I had a large soda stain on my beige carpet from my puppy knocking over my can. I soaked the stain with their pretreatment stuff and cleaned it up with the machine. The stain is gone! I really like the separate soap and water dispenser too. Then, the separate waste water is super easy to empty unlike other machines. I haven't tried the many attachments nor all of the extras but it did a very nice job on my basic carpet cleans so far!
