Help! Cleaning high velux windows residential

Hello folks, please forgive if I’m in the wrong place or this has been answered. Am a Newby .

I am a householder in Twickenham who hasn’t yet found professional to clean my velux windows that are high ish - set in the sloping roof of a terrace side return. And only really accessible from the inside.

So, attempting this myself. Think I Need a swivel headed squeegee and a longish pole. (Don’t want to do the ladder thing). Any help : advice really appreciated. (And if anyone lives near Twickenham, Middlesex and would be interested in quoting, very welcome to pm me )

Veluxes do flip on their axis so can clean both sides from interior at a pinch - Though it’s tricky.. two person job. One to hold.
