A precision spray drone for building cleaning and agricultural work.
SPLASH is a hexacopter designed to put water, cleaning solution, or crop treatment exactly where it is needed — on facades, solar arrays, orchards, and fields — without putting people on ladders, lifts, or uneven ground.
The same flight platform can be configured for facade washing or agricultural spraying. Operators change tanks, nozzles, and mission software instead of buying two different aircraft.
Reach walls, windows, solar panels, silos, and industrial exteriors that are slow or unsafe to clean by hand. A ground pump can feed the spray boom through a hose so water is not limited by an onboard tank.
Apply water, nutrients, or approved crop treatments in even passes. SPLASH is built for orchards, vineyards, row crops, and greenhouses with outdoor access.
Flight time, charge time, and daily work windows are designed around real cleaning and farm schedules.
Typical working flight with spray load
Light-load inspection or rinse flight
Fast charge to 90% on a swap pack
| Time specification | Value | Notes |
|---|---|---|
| Working flight time | 20–24 minutes | Spray pump on, standard 16 L agricultural load or hose-fed cleaning boom |
| Light-load flight time | 28–32 minutes | Inspection, mapping, or low-flow rinse |
| Hover endurance | 18 minutes | Station-keeping on a facade or tree line |
| Standard charge | 50 minutes | 0–100% on the dock charger |
| Fast charge | 28 minutes to 90% | Hot-swap pack so the aircraft stays in the air |
| Ready-to-fly after swap | under 90 seconds | Latch, self-check, and resume mission |
| Daily operating window | 6–8 hours | With two to three battery packs and a charger |
| Facade coverage per battery | 400–600 m² | Depends on dwell time and water pressure |
| Field coverage rate | up to 8 ha / hour | Open crop, 5 m swath, multiple batteries |
Propulsion, pumping, and computing share a managed electrical architecture so spray pressure stays stable as the battery discharges.

SPLASH follows a structured loop so cleaning and farm work stay repeatable and measurable.
Scan the facade or field and set keep-out zones.
Choose tank, nozzle, pressure, and flight lines.
Hold distance and flow while the aircraft tracks the surface or crop row.
Change batteries or tanks in under two minutes and resume.
Store coverage, liters used, and flight time for the next visit.
Aerial spray work happens near people, glass, power lines, and crops. SPLASH is designed with awareness and limits as part of the architecture. Final operating rules depend on local aviation, pesticide, and building-access regulations.
Keep the aircraft inside the property and below a set height.
Automatic return on low battery, radio loss, or operator command.
Forward vision and ranging to reduce contact with walls, trees, and equipment.
Pump stops if the aircraft leaves the spray corridor or loses attitude.
Mission software warns and can pause when gusts exceed the working envelope.
Ground spotter recommended for facade work and public-facing sites.
Building operators and growers who need repeatable spray work without heavy access equipment.
Keep exteriors and solar arrays clean with shorter site closures.
Add an aerial service line for high walls and hard-to-reach glass.
Treat rows and canopies when ground rigs cannot enter wet soil.
Share a platform across members for seasonal spray windows.
Wash public buildings and monuments with controlled overspray.
Test nozzles, flow maps, and vision-guided spray with Wiphay.
Pilot programs can evaluate facade cleaning, solar wash-down, or crop treatment on your site.
