Shark Carpet Sweeper Review

Two years ago I purchased the shark 3 speed sweeper for my summer home, that unfortunately, has been discontinued.  I loved it.  This year I purchased the two speed sweeper for my permanent home.  It is horrible compared to the three speed.  It dumps back on the floor almost as much as it picks up.  I would not recommend, and hope Shark brings back it's 3 speed sweeper.
