What Is Drone Soft Washing?

Drone soft washing combines low-pressure cleaning with aerial delivery to safely remove mold, algae, and grime from buildings.

Drone Soft Washing: Definition

Drone soft washing is a cleaning method that uses an unmanned aerial vehicle to apply low-pressure cleaning solutions to building exteriors, roofs, and other elevated surfaces. It combines the chemical effectiveness of traditional soft washing with the reach and safety advantages of drone delivery.

Where traditional soft washing still requires workers on lifts or ladders to apply chemicals above ground level, drone soft washing eliminates height work entirely. The operator controls the application from the ground while the drone handles positioning and spraying.

How Drone Soft Washing Differs from Pressure Washing

Pressure washing relies on water force (measured in PSI) to blast contaminants off surfaces. Drone soft washing takes the opposite approach:

  • Low pressure, high chemistry: Cleaning solutions do the work, not water pressure. This prevents surface damage to stucco, wood, painted surfaces, and roofing materials.
  • No surface contact: The drone never touches the building. There are no squeegees, brushes, or contact points that could scratch or dent surfaces.
  • Controlled application: Operators can adjust chemical concentration and spray patterns in real time based on what the onboard camera shows.

What It Handles

Drone soft washing is particularly effective for:

  • Mold and mildew removal on siding and stucco
  • Algae and moss treatment on roofs
  • Organic stain removal on concrete and masonry
  • General grime and pollution buildup on commercial facades
  • Bird droppings and environmental debris on solar panels

Why Operators Are Switching

The shift from manual soft washing to drone-based delivery is driven by economics. A drone soft wash crew typically consists of two people: one pilot and one ground support. Compare that to a traditional crew of three to five workers plus a boom lift rental at $500-$1,000 per day.

The Sherpa Drone is built specifically for soft washing applications. With financing from $2,500/mo, operators can add drone soft washing to their service menu without a large upfront capital outlay.
