I only run with Extreme poles and Extreme 35cm brushes now. I use my 47 foot Extreme on one job which is a tenement every 2 months. Clean the top, middle and bottom for £66 which takes 30 minutes. Was it worth buying the pole for one job? What it does mean is, if I get an office to clean then I already have the pole inplace and means I can get to work immediately. Reliability seems to be the name of the game that all customers want and if you don't need to wait for equipment to arrive then we are half way there.
