I purchased this cleaner recently to use on the pet stains and the stairs. The fact that it works on spots, and has a attachment so that you can do stairs and high traffic areas such as door ways makes this unit worth every cent. I did one pet spot on the carpet, leaving me with a extremely clean circle, which only demonstrated how dirty the rest of the carpet was. I also plan on using it on the car seats etc. Get more detail about Bissell 1200B SpotBot Hands-Free Compact Deep Cleaner Carpet Cleaner.
