We moved to a new house last month. Many projects to be done. Today I got around to the pressure wash project. The house is 100% brick exterior and white brick at that (not painted but rather white brick.) Due to shaddy areas some of the brick has gotten a bit mossy and/or black in spots. Weeks ago I borrowed a friends Black and Decker little, residential electric power washer. It sucked and did not do well.
I made a reservation and for $50 for the whole weekend, picked up a commercial rental 3000 psi washer with a 9hp honda engine this morning. While there I told the guys at the shop of my project for some brick and some concrete. You see, there is sort of a courtyard in the front walk and again, due to shade, the concrete has a lot of dark coloration here at this house of 38 years old. While talking about concrete the shop guy says, "you need the concrete attachment - I'll throw it in for the same price." Not sure what this is I said, okay.
This is what came with it.

I did not know shuch a thing existed (and that is why I am sharing this here.)
Sort of like a floor buffer. Under the hood is a rotating pair of jets. When you squeeze the trigger the whole thing floats a little on exiting water.
Well, the brick task worked as expected with just the hand wand but when I turned this concrete brush on that is where the amasement happened. My front courtyard walk came out beautiful. The issue came from where to stop???
My house was a custom build in 1973 and is pretty unique. A shared private concrete drive goes back about 250' from the main road and then splits off to my house. Then the concrete widens at the front of my house. I have 35' x 80' of concrete out front or about 2,800 sq ft. In about 8 hrs I covered the entire area with this power washer / floor buffer-ish thing.
All of my concrete is so clean it is almost so white that it is actually hard to look at in direct sunlight. It is the kind of thing that you only do once ever 38 years but boy does it look nice.
All in all, I just wanted to share that this type of thing exisit. I did not have oil spots so I can not comment on how it would work there but my guess is very well.
