This got month old red fruit stains out of my son's carpet! Well, they're mostly out. The two that are still there are extremely light, almost gone. I love this thing!!! It works. My only complaint is the self wash basin. It makes a complete mess. I used the included measuring cup, followed the instructions exactly, and it spilled a good bit of water. Even when I used only half the recommended amount, it still spilled over as soon as the brushes started. I would recommend a basin with higher sides to alleviate the amount of water that is spilled.
