A great investment. The machine is super easy to use and gave great results. It washed and vacuumed the carpet at the same time. Even though the water/shampoo tank is small, I cleaned large rooms quickly. The shampoo has a great smell. This machine is a MUST have, it is useful for quick messes and for large area cleaning. I decided to clean my two stories home every 3 months. Thank you Bissell for such a product and thank you for saving the lovely pets.
