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.




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.
