I have a length of garden hose in my van for first cleans and FSG cleans. Use it with my pole no need for a sprayer get the water up there with your pole.Its quite a handy thing to have anyway when cleaning soffits, fascias and gutters. saves using so much of your own pure water. Just agitate dirt with brush then spray on normal water with hose. Rinse off with pure. Mind you thats a different topic altogether.
