I purchased this machine to replace a steam cleaner I had used for years. That machine was just not cleaning like it used to. I have a few area rugs and a large den that is completely carpeted with a commercial grade carpet. I thought that I would have to replace all of the rugs due not only age but that I could not get them clean anymore with my steam machine. The area rugs are a light berber. I decided to take a change on this machine since the reviews were great. OMG my carpets all look like brand new. I do have 2 large dogs and even their hair was removed from the carpets. The cleaner came with a sample size bottle which had Scotch Guard in it. Now my house is clean, smells fresh and I have Scotch Guarded the carpets all in one easy step. I do wonder why the detergent/water dispenser was 1/2 the size of the dirty water container. So it required adding before the other was full. But if that is the only thing I am super happy.
