Window Payload combines an onboard chemical tank, on-demand injection, and variable metering with the Sherpa drone’s ground-fed water supply. Apply cleaner when you need it, switch back to purified rinse water, and control the complete touchless cleaning cycle from the ground.

Reach elevated exterior glass while reducing dependence on lifts, scaffolding, and rope access when the jobsite allows.
Switch between chemical application and water-only rinsing without landing to change tools or ground equipment.
Manage the mix, dwell time, water quality, and final rinse instead of relying on pressure alone.
Add routine glass maintenance to your service mix and create opportunities for quarterly and scheduled cleaning contracts.
Compared to 4-6 weeks using conventional cleaning methods.
Estimated savings by avoiding lift-rental expenses.
Workforce compared to 12+ workers estimated for the conventional approach.



The published starting point is 1 part Lucid Clear+ to 50 parts water. Actual metering depends on the pump, injector, metering component, hose length, and nozzle. Do not use Lucid Clear+ at a stronger concentration than its current instructions allow.
Lucid Clear+ is the primary publicly documented solution for Window Payload. Any alternative chemistry should be reviewed for glass compatibility, dilution, handling, rinsing, and equipment compatibility before use.
Existing mineral deposits often require specialized chemistry, agitation, or restoration. Window Payload should not be positioned as a universal hard-water-stain removal system.
Window Payload is intended primarily for routine exterior commercial windows and glazed facades. Coated glass, films, damaged seals, specialty glazing, and adjacent materials should be reviewed before cleaning. Complete a test area when compatibility is uncertain.
No cleaning method should make that guarantee without qualifying the glass, water, chemistry, weather, and process. Properly purified water, correct dilution, appropriate dwell time, and thorough rinsing support a cleaner finish with minimal spotting.
No. Window Payload is a touchless spray system and does not include a brush or squeegee. Some heavily soiled or mineral-stained glass may still require contact cleaning or restoration.
