I have an older hot water washer, diesel fired w/ 2 electric motors. I use it for both equipment and whatever else, usually just with cold water but hot water for heavy grease. Quite heavy, I move it from place to place using my Tommy Gate truck lift. With 200 ft of hose, I can wash houses, etc. Also have a smaller Craftsmen gas powered washer. It was ok but not the same as the other one.
