Robots are cleaning skyscrapers right now.
This is no longer a concept video. A robotic system is cleaning the windows of a 45-story Class A tower in Manhattan full-time, riding the building’s existing washing cradle and working roughly three times faster than a human crew. For building owners and facade contractors, the question has shifted from "is this real" to "does it pencil for my building."
Ozmo
The deployed leader
Skyline Robotics’ Ozmo is the system on Manhattan towers today — a Kuka arm on the building’s existing BMU cradle, guided by LiDAR and force sensors, supervised by one certified rooftop operator instead of a three-person crew.
Bravo
The facade-coating cousin
Different job, same logic: PaintJet’s Bravo automates large exterior painting from standard lifts — worth knowing if your facade needs coating, not just cleaning.
How the economics work
Facade cleaning robots are sold as robot-as-a-service — you contract the cleaning outcome, not the machine. Pricing scales with facade area and schedule. The value stack: roughly 3× the cleaning speed, one operator instead of a suspended crew, no fall exposure on the wall (which insurers notice), and consistent quality on every pass. The labor context matters too: three-quarters of US window cleaners are over 40, and the trade is not replenishing — automation here is filling a shortage more than displacing workers.
Best-fit buildings today: towers that already have a building maintenance unit (BMU/cradle), glass-dominant facades, and recurring cleaning contracts. Complex ornamental facades and buildings without roof rigs remain human territory for now.
What building owners should ask vendors
Four questions cut through the pitch: Does it work with our existing BMU or require rigging changes? What are the wind and weather operating limits? Who certifies and supplies the rooftop operator, and what does local regulation require? And what does the service contract cost against our current cleaning contract on a per-year basis — including the mobilization visits? Get those four answered in writing and you can make a real decision.
