DOCAZOO Docapole 6-24 Foot Extension Pole + Squeegee & Window Washer Combo // Telescopic Pole

It is the sturdiest pole out there. I have many large windows and I did the majority of them in 40 mins normally would take at least a couple of hrs. (moving ladders and such) most poles are too skinny and you can' put enough pressure to clean properly no problem with this unit... Amazon Customer
