I did this 2 times to my house. I got two aluminum poles that you use for a skimmers in a pool. I got a sprayer and went to home depot and got a really long length of the same size tubing that was on the sprayer. I mounted the wand to the top of the aluminum tube and sprayed with my 30 or 40 foot extension-don't remember. Broke it down to one pole when I got lower. It actually worked great. I couldn't power wash or anything but you just need it wet with the spray away. No precision needed.

I think it was $50 for everything. I did borrow the aluminum poles. We also have bamboo that grows on our property that I have duct taped together to make extensions. I have dormers on my roof so I just leaned out the window and was able to do a decent job. I bet you could lean out of most of the windows on the side and get most of the siding.
