Ive just looked at the 83' building you cleaned, the one I have in mind has one more storey, and it also has 2 other floors that are under these 8 floors, apart from the sides, which makes the 2 side over 100'
Did you get any bend in the pole at the height you was working? would I get enough friction on the glass to clean it or would it be a wash clean?
You have not used a SL2 but you have seen one and felt it, which one if either feels the stronger, or in your opinion would not be up to a job, this high up on a regular basis.
Asos have you a time frame on how long it takes to clean at this height.
