First it's incredibly heavy & forget about turning it in a hallway. The first time I used it I liked the results. Thought I had finally found the answer to my light carpet / 2 dog situation. But less than an hour later the " rings " were there. You pet owners know what I mean. So I did the hallway again. Slow, small increments. Went over it with the dry feature. Same wait, same rings only larger & more spread out. Did I mention it's really heavy ? Why didn't I return it ? Because I paid so much money. I believed in Bissell. I thought maybe I had so much embedded in the carpet it was just going to take time. Well, I give up ! My neck & back are trashed and I'm just frustrated. I just bought the Shark Carpet blah blah and am waiting for the " rings " to appear. The Bissell will be donated. And I won't be needing any of their products in my life !
