Show how we use squeegee fanning off to one side while squeegeeing.
This makes it easier to bend while squeegeeing.
Instead of trying to squeegee standing front onto the window/glass. 
NOTICE AT THE 0.07 MARK HOW WE PIVOT WHILE BENDING.

Standing off to the side and close is also handy to check your work, when I first did commercial work years ago, the cleaning manager came to check my work (on the first clean) and thats what he did and it was a useful tip, shows every fault,
there were none, of course

Wagtails rock for squeegeeing unless they are smaller than standard especially with a Razor red in em,I always end up going back to them.
