Even though my pressure washer was at the lower end of the required range for this product, it still did a great job of cleaning my concrete. It made my full day of work using my turbo tip into just a partial days work, and so much easier!
I used it to clean my concrete patio. It took 1/3 the time as with a nozzle alone and cleaned it almost as good (maybe 90% as clean). Also, it was a lot less strain.
At first unboxing, I was impressed at the sturdiness of the 16.5 inch surface cleaner. I'm glad that I chose to purchase the stainless steel version. It's built like a tank. All fittings appear to be precision machined. I expect to give it a work out real soon on the driveway.
