Probably my Drimaster upholstery tool is my favorite tool. Why? Because it's very light weight and requires no valve triggering. You just set the water flow where you want it and start cleaning. It takes a tremendous amount of stress off of the operators' hands and arms. I usually set mine with the water flow almost as far down as possible and it does a great job with the proper chemicals. Also, there is no over spray so it reduces chances of getting water on surrounding surfaces. It also has an internal hose for I think about 6 feet that makes it less clumsy to use by keeping the solution hose out of the way.
