For an additional six or seven bucks in parts, my very talented son had this model up and running in a couple of days after taking it apart and regreasing it.
So far we've cleaned some long overdue dirty house siding, the driveway, an old lawnmower, all the first floor cottage blinds (out on the clean driveway), and the Generac, all in the first week, and I'm probably forgetting something!
Works with a garden hose, and we didn't even use any soap, just plain water. Worked like a charm. It takes up very little space in the garage, too.
What a money saver this thing has been already.
