Saw this unit being used in a professional car detailing shop. It was so quiet - I asked about it. Ended up buying one for residential use when I saw a sale. Almost no setup involved - basically comes ready to plug into 120v outlet and standard hose bib. Works like a charm. Only weighs about 75-100lbs, which means I can move it to use to power wash decks, side walk, etc. Would need a sprayer wand extension for that, which would be nice if they included, but easy enough to buy. You cannot run soap through the machine, and only runs with cold water. So if you’re looking for a hot water or steam genie, this is not it. Frankly, I’ve got a wheeled, gasoline-powered pressure washer (with kerosene/diesel burner for steam) for heavy equipment, and this little Adams unit holds its own for all but the heaviest grease/oil type cleaning for dozers, excavators,etc. Needless to say it’s MUCH quieter and cleaner to operate as well.
