Come on Guys.
He is very obviously a wfp newbie who doesn't trust wfp to do a good job.
I would hate to see a video of my early efforts at cleaning wfp especially with a Fiberglass pole and later in earnest with an Unger Teleplus ali pole and heavy Vikan brush. In fact, if there was one I certainly wouldn't put mine up on YouTube.
Lets look at the positives.
I'm sure in time he will learn from experience that he doesn't have to work that hard and spend that amount of time on a first clean. I hope he will also learn to find a more suitable place for his squeegee in this van and assign it a tool of much less importance. I think Nathan's comments on YouTube are correct, albeit a little harsh for a proud newbie to swallow, when he says to pick one method and stick by it. (That householder will want his/her windows done both ways in future. He's made a rod for his own back.)
I hope he will learn to handle to pole more comfortably and hence look more professional to us looking on as old hats. But if I was the owner of the house I would see a young hard working cleaner doing a good job.
He looks a very presentable young man, clean and neat; a total opposite to me. I can only describe myself as looking like a tramp, before I eventually visit the hairdresser, and bib and brace overalls so my trousers don't fall down when I'm working etc.
He has a Gardiner pole and a sill brush, so that good!
The only way he is going to start to trust the system is if he does the job, walks away, and comes back a couple of hours later to check on the results and correct any issues. Once he sees that there are no issues then he will stop coming back and trust the first clean. Its a learning curve.
