PW for high rise window cleaning

Hi guys!
I need your help with one question.
I’m doing rope access and window cleaning more than 4 years.
I got a 33 story building for next season for window cleaning.
Building is new(5 years) and nobody washed it before me.
Problem is, there balconies done like chest desk. And there no holes or anchor under the balconies and windows under the balconies impossible to reach even with poles, because there also lots of Juliet windows.
I thought I can use there stage and WFP. But it is still too far and Juliet’s can not be done.
Question is, is it good idea to use Pressure Washing for windows? If yes, can I use Pure Water thru the Power Machine?
Thank you for your attention!
