Hi derek and robin, thanks for your replys.
I  had thought about cleaning conservatory roofs  with one of them wfp's, would a wfp be any good for this service and what  price do  they range from..As for cleaning peoples windows, there  would be no chance me getting up a ladder to get to them awkward spots a wfp can't get to. I  go dizzy when i wear thick socks. Also i would'nt want to step onto someone elses feet, even though i know that i'd probably do a better job, regards shaun.............
