Hi, Please to meet you all. I own a handyman business, looking to expand by adding window cleaning, so finding the best way to start up. Great place you've got here, been reading the tutorials, although the supplier links don't seem to work? Was looking at: http://windowcleaningforums.co.uk/t...ow-cleaning-a-4-page-primer.7124/#post-101664 But the links come up with an error, was interested in backpack system, as want to go WFP route. I saw a kit on another website: "hotwash waterfed pole trolley system"? Is this worth it or too expensive for newbie? Cheers everyone.
