I was able to unpack the cleaner and start using it immediately. Very easy to use and very easy to clean. When I first started using the machine, I noticed very little water coming out and my carpet looked wet and dirty. I pushed down on the front of the machine thinking that some extra weight would help it work better. Something "clicked" into place and then the machine started picking up all kinds of dirt and water. My carpets are now clean and beautiful looking - as if cleaned professionally. Well worth the cost.
