Rog,
Take a closer look at the clip, time the guy on your watch, look at the economy of movement. Keep in perspective the size of the pane of glass.
Leisurely and fast.
Here you have a pole that can add an extra dimension to trad cleaning, and you are highly dismissive of it

I might be WFP, but I will quite probably get this pole, perhaps it is a gimmick, until I trry it out for myself and learn the techniques of using it I will never know.
In 22 years I have never stopped trying new things or new techniques, how long did it take you to try out the microfibre cloth you will now enthuse about??
You were 2 years behind me on that one, and I raved about them to you a long time ago.
I told you in town the other week how I had developed a very fast technique with a pole for doing large shop windows, even those for which I didn't even need a pole to reach the top edge.
Thank you Unger and the swivel lock handle for that one!
spending out £70 or so on a new pole, squeegee, applicator and a couple of channels may well pay for itself hand over fist in the long run, and if it doesn't? well it's tax deductable innit?
I'm not really getting at Squeaks here, sorry Rog, am really just using you to highlight how all of us should keep an open mind, try new products, keep experimenting.
Trad or WFP...doesn't matter, keep learning, no matter how long you are in the job, there is always something that comes along that will help make your life that little bit easier!!!
