We are very happy with our purchase of the Big Green Deep Cleaning Machine. Saves us lots of $ yearly by allowing us to clean our own carpets. The last time I had a carpet cleaning service come out I couldn't even tell my carpet had been cleaned. But, the Big Green Deep Cleaning Machine cleans my carpet thoroughly. I like how substantial the cleaner is and how our carpets dry within a few hours after cleaning (if we use a floor fan). Would buy again and again rather than renting.
