hi sparrowteeth,some rubbish been spouted on here at times.YES U CAN USE EXTENSION POLES EFFECTIVELY ON 1ST AND SECOND FLOOR WINDOWS but it takes a lot of practice,it a little slower and u will have to get over fear of ladders cos u will always need them for access over gates and flat roofs etc.i use ladders mainly and poles for awkward and ALWAYS for second floor windows.i have lots of TRAD equipment and poles,vise versa,swivel squeegys etc.fixi clamp for scrim or microfibres.i use poles alot more during the winter months when its wet and slippy for ladders.why do u think they still sell them?u just need practice and the right techniques.why more cleaners dont use them is beyond me.they use them far more in the states.and u dont get soaked.i even rag the odd leaded/frosted window with damp scrim in clamp on pole if windows are done regularly and r fairly clean.NEVER had a complaint in 15 yrs.but majority i clean off ladders cos its quicker but if u work alone on wet/frosty days GET THE POLE OUT

.
1. use good rubber on squeegy
2.use v.dry microfibre/scrim in clamp for detailing
3.use backflip/vise versa where possible
4.dont soap right to top edge unless v.dirty
5.cut in at the top edge and feather if downward strokes
6.have micro/scrim in clamp in pouch ready to swap quickly
dont have t mop too wet unless first time clean,hope this helps pal.best wishes.
also have a 4in scraper handy in case of stubborn bird muck/paint etc to pop on end of pole when needed
