these are upright,bagless with hepa filters
In Point: The Infinity is no where as efficient as a Dyson (DC17), and will not deep clean as well as the new Dyson. The Dyson (DC17), coupled with its new filtration system and aggressive brushroll specifically designed for American carpets will deep clean better than most vacuums under $1000, as well as the previous Dysons on the market (My older DC14 left alot of filth in my carpet that my DC17 vacuumed up....mostly sand and dust).
Dont know if this helps but I just saw a news report here in Southern California today where Good Housekeeping tested all the vacuum cleaners and the Hoover Wind Tunnel out performed all , I found that surprising but that's what Good Housekeeping reported .
