My husband was skeptical and wanted to call a professional to try and save our carpet. I ordered it anyway :) and it has transformed our carpet. Everything they say on the infomercial is true. I thought I had to replace my carpets but they have new life. It shaved AT LEAST 10 years off the life of my carpet if not more. It pulled up YEARS of dirt and grime that was buried deep. I HIGHLY recommend this carpet cleaner. It is worth the investment. You'd be crazy not to buy this.
