it takes a lot of time and practice, to achieve good results with a trad pole at height, when you soap up , leave a gap at the top, place squeegee on top of glass and make ist pass down (angle squeegee slightly down so soap runs back onto part of window that is still soaped, for next pass , tap sueegee twice on un cleaned part of glass, place at top do 2 part pulls, (pul squeegee down about 2") then complete pass all the way down, continue until all glass squeegeed. for detailing either buy an unger fixi clamp, or wrap scrim round end cone , secure with hair band,practice on your own house , you can check your reults , and then refine technique.
hope this helps
