I have already used my cleaner, and it works so well! I have 2 dogs & during the 4th of July with the fireworks, my dogs got so worked up they were vomiting. I cleaned the spots by hand, but it wouldn't come totally clean. With this machine, I was able to pretreat the area and then clean the area with the machine and it came right out! This carpet cleaner is a must have if you have pets!
