I purchased the SmartWash because my bissell pet mate quit working. I'm glad I did. The SmartWash is a much better product. First the auto wash as you go forward is fabulous. The brushes clean remarkably great. The machine is light and easy to handle. SmartWash was intelligent to use the auto mixing of cleaner and water. It saves so much time and energy. Along With the super dry feature, suction is awesome. Tanks fill all the way before having to empty which is also a time saver. Overall I love my new SmartWash and recommend anyone to try it!
