We've seen a lot of crews spend two days just getting boom lifts and scaffolding in place for a building wash, so the fact that this JT 30L hits 100 meters high and does 240 square meters per flight basically changes how you bid those jobs.
It carries a 3000psi stream at 10L/min through that 500mm spray width, and you can dial the nozzle between 0°, 25°, or 90° depending on whether you're through algae on concrete or doing a gentler pass on glass curtain walls.

The 14s 28000mAh LiPo keeps you airborne for 10 minutes per charge — that's tight, so most buyers run at least two batteries per shift and swap them on the ground.
For weight, 27kg is pretty manageable for a two-person carry to the launch point, and the aviation aluminun and carbon fiber frame handles wind up to about 10m/s before you start losing stability.

What it's not great for is tight interior spaces or anything under dense tree canopy because the spray width is fixed at 500mm and you need a clear flight path — that's just teh nature of a 27kg drone.
Stock units ship in 20 days or so usually, and we do custom nozzle setups or different presure ratings if your volume is over 50 units.
Our standard MOQ is 1 unit for initial orders, but we can discuss bulk discounts if you're looking at 5 or more.
Lead time is usually 15–20 working days for a single unit, depending on stock and customization needs.
Yes, all those certifications—CE, FCC, RoHS, and ISO 9001—come included with every unit, and we can share copies upfront.
The standard nozzles are 0°/25°/90° adjustable, but we can swap them for other spray widths or patterns depending on your cleaning needs.
Keep the drone in a dry, cool place between -10°C and 50°C. For the 14s 28000mAh LiPo batteries, store them at around 50% charge in a fireproof bag.
