Designed for professional crop care, orchard maintenance, greenhouse farming, landscape upkeep, vehicle washing and public sanitation tasks, the newly‑launched 16L New 3-in-1 Backpack Sprayer With Self-cleaning Function merges innovative dual‑pump design with reliable field‑proven performance. Fitted with both a water pump and an extra air pump, this upgraded unit supports multiple working modes to handle diverse daily operational requirements, while keeping user‑friendly operation at its core.
Different from standard battery‑powered sprayers that only provide basic liquid spraying, this innovative model adopts a dual‑pump structure and one‑touch mode switching function.
When both water pump and air pump run with cleaning agents added, it produces rich foam for car washing and surface cleaning work.
Without detergent, activating both pumps turns liquid into fine mist, perfectly suited for disinfection, pest control, dust suppression and epidemic prevention assignments.
If you switch on only the water pump, it works as a conventional sprayer for watering plants and routine surface cleaning.
Boasting flexible multi‑mode output and simple one‑key function toggle, this newly‑developed upgraded sprayer delivers powerful all‑round capability. It stands as a highly practical solution for on‑site operators, commercial service crews and agricultural distributors.

Most standard backpack sprayers only support basic liquid spraying with limited functionality, forcing users to buy separate devices for foaming, misting and regular spraying work. Our newly‑upgraded 3-in-1 16L backpack sprayer solves these pain points by integrating dual‑pump design to deliver three working modes via simple one‑key switching, greatly expanding application flexibility.
Whether you need foam washing, fine fog disinfection, pest control, dust suppression, plant watering or general‑purpose cleaning, operators can quickly toggle to the correct mode without switching equipment. This multi‑functional unit keeps internal components well‑protected and cuts extra equipment investment for both field crews and business owners.
If you already use DeWalt power tools on farms or job sites, you are familiar with the hassle of managing extra batteries and separate chargers.
This sprayer works with existing 18V DeWalt slide‑in batteries for drills and saws. No special proprietary battery system is required, and no additional chargers will take up space in your workshop. Simply take a charged battery, click it into position, and you are ready for work.
A 5.2Ah battery supports roughly 5 hours of continuous operation, enough to cover several hectares without battery replacement. Rotate spare batteries to sustain non‑stop work throughout the whole day.
Advanced power‑management circuitry protects both battery and pump modules. Over‑discharge protection activates before battery voltage drops too low, extending the service life of your DeWalt batteries — a thoughtful feature many competitors ignore, especially valuable given the high cost of original tool batteries.
Equipped with a Bluetooth remote controller fitted directly onto the high‑pressure spray gun, it wirelessly pairs with the main sprayer host. Note: Bluetooth connection is only between remote controller and unit; smartphone pairing is not supported.
Users can conveniently adjust flow output via six‑speed gear adjustment right at the spray gun, without walking back to the main unit to tweak settings. It brings huge operational convenience during long‑hour field work.
Equipped with independent water pump plus additional air pump, this new‑generation sprayer realizes three practical operating states with one‑touch mode switch:
*Foam mode: Run both water pump and air pump with cleaning agent added. Output thick foam ideal for car washing and surface deep‑cleaning.
*Fogging mist mode: Run both pumps without detergent. Liquid turns into ultra‑fine fog, perfect for disinfection, pest extermination, dust suppression and epidemic prevention.
*Standard spray mode: Activate water pump only. Operates as a regular sprayer for plant watering and daily surface cleaning.
No extra tools or complicated adjustments are needed to switch among modes, making complex multi‑task jobs much simpler.
Different jobs call for different flow volumes. Combined with the 6‑gear remote flow adjustment, users can adjust output flow freely to match task requirements, boosting accuracy and reducing material waste.
Turn flow down for delicate young crops; turn it higher for large‑area coverage. Continuous flow adjustment helps avoid over‑spraying and material loss.
Intelligent electronic control maintains steady pressure even as battery power decreases. It guarantees uniform droplet size and even coverage from the very first tank through to the final tank of liquid.
*Stable spraying output
*Uniform atomisation effect
*Minimal pressure fluctuation
*Better overall working performance
The 15‑litre tank strikes a good balance between comfortable backpack carrying and sufficient working volume. Built from tough modified polypropylene material, it stands up to harsh outdoor working environments.

We stand apart from ordinary sprayer suppliers you commonly meet on B2B marketplaces. Here is what our difference means for your business.
We began developing lithium‑battery powered sprayers back in 2017, when most competitors still relied on lead‑acid battery solutions. This early‑mover advantage allows us to fully understand component failure modes, real‑world durability limits and genuine requirements from professional end‑users.
Today we supply distributors and OEM partners in over 50 countries worldwide. Our sprayers are widely deployed for French vineyards, Brazilian citrus orchards, vegetable plantations across Southeast Asia, and large‑scale sanitation projects throughout the Middle East. Rich field experience enables us to adapt products for diverse local water conditions, agrochemical formulations and regional operator habits.
One key insight we learned from field tests: stable pressure performance is extremely critical for precise spraying work. Many sprayers suffer severe pressure drop as battery power drains, ruining accurate application. Therefore we developed our proprietary constant‑pressure patent technology to maintain consistent output from full charge until battery depletion.
Besides, every single unit undergoes complete full‑function factory inspection instead of random sampling. Though it lengthens production cycles, this strict quality check drastically reduces DOA (dead‑on‑arrival) complaints for our distribution partners, which brings long‑term cost benefits for both sides.
If you are seeking a reliable, field‑tested sprayer manufacturing partner, feel free to start our conversation.
“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.”
