Instead of working the stains deeper into the carpet, it absorbs them with this special powder. The carpets are dry in minutes and your house smells like oranges for a little while. The only problem I had was that the powder has a lot of alcohol on it, and the fumes sting the eyes a little. Just open a few windows and it will go away as soon as they vacuum.
Pros: fast, got almost all the stains out
Cons: couldn't remove red jello stain, temporary alcohol fumes
