Thanks guys.
It would probably be my main pole. I have an 18 foot ecoline pole Pure Freedom supplied me that I'll probably cut down and use for more cramped work, but apart from that I'd be using it full time. A lot of houses on one of my estates have windows set back over garages with sloped rooves, and I need something that will stay as horizontal as possible.
What are the Superlight brushes like to use? They seem very light, do they give enough weight pressure to scrub the windows properly?
Alex, how much do you charge for delivery?
