I was hesitant to buy it but I'm glad I did. It's a fairly cheap machine, but it works amazingly. Used it as soon as it came out and my carpets look almost new. Not suitable for stairs. However for the money this is a great product to keep your carpets looking good. If you need something to really remove stains that have been on the carpet for years, this probably won't do the best job removing every last drop. You will want to invest in a more powerful machine for this. I work in a factory and over the course of a few years I've gotten some pretty big black spots from walking around the house. This car pissed her off. Great little car
