Veteran Window Cleaning is featured in this video. Here you will see them cleaning a 9 story apartment complex with a waterfed pole and boomlift. The Bryson Building is located in Los Angeles, CA and is a historical landmark.
Equipment used were Ionic Grafter Poles and RHG EZ Pure.
Disclaimer: Because this was a historical landmark and the frames were in need of repair, their customer felt is was only important to focus on the windows.
