This is my first time using a pressure washer and I'm impressed. My house is nearly 60 yrs old and the concrete walkway up to the porch is very old, maybe even original. It had thick moss and grime built up from regular use and the Washington rain. The washer was able to completely detach the moss, which was a pleasant surprise, and clean off the dirt without much effort. The smoother sidewalk in front of our house was much easier to clean, even the moss.
As you can see from the photos, I cleaned my wall around my pool. The photos show the before and after pictures when I washed the wall only half way. I used this without any cleaning products, so it would probably work even better with cleaning products.
This attachment works really well. I've had some trouble in the past washing the rims but this gets rid of all the dirt and gross stuff accumulated on my car.
Started on these steps and it was working well. I also tried on the wood fences and it works. Great buy
