Heavy-Duty Cleaning Drone with 100m Flight Altitude - Ideal for Wind Turbines and Bridges

Actually, it's the 3200 PSI that usually gets people's attention first—most cleaning drones top out around 2000 PSI or so, and that extra headroom makes a real difference when you're blasting years of grime off wind turbine blades or bridge girders at 60 meters up.

The flight time is 17 minutes and 49 seconds at that altitude, which sounds short until you realize you're not hauling a hose up there—the 100-meter water pipe stays on the ground, 5800 PSI, and the drone just carries the nozzle and the pump assembly, so basically all the weight is in the battery and frame.

We've found most buyers go with the 25° brass nozzle for general work, but you get four options (0°, 15°, 25°, 40°) in box anyway, and switching them out mid-job takes about 30 seconds—just don't use the 0° on anything delicate unless you want to etch concrete.

One thing that's not in the spec sheet: the 36-inch carbon fiber folding props are surprisingly quiet for a drone this size, which matters if you're working near office buildings or residential areas where noise complaints can shut down a job fast.

Lead time is usually 4-6 weeks for the JTC 20, but we do keep a handful in stock for urgent orders—just confirm availability before you commit, because the 14S 28000mAh smart batteries (over 600 cycles or 2 years) are built to order in batches of 50 units or so.

It's not great for fine detail work like window cleaning on historic buildings—teh spray width is fixed at 50mm, so you'll overspray onto frames and sills unless you're really precise with the H12Pro controller's 5.5-inch screen feed.
