So noticed that the pole they were using on the high window has an angle adapter on it.
When first put on pole it was straight later you will notice the angle adapter has been adjusted.
Regarding using it on lower glass wouldn’t be easier to have it on a pole adjusting the angle adapter.
Same goes for scrubbing / squeegeeing.
Need to have the pole extended more also with an angle adapter on it.
So be able to adjust squeegee scrubber to the correct angle.
This way you are able to do clean the whole piece of glass with the pole in one go.
Not stop half way take squeegee off pole and do the rest by hand.
Also having the pole adjusted to the correct length you will not be bending or over reaching.
