I just picked up one of these over the weekend ostensibly to use in prepping for my epoxy.

My garage floor has many stains and would benefit from a good general cleaning prior to epoxy, and I didn't want the wavy lines like you so often get with other nozzles. For $70, this thing is phenomenal!!!
I did two tests with it, the first was our front walkway/concrete. This tends to get dark mildew like stains on it. I used this head without any detergent or pre-treat. It took YEARS off the look of that concrete. I found a couple tricks here: 1) on concrete it is better to pull it back to you (walking backwards) than it is to try and push. 2) if you go at a slow walk and overlap runs by a couple of inches this thing works like a CHAMP.
It took me approximately 10-15 minutes to do a 3' wide stretch of sidewal about 40 feet long with a 10X10 front porch attached.
I also used this on some minor wood decking. Again, no pre-treat and the PT wood was QUITE weathered. No problems pushing OR pulling on the wood surface, and the results were equally impressive.
Another thing I quite liked here is that unlike your average pressure washer nozzle, ALL the water is contained within the hood, so you get water on the floor, but nowhere else, so you don't need to worry about tools, etc. Because of this design, you WILL generate a lot of gunk on the concrete that isn't blown clear. I just followed it up with a fan-tipped nozzle, but you could rinse it with a hose and squeegee if you were more concerned about airborne water. Also because of this benefit, I will be able to pressure-wash the concrete in my bathroom area to prep for epoxy and not have to sheet everything in advance.
In short, I would highly recommend these for anybody with small to medium concrete cleaning jobs to get done. If you have larger, rent one of the big roller things.

I only wonder how it will tolerate my DeWalt PS which is rated for 3800 psi...
