i have a couple of accounts where the flat roof extensions have large raised plate glass skylights that are almost horizontal.i tried with a wfp last month and the results were rubbish as the water runs very slowly off!so tommorrow ill go back to using my trusty trad pole on these windows!
i also have a couple of accounts where its virtually impossible to get the trolley near and i dont have a backpack so i use the trad pole on first floors as gravel/imprinted concrete makes it dangerous with a ladder on my own.
i suppose ive been thinking lately wfp is best but its not on some work!
one stand alone im doing tommorrow im reverting back to trad on as ill be much quicker!

what about you guys?
regards
