It changes how you reach height, not the cleaning basics. Soft washing still covers routine organic growth, exterior soil, siding/stucco/masonry, and hard-to-reach elevations. Window cleaning still fits routine commercial glass, curtain walls, touchless-suited properties, and recurring programs. Water repellents still require approved products and substrates, prepared surfaces, and defined coverage targets.

Soft washing may still need another method for heavy oxidation, bonded contamination and graffiti, or surfaces that need deep scraping. Window work may still need lifts or contact methods for hard-water restoration, etched glass that needs scraping or buffing, and damaged coatings, films, or seals. Water-repellent jobs may still need another approach for unapproved substrates, precision decorative detail work, or substantial substrate repair. Use the drone where the surface and chemistry fit; keep traditional access for the rest.

Yes. The Sherpa is built for exterior cleaning companies that already know soft washing, window care, and similar work. It puts a proven spray process at height so operators stay on the ground, which helps you quote more high-access commercial jobs, sell more exterior work to accounts you already have, and cut how often you need lifts, scaffolding, roofs, or ropes. The fundamentals stay the same: qualify the surface, pick the right chemistry, control the application, allow dwell time, and rinse completely.
