I followed the instructions on the bottle in order to fill my machine. Unfortunately, even though everything was were it needed to be for the easy-fill components, it still would not dispense the liquid. I had to press the mechanism myself to release the liquid. It was a pain, but not the worst thing in the world. It seems to have cleaned my carpet very well! It changed to a lighter shade which was expected and made it feel so much cleaner! The scent/fragrance of the product is overwhelming for a small apartment. The scent, as it dried, caused me to feel nauseated both times I used it - once right after I washed and the other after it had dried. I don't know what they put in there to make it smell like that, but I would definitely recommend to add another solution to mitigate the smell or for the company to change the scent. I have to spray odor eliminators on the carpet just to be in my bedroom fro longer than 10 minutes. Overall, it gets the job done, but at what cost?
