I have vinyl siding and a 3-story house. Algae and dirt needs to be
removed (a bleach/detergent mix works fine). What kind of extension
pole (about 20 feet) could be used?

If you have a Karcher pressure cleaner, there is a multisection extension
available. Check Google for sources. I got one a couple of years ago for
about $50.
