have much use for the attachment  50% of my floor is covered with rugs and all my furniture was purchase with slip covers. I just wash everything.  My main concern is getting as much dust out of those rugs as possible, my son's allergies is bordering asmatic. With my limited budget, I'm leaning towards the Perfect, but it doesn't seem to have a disposable bag option just a filter. The sanitaire is slightly over my price range. Is it possible to get a coupon to purchase one of these?

Hi. I'm about to buy my second vacuum in two years and I am quite frankly tired of replacing vacuums this often. So I've decided to give the commercial vacuum a try. I need an upright, hepa, bag vac because my son has allergies.
My research have led me to two model.
