i reckon i would have a job convincing my lot of customers if i was w.f.p . its just that a man on a ladder is seen as ordinary . whereas something new,"new technology" "THE MACHINE AGE " ARRIVING at their door might well get the hackles up .
I think people THINK too much!

When I started with wfp (6 years ago) no one in my area had heard of it, not even any of the other cleaners, however from 500 customers I lost 2.
Sure it took a bit of work convincing them, but every customer got a leaflet explaing what I was doing and I was careful to use the equipment correctly.
After a few months the other cleaners were falling over themselves to be my best mate to learn how it worked. (even one who had threatened me in the past)
It would be so easy to change over now, almost everyone has seen it and are just waiting for the change to happen.
If you have convinced YOURSELF its not a good idea you will never pass it off to your customers.
From a business point of view, wfp is the answer. You can make more money for the same amount of work, or the same money for less work.
Its a NO BRAINER!
