Hi Joseph
Glad you to see you have joined the forum, we met 2 or 3 at windex and told them about this site
Personally i wouldnt recommend cleaning the upstairs windows with an ordinary pole as i dont think you will get 100% job and will be time consuming getting it right but thats only my view, there maybe someone on here that does it that way and has good results.
Wait to see what repiles you get mate
Wfp is a big step but well worth it when youve taken it you could start out with a backpack, freedom trolley or matts diy site to make your own trolley.
Everything you need to know is on this site, however little your question is dont be afraid to ask
regards
Brett
