Why buy new when you can buy refurbished @ overstock for half the money?!? This vacuum pulled up so much hair i'm inclined to think we have another dog running around that i didn't know about. I used the old vacuum one last time, and the carpet looked clean, but i think i sucked up 3 times more dirt and hair with my new bissell! In case the person who wrote the review claiming the vacuum was putting out Carbon Monoxide happens to read my review, Carbon Monoxide is a product of combustion, and you should probably realize an electric motor doesn't combust anything. I think the problem you were experiencing is a result of too much carbon DIoxide coming out of your mouth!
