What the spreadsheet misses

Güvenlik
Takes people off ropes and lifts for routine washes, the main reason buildings try it.
Kalite
Soft-wash rinsing is not squeegee-clean glass; ask for before and after photos.
Esneklik
Rope teams also inspect sealant and fix things.
Edge cases
Wind, tall towers, dense downtowns and airspace rules limit drones.
Customer experience
Tenants prefer not having a person at the window.
Jobs and redeployment
Rope access shifts toward inspection and repair.
Mevzuat
Drone pilot certification (FAA Part 107 or local equivalent), tethered-flight and water-runoff rules apply.
