If it's a hot pressure washer just be careful because hoses break and hot scalding water getting in your shoes will cause problems. Seen it first hand.
I've seen every episode of Tool Time. Managed to be in the hospital LESS than Tim Allen.
But, life in suburbia is hard and the to-do lists are very long. And I don't half the toys the neighbors do. Need to catch up. They got multiple ATVs with carts and all that stuff.
Don't think I need heated water. If I'm doing it regularly. It's just a lot of brick driveway walls and concrete walkways/patios, garden stone walls, and very long aggregrate driveway. When the runoff from the hill behind us comes over the walls, they start to grow mold and moss. Couldn't use it on painting, because most of the wood trim is 25 feet up in the air. I aint doing that.
