Query: This vacuum sucks...not!

I can't understand all the glowing reviews for this overpriced piece of crap. It seems as if all the money has gone into marketing instead of r & d as the commercials claim. My 10 year old Oreck is far superior on both rugs and bare floors and my Eureka Mighty Mite blows it away for picking up animal hair.IT DOESN'T LOSE SUCTION BECAUSE IT HAS NONE!!!
