I'm new to window cleaning and having trouble with high angled windows using my extension pole. it seems using an adjustable squeegee just runs the water to the uphill side of the blade, were it shouldnt be !! any better ideas than using a straight squeegee and a rag to do the tops ? I had poor results the other day, hot, dry and the sun ended my practice How about working inside the 8 inch deep window casing on the inside too ? These windows are about ten feet tall on the long side and five feet wide.
