For the pricing, sample units run about $18,500, mid-volume orders of 5-10 units drop to roughly $16,200 each, and bulk buys of 20+ come in at $14,800 or so—basically the cost per flight goes way down as you scale up.
It's a 27kg aluminun-and-carbon-fiber rig with a 14s 28000mAh battery, so you get 10 minutes of working time per charge, but what really matters is that 210 bar presure at 10 liters per minute spray flow—that's 3000 psi hitting a 500mm wide swath at 1m/s move speed, covering about 240 square meters per flight if you don't waste time.

Most buyers go with the 10L/min flow because of that it balances cleaning power with battery life, and nozzle angles (0/25/90 degrees) let you switch between flat surfaces like solar panels and vertical glass curtain walls without landing—just flip it mid-air (usually 2-4 weeks lead time for custom nozzle configs).
Actually, we usually have stock on the standdard JT 30L model with the 1.5m spray boom, but confirm lead time if you need the autonomous flight software unlocked—that's an extra $1,200 or so and adds route planning for large solar farms where you'd otherwise burn through 3-4 flights manually.

It's not suited for tight indoor spaces like warehouses because the wind resistance tops out at 10m/s and the effective distance is 2-2.5m form the surfce, so you need open air, but for high-rise building facades or glass curtain walls above 100m, it's better than rope-access crews by a long shot—especially in -10°C to 50°C temps.
Anyway, pricing includes CE, FCC, RoHS, and ISO 9001 certs, and we ship with a remote control plus the hose kit, but the water pump and ground tether aren't in the box—you'll need a separate 210 bar pump, which our company can source at about $2,800 if you don't have one.
We typically ship within 15-20 working days after order confirmation, depending on stock levels. If you need a rush order, let us know and we'll see what we can do.
Yes, all those certifications are included with the drone—CE, FCC, RoHS, and ISO 9001. We'll share the certificates digitally after you place the order.
Our MOQ is 1 unit for the JT 30L, so you can order just one to test it out. We do offer discounts for bulk orders of 5 or more.
The spray width is measured at the nozzle outlet when using the 0° angle setting at full pressure—up to 500mm across. The 2-2.5m effective distance refers to how far the spray reaches from the nozzle before losing pressure, not the boom length.
Keep it in a dry, cool place between -10°C and 50°C, ideally in a case to protect the carbon fiber and aluminum frame. Make sure the battery is stored at around 50% charge if you're not using it for a while.
