The Most Efficient Window Cleaner In America Might Not Be A Person At All

Founded in Brooklyn in 2021 by brothers Preston and Maxwell Pisano, SKY CLEAN is changing the way America thinks about window and building maintenance. What started as a bold idea has grown into a company servicing all 50 states, using precision engineered drones to clean windows, facades, roofs, solar panels, bridges, water towers, wind turbines, and more.

Rethinking How High-Rise Buildings Get Cleaned

For decades, cleaning the windows of a high rise has meant scaffolding, BMUs, rope crews, and workers suspended hundreds of feet above the ground. It is expensive, time consuming, and comes with obvious risks.

SKY CLEAN asked a simple question: what if the person doing the cleaning never had to leave the ground?

The answer is a fleet of specialized drones operated by fully licensed and insured pilots. By taking heavy equipment and workers out of the equation, SKY CLEAN can reduce setup time, minimize disruption, and significantly limit exposure to height related hazards while covering large surfaces with precision.

A Smarter Clean

The technology becomes even more effective with SKY WASH, SKY CLEAN's proprietary eco-friendly cleaning solution. It quickly breaks down dirt and buildup while leaving behind a protective coating designed to keep surfaces cleaner for longer. The result is fewer repeat passes, less water, and a more efficient cleaning process without harsh chemicals.

SKY CLEAN reports cleaning times improving by roughly 40%, while drone deployment has reduced height related risk exposure by more than 90%.

But the bigger idea goes beyond window cleaning. SKY CLEAN is showing what building maintenance can look like when you replace complicated equipment and high-risk work with precision technology.

The future of keeping America's buildings clean may not involve workers dangling from rooftops or massive machines hanging off the side of a tower. It may look like a drone quietly hovering outside a window, doing the job faster, safer, and with far less disruption.
