Hi all, I took on a round from a retiring co-worker last September that I currently clean traditionally. I have an issue with a few windows that involve standing on steepish peg tile bay roofs that are only possible with one hand gripping the cill. I am not looking to go totally water fed pole as I'm currently working out of a Focus estate that I have to share with my wife, the round isn't big enough and I don't have the spare time to take on much more so I can't justify buying and running a van. I thought the cheapest solution might be to buy a backpack system for those houses where the pitches are a bit dodgy. I have a friend with a water fed pole business that said he could give me the water I need so what I need help with is selecting everything I need to get me set up and anything else I haven't considered. Thanks for any advice.
