I got my Bissell 2 weeks ago and I love it! For those who say it is too heavy- a quality machine is going to have a little weight behind it! It's really not that heavy, and the large cushioned wheels mitigate that a lot. I have had a lot of the "lightweights" and believe me, that's how much suction they have!
I have numerous allergies and this machine is doing a fabulous job for me. It's a great buy! Very well built, solid, and good design; emptying the canister is a breeze. Thanks!
