A picture says a thousand words, and that's what that squeegee picture does. People immediately associate it with window cleaning.
I personally feel that the same picture of a man with a water fed pole has to be much more detailed before people get the same message. I think it takes longer to get your message across than with a simple squeegee.
I'm 99% WFP so have no axe to grind. With a leaflet you only have milliseconds to catch a potential customer’s eye.
However, IMHO I would say that the leaflet is too busy, there is too much info there - you have to stop and read it, which most won't as it takes effort. I would suggest a brief comment in bold like; INTERIOR & EXTERIOR WINDOW, FRAME, GUTTER & FASICIA CLEANING SERVICE
