Designed for professional agriculture, orchard management, greenhouse cultivation, landscaping, and sanitation applications, the Crosstec 15L Backpack Sprayer with Auto-Cleaning and Variable Speed combines intelligent spraying technology with practical field performance. Built around a powerful diaphragm pump system and compatible with 18V DeWalt batteries, this sprayer delivers extended runtime, stable pressure output, and simplified maintenance for demanding daily operations.
Unlike conventional battery sprayers that require frequent cleaning and suffer from pressure fluctuations, this model integrates patented self-cleaning technology, variable speed control, and constant-pressure performance. The result is improved spraying consistency, reduced downtime, and longer equipment lifespan, making it an ideal choice for professional users and agricultural distributors.

Traditional sprayers often require time-consuming manual cleaning and provide only a single operating speed, limiting their versatility. The 15L Backpack Sprayer with Auto-Cleaning and Variable Speed addresses these challenges by allowing users to adjust spraying output while simplifying post-operation maintenance.
Whether applying herbicides, pesticides, fungicides, foliar nutrients, or disinfectants, operators can select the appropriate spraying intensity for the task while keeping the internal system cleaner and better protected between uses.
If you're already running DeWalt tools on your farm or job site, you know the drill—you've got batteries everywhere, and keeping track of yet another charger is a pain.
So we designed this sprayer to run on the same 18V DeWalt batteries you're already using for your drills and saws. No proprietary battery platform. No extra chargers cluttering up your workshop. Just grab a battery off the charger, snap it into the sprayer, and go.
The 5.2Ah battery gives you about 5 hours of continuous spraying on a single charge—enough to cover a couple of hectares without swapping. And if you've got a fleet of batteries on rotation, you can keep spraying all day.
We've also engineered the power management to protect both the battery and the pump. Over-discharge protection kicks in before the battery drops too low, which means your DeWalt batteries last longer too. That's a detail most manufacturers overlook—but it matters when you're paying $100+ per battery.
Here's a question we get a lot: "Why do my sprayers keep clogging after a few months?"
The answer is almost always residue buildup. Fertilizers and wettable powders leave a film inside the pump and lines that hardens over time. If you've ever taken a sprayer apart to clean it, you know it's a messy, time-consuming job.
That's exactly why we built the auto-cleaning function into this model. At the push of a button, the system runs a cleaning cycle that flushes out residual chemicals before they have a chance to set. It's not magic—it's just a smarter design that we developed and patented after watching hundreds of farmers spend their weekends scrubbing pumps instead of working their fields.
The result? Customers report spending 70% less time on maintenance, and the pump lifespan averages 1000 hours—about three times longer than conventional models in the same price range.
Different crops and spraying tasks require different output levels. The variable speed system allows operators to adjust liquid flow according to treatment requirements, improving application accuracy while reducing chemical waste.
Need a fine mist for delicate seedlings? Crank it down. Covering a full orchard? Dial it up. The variable speed knob gives you continuous control from 0.9 to 2.9 L/min—so you're not wasting chemicals or blasting plants with too much pressure. One setting doesn't fit all, and with this sprayer, you don't have to pretend it does.The intelligent control system maintains stable pressure throughout the battery discharge cycle, helping ensure consistent droplet size and uniform spray coverage from the first tank to the last.
The 15-liter tank offers an excellent balance between carrying comfort and working capacity. Constructed from durable modified polypropylene, it is designed to withstand demanding agricultural environments.
The industrial-grade diaphragm pump delivers reliable pressure output, long service life, and strong spraying performance for professional applications.

We're a bit different from the typical sprayer manufacturer you'll find on Alibaba. Let me explain what that actually means for you.
We've been building lithium sprayers since 2017—back when most of the industry was still using lead-acid batteries. That head start gave us time to figure out what breaks, what lasts, and what professional users actually care about.
Today, we supply distributors and OEM partners in over 50 countries. Our sprayers are used on vineyards in France, citrus orchards in Brazil, vegetable farms in Southeast Asia, and sanitation projects in the Middle East. That's not a boast—it's just what we do, and it's taught us a lot about different water qualities, chemical types, and user habits around the world.
One thing we learned early: pressure consistency matters more than most people realize. A sprayer that starts at 6 bar and drops to 3 bar as the battery drains is useless for precise application. So we built our constant-pressure system to hold steady from full charge to empty. That's one of our patents—the one we're most proud of.
Oh, and we test every single unit before it goes out. Not a random sample—every one. It adds time to production, but it means our distributors don't get calls about DOA units. That's not just good for them—it's cheaper for us in the long run too.
If that sounds like the kind of partner you're looking for, let's talk.
“We switched to Crosstec sprayers for our vineyard operations last season. The auto-cleaning feature alone has saved our crew at least 30 minutes per day in maintenance time—over a 3-month spraying season, that's a significant reduction in labor costs. The variable speed control also lets us adjust output for different vine densities without changing nozzles.” — Carlos Mendez, Vineyard Manager, Mendoza, Argentina
“We've been distributing Crosstec sprayers across the UK for two years now. The failure rate is remarkably low compared to other Chinese imports we've carried, and our customers consistently praise the battery compatibility with their existing DeWalt tools. They're now our best-selling sprayer line.” — David Fletcher, Purchasing Director, Agrisupply UK
The patented self-cleaning mechanism helps remove internal residue and debris, reducing maintenance time and helping prevent pump blockages.
Yes—as long as it's a compatible 18V DeWalt slide-pack. We recommend the 5.2Ah battery for extended runtime (about 5 hours continuous), but any compatible DeWalt battery will work. Not sure if yours fits? Send us a photo and we'll confirm before you order.
Yes—just turn the dial. You can go from a fine 0.9 L/min mist for delicate seedlings all the way up to 2.9 L/min for heavy orchard spraying. No need to change nozzles for every job.
The sprayer is suitable for fertilizers, herbicides, pesticides, disinfectants, and other common agricultural spraying solutions.
The maximum spraying distance exceeds 8 meters under suitable operating conditions and nozzle configurations.
Absolutely. We've done OEM and private label projects for distributors in over 50 countries. We can work with your design files, apply your branding, and even adjust specs like capacity and pressure settings for your market. Just tell us what you need.
