Gazza, I wasn't meaning you would clean 1 top window then the one underneath, then back up to the top window. What I was meaning that if there is two or three top windows you would clean these first, then you would drop the pole to the window underneath the last top one you had just cleaned.
Yes and by the time I get to the bottom windows the drips if any have stopped, and that is my whole point, if you don't use too much water then there is no problem cleaning the window underneath the one you have just cleaned. And surely it is quicker cleaning the one you just cleaned, than to walk to the one underneath the first one you cleaned. Might not be much time but it all mounts up.
Years ago when I first started cleaning windows my mentor used to clean the front windows on a house, then he would walk round the back of the house with the ladder, only to return back to the front to get his bucket. I couldn't understand why he never took it with him in the first place. Again not much time, but over the course of the day it adds up to a considerable amount.
