I have always loved the Shark products so when I saw an ad for this one I decided it would replace the Bissell that just gave up on me.  This one cleans great and made my white rug white again.  Very lightweight (I'm 77 yy and I can't lug a heavy machine around anymore).  The only reason I gave it 4 stars instead of 5 was the fact that it had to be refilled too often.  Seems like I was pouring out the dirty water and adding clean water after cleaning just a few feet of carpet. Other than that, I loved the way it cleaned and handled.
