Bought this a few days ago. Used for the first time today. Took all of 30 seconds to pull it out of the box and hook up to my pressure washer wand. Cleaned half the inside of a garage that had caked on and ground in dirt/magnesium/salt from winter roads in about 10 minutes. Huge difference. Thrilled with it. Seems to be made very well, solid, stainless steel, and the casters are a great touch.
I used this Westinghouse Surface Cleaner along with my WPX3200 Pressure Washer to Clean my Concrete Pool area and it did an awesome job. Very powerful and easy to use.
I purchased just a few weeks, this Westinghouse 16.5 works perfectly with my new pressure washer, only purchased a 3200 psi. but this tool works perfectly. I did purchase an extra 50 foot line for the washer as you will need it to continue with your project without moving PW. If on the fence, buy it as it will seriously cut down your work time.
