I bought the pressure washer mainly used for the garden. I had stone pillar which was guarded with very dense moss. Without problems I removed the the cleaners just like the old dirt or discoloration. He made everything as clean as as if you had just bought all new. Next, I used it to clean my whole garage. He cleaned the floor absolutely great as well as the entire walls. Stubborn dirt or debris was easily washed away with no problems. Next for what I'm going to use it, is to wash and also because I will certainly be very pleasantly surprised. Therefore, I can give this device without problems five stars.
