Fantastic unit. This thing can wash an Abrams tank quicker than you can wash your car at home. May be a bit overkill for many jobs, but from soft pine decks to hardened steel, there hasn't been anything I haven't been able to use this on. The quick heat it puts out saves time and money where you would typically need cleaners or degreasers. Setup was a breeze. Connect battery (ships with connecting clips unplugged), add hose to unloader and back to buffer tank, connect your pressure hose to the pre-existing quick connect, start it up, squeeze the trigger and hold on.
