gutter cleaning/compressed air

Place the short end of the J-shaped hook inside the gutter, and turn on the compressor. As you walk along the house, high-pressure streams of air will clean the gutter.
compressor is 15 gal, 6 cfm @ 90psi. Air hose will be about 100'. Enough pressure/volume?

I've been using the ECHO rain gutter attachment on my leaf blower and have been quite satisfied with it's performance.

Of course I'm only operating on a single story dwelling, but I'd imagine you could put two sets together, or lenthen some other way.

Moral of the story. Just use the pipe to slide along the gutter to clean it out. Maybe rig up some type of scoop that fits the bottom of the gutter. Then run water with no high psi nozzle to rinse out the mud, crud, shingle rock, etc that is left and chase it down the downspout. You may have to stuff a hose up a down spout to get it cleaned out. I had to use 1" pvc to meke it stiff enough to hold and work. 1/2" is too limber if you have to go very high.

I don't know how well it works personally as my roof is not very steep and I just use a leaf blower. But, I can vouch for their floor cleaning robot, roomba. It works great.

I predict a pole on a pressure washer long enough to reach your gutters will create too much torgue for you to hold the pole. A long ladder maybe?
