Make your carpet smell better but not so efficient when it comes to cleaning.
I bought this Turtle Wax carpet and mats cleaner/ odor eliminator because my wife spilled some soft drink and soup in my car.  I've sprayed it and let it sit there for 5-10 mins. Then spent more than 30 mins scrubbing the carpet and it barely gets any dirty thing out.  More importantly, the brush only goes vertical and it can move around easily.  Also, you would need to special wet vacuum to dry it out.  Don't do it without a vacuum in winter because it is not going to dry out. The excessive moisture might get moldy.  It does make it smell better.
