Has anyone ever used a telescopic ladder while window cleaning. I have just seen a Youngmans telescopic ladder and it strikes me that it could be useful for some of the more awkward ground floor windows, for example, the type that sit quite high from the ground and even with a footstool you cant reach the top of the window. I would never think of using one for first floor windows. Heres the link. There is a video too: http://www.midlandladders.com/products/Youngman_3_8m_Telescopic_Ladder-510-138.html Or are they just a load of old ****?
