stiffer pole AND a carbon gooseneck mate.
the normal 45 or 55 degree gooseneck will do.keep it on your pole at all times instead of putting it on just for skylights so your not wasting time when you could be cleaning.
the 90 degree gooseneck is good for solar panel cleaning though on longer poles.
i find the Xtreme poles with carbon goosenecks fantastic for both skylights and solar panels.
