Perfect size, came pre-assembled. I'm impressed with the sealed bearings that the rotating nozzle use. They just have a quality feel. I also like the max psi and gpm, as my pressure washer has a higher rating and this accommodates it.

I was encouraged to buy this, and I'm glad I had my listening ears on! This device cuts your cleaning time by 50-60% when you are doing driveways or sidewalks. Remember to go slow and steady in both directions and you will be amazed!

I just purchased this item and used it right away with excellent results. The item is perfect for what I purchased it for. I plan on using it for many years to come.

We just cleaned our deck and used deck cleaner and scrubbed and rinsed it. Did an ok job. Used the 12" surface cleaner and it cleaned 100 times better. I love this thing

This attachment is amazing. What a time saver. I should have purchased it years ago. I use it to clean concrete surfaces around my pool and it does a tremendous job.

Easy hookup and easy to use make quick work of big jobs. It handles the big cleaning jobs in a snap. WOuld recommend. Only wish I had the max pressure. I think it would be even better.

Very sturdy and well built. Makes pressure washing my driveway and pool deck a breeze! Definitely a BIG time saver. (I recommend spraying some silicone on the bearings after each use and before storage to keep them from getting stiff)

I have wanted one of these for a long time. I am not disappointed. The quality seems good. Stainless steel so it won't rust. Casters roll good. It thoroughly cleans my patio with ease and little mess.

This 16.5 inch surface cleaner worked great. Cut the time in half to clean the whole driveway and did a great job. Why easier than wand and no streaks. My honda pressure washer is 2700 psi and 2.3 gpm and worked perfect. Would definitely recommend.

Wow! this surface cleaner worked great. It was easy to install on my Gas power washer gun with no effort. The cleaner worked as advertised, the rotating jets underneath the housing cleaned efficiently and with ease. I was able to clean my front sidewalk, front porch landing, and walkway within 30 to 45 minutes. The concrete walkway and side walks were grey and now they are back to their former color. The surface cleaner was a lot easier than using the sprayer tips on the long surfaces. I would definitely recommend the product to my friends. In addition, the price was great.
