I have 3 cats and 2 dogs living with me. One of my cats is a 16 year old who has recently become incontinent. After using the rug doctor and its line of products for quite a while, last year I bought the Bissell Lift-Off. I always used the Rug Doctor products with my Bissell, but last night I used the sample rug cleaner that came with it. What a life saver (not to mention a rug saver)!. Not only will I never use the Rug Doctor again, I will never use their cleaning products. Definitely worth the cost.
