hi Peter, like the idea, may well be interested in one.
This is'nt a knock at you, but whenever I see vids or pics of wfp's in use its always on easy windows of semi's lol 
The houses I cleaned today have georgian box bay windows, with shrubs in the garden so I'm not up close to them and have to angle the brush sideways from the pavement to get at them! how would your pole cope with work like that? would it suit that kind of work?
thanks
Simon
Hi Simon,,
It is probably because the highest percentage of windows are how you described. If I have the time I will see if I can get some footage of some awkward stuff.
Now a more honest answer...I think most people doing the video's myself included want to show the product in the easiest scenario possible, they don't want to show any sort of struggle like the struggle you may have had today. Although you managed probably quite easily today, it would not look as good on a video had you been cleaning a simple semi.
People buying systems may ask if a particular pole is easy to use at a particular height, and I usually tell them it is but not as easy as it is at a lower height.
In answer to your other question I shouldn't think the windows you described that you done today should be a problem.
Peter
