15L Bluetooth battery powered garden sprayer

For traditional knapsack sprayers, operators have to halt work and bend down to adjust flow rate via the tank‑mounted knob, wasting plenty of working time in orchard and farm operations. This upgraded 15L Bluetooth battery powered garden sprayer solves this real‑world pain point with built‑in Bluetooth‑enabled spray‑gun remote control.

Developed for agricultural contractors, orchard workers and sanitation service crews by Crosstec, this battery‑powered knapsack sprayer adopts wireless Bluetooth communication between spray gun and main unit. It is compatible with DeWalt 18V lithium‑ion batteries and fitted with a heavy‑duty diaphragm pump plus 15L industrial‑grade tank. It cuts unnecessary physical strain and workflow interruption during long‑hour field spraying. This model is widely sourced by global agricultural wholesalers, importers and OEM partners for crop care, vineyard maintenance and commercial disinfection projects.

1.Core Selling Points

Bluetooth Wireless Remote Control on Spray Gun

All flow‑rate adjustment and sprayer on‑off operations are realized via buttons integrated on the spray gun handle. Operators can tune spray output while walking forward, without stopping work, bending over or looking down towards the tank body.

Vibration feedback and beep tones deliver clear operation confirmation for blind operation. It works reliably even when operators wear thick protective gloves or hold wet slippery hands. Multiple flow settings can be saved locally on‑board for one‑tap quick switching to match different crops and spraying assignments. No smartphone, App or display screen is required for operation.

Wide Compatibility with DeWalt 18V Lithium‑Ion Batteries

End‑users can reuse their existing DeWalt 18V power‑tool batteries for this sprayer. There is no requirement to purchase dedicated batteries separately, which effectively lowers procurement costs for professional teams and equipment rental businesses. Stable power output supports extended continuous spraying for large‑area field assignments.

Heavy‑Duty Diaphragm Pump Assembly

The robust diaphragm pump delivers consistent working pressure and fine uniform atomization. It is compatible with diluted pesticides, liquid fertilizers and a variety of disinfectant solutions. Compared with ordinary pump structures, it needs less routine maintenance and maintains stable performance under heavy‑duty all‑day field conditions.

Durable 15L Industrial‑Grade PP Tank

The 15-liter tank capacity provides extended spraying coverage while minimizing refill frequency. It is suitable for orchards, vineyards, vegetable farms, greenhouses, and landscaping projects.

Ergonomic Load‑Reduction Backpack Harness

Thick padded shoulder straps and contoured back cushion optimize weight distribution and relieve back fatigue for all‑day carrying. The human‑oriented back frame fits different body shapes and greatly improves comfort for prolonged outdoor spraying work.

2.Application Fields

* Pest and disease control for fruit orchards, vineyards and large plantations

* Liquid fertilizer application and seedling care inside greenhouses

* Landscape maintenance for gardens, lawns and shrub zones

* Sanitization and disinfection for public areas and commercial premises

3.Core Differences

*No Need to Look Down – Always Eyes on Target

Traditional knob:  Every adjustment requires  looking down to locate the knob . When you look back up, you may have missed a section of crop, or the spray gun direction may have shifted.

Bluetooth handle speed control:   Eyes stay on the crop or spray surface at all times.  Thumb operates +/- buttons blindly – spray gun direction unchanged, spraying continuous without interruption.

Advantages:

Reduced missed or overlapping spray areas

Improved spray uniformity

Lower safety risk (especially when working near roadsides or ditches)

*Hands Work Together – Spraying and Adjusting Simultaneously

Traditional knob:  During adjustment,  one hand must leave the spray gun  to turn the knob – spraying stops. If the other hand is holding the hose or pushing aside branches, things get even more chaotic.

Bluetooth handle speed control:   Spray gun never leaves your hand.  Thumb adjusts while index finger continues pulling the trigger. If you need to push aside branches, your other hand is free to help – unaffected.

Typical scenarios:

Orchard worker: one hand pushes aside dense foliage to expose fruit clusters, the other hand holds the spray gun for precise application – while adjusting flow to match different branch densities

Disinfection worker: one hand pushes the sprayer, the other holds the gun – adjust while walking, no need to put down the gun

*Adapts to All Hand Types and Working Conditions – All-Day Comfort

Advantage:   True ergonomic design  – the machine adapts to the hand, not the other way around.

*One-Touch Preset/Memory Function (Advanced Models)

Some Bluetooth handles support two or three preset settings, for example:

Short press "+"  : stepwise flow increase

Long press "M"  : save current flow as preset

Double press "M"  : switch to preset mode

Advantages:

One-touch switch between "fine mist mode" and "jet stream mode" – no need to step through gradually

Multiple users sharing one sprayer – each can save their own preferred settings

Quick recall of parameters for different crops or seasons
