Use of WFP equipment indoors

I am in the process of cleaning a large window inside and outside. It consists of 85 6’X10’ panels. Inside there are 56 additional panels attached at 90 degrees to the other panels. Outside WFP works great. I would like to know if there is a way and what equipment might be available to clean the inside with WFP without the large water flow problem during rinsing, Inside lobby area is carpeted. I have cleaned it once before with scrubber and squeegee on a 40’ lift. I would like to find a better way.

I would appreciate any comments on this subject.

Thanks, JCW
