Ive got the stats now, them things must be killers to work with, 18kg at 83ft, that would kill somebody if it fell over, thats just stupid, typical Americans "bigger is better". A 45ft one is 6.8kg, thats a joke, I know they have some very good brushes and all but surely a weight like that out "weighs"!!! the good points, they look they were built to give divers back in Victorian times a way back to the surface!!! And no easy to close and open clamps! you need a special tool to open and close them "sorry madame, I've lost my clamp tool in your roses, so I wont be able to clean those 83ft high windows. Spose its better that way, because I have these sudden bouts of full body cramp, and that 18kg pole could just plumet ontop of your childrens heads" !!!!
