Give steve a ring, you probs could source all the bits cheaper but by the time youve searched for each part, got it delivered, realised youve missed parts etc youll be kicking yourself, at least steve is a window cleaner and youll get all you need in one go, theres always cheaper options out there which youll come to find on this website people making there own brushes, poles, jets etc etc etc, I wish I hadnt lisened to certain things from the start when I came on this forum as I thought I was saving money where as in the long run its cost me,
