So you're looking at the 30kg class cleaning drone, and honestly, most buyers who've been in this space for a while come to us asking about the JT 30L model specifically — it's basically workhorse for solar farms and high-rise glass. We've shipped hundreds of these, and the first thing people notice is the weight; at 27kg it's not something you just toss in the back of a car, but the alumnum alloy and carbon fiber frame keeps it durable without being unmanageable. What it does is carry either its own tank or hook up to a ground hose, and that gives you some flexibility depending on the job site.
The spray flow is 7.4 liters per minute from teh tank, but if you switch to the hose it jumps to 10L/min, and the pressrue difference is huge — 750psi from the tank versus 3000psi from the hose, so you'll want the hose for stubborn grime on solar panels. Each flight covers about 240 square meters, give or take, and you're looking at roughly 10 minutes of working time per charge on that 14s 28000mAh battery, which means you'll need multiple batteries for a full day. The spray boom is 1.5 meters long with nozzle angles at 0°, 25°, and 90°, and the 720p FPV camera gives you a decent live feed, though it's not 4K — it's good enough to see what you're hitting.
Most buyers go with the 10L/min hose setup for solar panel cleaning because the higher pressure really cuts through bird droppings and dust buildup, but the tank option is actually better for glass facades where you don't want that much force. It handles wind resistance up to 10m/s, so you're fine in moderate breezes, but anything above that and you'll want to ground it — we've had guys try pushing it in 12m/s winds and it's just not safe. Temperature range is -10°C to 50°C, which covers most climates, but below freezing you'll have issues with water freezing in the lines anyway.
Now, one thing that catches people off guard — this drone is not suited for heavy industiral cleaning like oil rigs or chemical tanks; the 500mm spray width is really designed for flat or gently sloped surfaces, not complex geometries. We do have buyers using it for roof cleaning and warhouse skylights, and it works fine there, but the GPS positioning relies on a clear sky view, so parking garages or under awnings are a no-go. The autonomous flight app is pretty intuitive, but you'll want to spend an hour or so setting up the preset paths before your first real job.
Quality-wise, we send every unit with a COA and the CE, FCC, RoHS certs are all current — we usually have stock, but confirm lead time because the 30L model has been popular lately. The warranty is one year, and we've seen very few frame issues, though the pump seals can wear if you're running abrasive cleaning solutions; stick to neutral pH detergents and they'll last fine. Also, the 14s battery is a custom size, so order a spare or two upfront — waiting for replacements can take 20 days or so.
Pricing depends on quantity obviously — for a single unit you're looking at around $8,500, but at 10 units or more it drops to about $7,200 each, and we can do better at container volumes. Lead time is typically 4 to 6 weeks for standard orders, but our company can rush a few units in 3 weeks if you pay the air freight difference. Most buyers ask about the hose length first, then the battery life, and then they always want to know if the app works with Android and iOS — yes, it does, and the remote has a 2km range in open areas.
The JT 30L has a maximum flight height of 100 meters, so it’s perfect for most high-rise buildings up to that height. If your building is taller, you’d need to reposition or use additional equipment.
The 14s 28000mAh battery gives you about 10 minutes of working time per charge. With a cleaning area of 240 square meters per flight, you can plan your jobs around that 10-minute window.
It’s CE, FCC, and RoHS certified, so we can supply the relevant certificates upon request. That covers safety, radio compliance, and environmental standards.
Yes, you can switch between 0°, 25°, and 90° nozzle angles in flight via the remote. The 0° is for straight-on cleaning, 25° for angled panels, and 90° for horizontal surfaces like roofs.
The MOQ is 1 unit, so you can start with just one for testing. Lead time is usually 7–10 working days after order confirmation, depending on stock.
