That worked awesome and it was done lickety split. All without using a ladder. The only place I didn't get it completely clean was right at the attic vent at the crest of the roof, because shooting up from ground angle, I was afraid of getting too much water into the attic. I'm thinking an 8 foot step ladder for that one small area to reduce the angle, and everything else worked fine with my feet firmly planted on Mother Earth. Those dang spider webs were ridiculously sticky though. Even with high pressure, I had to "walk" them down the wall a ways before they finally came off.
The engine started on the first pull and she ran like a champ. My only two minor complaints would be that the inlet and outlet connections are a little too close together to easily get my hand in for tightening / untightening, especially at the inlet, and that the hose is that same stiff material as the hoses at the do-it-yourself carwash. I think my one upgrade will be to get a 40-50' good rubber hose, and maybe also look at putting an adapter on the inlet connector to lengthen it a bit and make it easier to get to.
