Window Payload

Rinse, Wash, Rinse. Done.

Add on-demand on-board chemistry to the Sherpa drone.

Turn high glass into ground work

Meet the Window Payload

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.

Safer
Keep more work on the ground

Reach elevated exterior glass while reducing dependence on lifts, scaffolding, and rope access when the jobsite allows.

Faster
Move faster between steps

Switch between chemical application and water-only rinsing without landing to change tools or ground equipment.

Consistent
Control the cleaning process

Manage the mix, dwell time, water quality, and final rinse instead of relying on pressure alone.

Recurring revenue
Build recurring window work

Add routine glass maintenance to your service mix and create opportunities for quarterly and scheduled cleaning contracts.

Chemistry first. Force last.

A drone gets the application to height. The result still comes from the right chemistry, purified water, appropriate dwell time, and a complete rinse.

By the Numbers

Proof from a real application

At Baltimore’s historic Domino Sugar Factory, Ryan Godwin and Godwin Facility Services used the Sherpa drone to complete a large-scale exterior cleaning project while the active facility remained in operation.

Built around the clean

Control chemistry without contaminating the rinse

The Window Payload keeps cleaning solution at the aircraft, separate from the water supply below, so operators control exactly when chemistry hits the glass and when it doesn't.
2-quart onboard tank
Carry the cleaning solution on the Sherpa drone instead of premixing it into the ground water supply.
On-demand wash and rinse control
Activate chemical injection when it is time to wash, then turn it off and return to a water-only rinse.
Variable metering
Use matched metering components to configure the chemical ratio around the pump, hose, nozzle, and cleaning instructions.
Separate purified-water supply
Keep the rinse water separate from the cleaning solution so purified water remains available for the final pass.
Configurable injection system
Select an injector configuration matched to the validated pressure and flow range of the ground equipment.
Battery or continuous-power operation
Use batteries for shorter or more distributed work, or pair Window Payload with a compatible Power Tether configuration for longer cleaning runs.
How it Works

Three steps. One continuous workflow.

Keep the cleaning cycle moving without landing to change tools or reconnect ground equipment.
01
PRE-RINSE
Start with a wet surface
Pre-wet the glass and rinse away loose contamination before applying chemicals.
02
Wash
Add chemistry on demand
Activate Window Payload, apply the chemicals, and allow a dwell time without allowing it to dry.
03
FINAL RINSE
Switch back and rinse clean
Turn off chemical injection and rinse the surface thoroughly with properly purified water.
Lucid Clear

The right clean starts in the tank

Lucid Clear is the featured chemistry for Window Payload, helping loosen everyday soil during the wash while keeping purified water separate for the final rinse. Shop Lucid Clear and the rest of the Lucid Bots chemical lineup.

Common Questions

Frequently Asked Questions

What is the recommended Lucid Clear+ dilution?

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.

What cleaning solution should I use?

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.

Can Window Payload remove hard-water stains?

Existing mineral deposits often require specialized chemistry, agitation, or restoration. Window Payload should not be positioned as a universal hard-water-stain removal system.

What types of glass can it clean?

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.

Will every window dry without spots or streaks?

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.

Does Window Payload touch the glass?

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.
