I seen another window cleaner when I was out laying slabs yesterday. ( Crystal clear cleaning ) wanted to go over and ask him if I could have a shot of his WFP. Just to see if I liked it. Shame I was covered head to toe in sand and mud or I would have went over. Im seriously considering getting a trolley system as I think it could get a part of my round done quicker. Whats your thoughts? Could anyone recommend a system?
