Much better than our smaller, older pressure washer. The circular head cleans a reasonable amount of surface with each pass. Some "shuddering" leaves a faint dirt mark if you're working on a dark surface and you can't see that when it's wet.
The pressure coming from this washer is really good. I used to clean my car using the pressure washer from car wash station and this product does match and even exceeded the amount of pressure I need to clean up my car. No more paying and I can wash my car at my convenience.
