Window cleaning system

The new Sky Pro window cleaning system from NuStar Inc. is a completely self-contained, self-climbing washing system that operates from existing roof rigs, davit arms, tracks, or from the Sky Pro 4-Wheel steering rig. The Sky Pro system cleans windows, frames and the entire building. The patented pendulum design allows the Sky Pro system to wash high rises completely from the top of the building without ground lines, hoses or cables.
