Hi,
I have this squeegee amongst others & can honestly say it is not good for generally squeegee work. It only requires a small amount of pressure on glass for the channel to draw back towards the handle. It is much better on a pole in the locked straight position for downward strokes when you are parallel (behind) but not so good vertical (underneath) to the pole. . It fits all poles i am sure.
The ettore super system squeegee is a far better tool & does almost the same.
