RUMEX machines help farmers spray less by treating weeds only where they actually appear. Instead of blanket spraying entire fields, our AI-based system detects target plants during operation and applies herbicide precisely to those spots. This saves product, reduces costs and supports practical, sustainable weed control in grassland, row crops and specialty crops.

Technology Overview
- Latest revision : 7/3/2026
- Commercial release date : 30/03/2025
- Application : Weed control, powered by AI that detects monocots, dicots, volunteer potatoes, and crop plants, while distinguishing treated from untreated areas.
Commercialisation Overview
- Technology Readiness Level (TRL) : 10: Market introduction - Full commercial operation
- Units in Service - Global : 201 to 300
- Business model : Direct sales / Distributor network
- Price : $ 151K to $250K
- Ongoing Costs : Yes—there are license fees. The RUMEX (dock/sorrel) algorithm is free for all machine types. For arable farming, one algorithm costs €2,000/year. A second adds €1,000 (total €3,000), and a third adds €500 (total €3,500). For grassland, pricing starts at €500 per algorithm, with an additional €500 for each extra algorithm.

- Countries or markets addressed :
Germany, Netherlands, Switzerland, Austria, Czech Republic, Romania, Ukraine, Poland, Canada, England - for the future Spain, Yugoslavia, Italy, Scandinavian country´s
Performance & Economic Impact
- Estimated ROI :
It depends on the weed pressure, acutal weeding method, pre emergence and after emergence, season workers cost, herbicide cost.
Worst case: 5-7 years
Best case: 2-3 years - Phytosanitary Product Savings :
Since the vehicle is driven at idle speed, fuel consumption is low, and pesticide savings of at least 70%–90% are possible.
- Yield Improvement :
It depends on the pre or after emergence, 1-15% per hectare.
Some use cases went over 20%.
Technical specifications
- Type of solution : Smart/Precision Sprayer Technologies
- Power source : When the front PTO is engaged, it powers the alternator, which supplies the system. A battery acts as a buffer to handle power spikes. In short: it runs on fuel, with no tractor connection other than the front PTO.
- Required Tractor Power :
- Size :
- Metric: Folded: 1.60 (L) × 3.00 (W) × 3.75 (H) / Unfolded: 1.60 (L) × 9.00 (W) × 1.60 m (H)
- Imperial: Folded: 5.25 × 9.84 × 12.30 ft / Unfolded : 5.25 × 29.53 × 5.25 ft
- Net weight : 1,500kg (3.307 pounds)
- Min Farm Size (In hectares) : It depends about the value of the crop, at least 60-80 ha ( 148–198 acres) for onions.
- Productivity : You can operate day and night, so output depends on weather (rain, wind, etc.). At 5 km/h (≈ 3.1 mph) with a 9 m width (≈ 29.5 ft), expect about 3.7–4.5 ha/hour (≈ 9.1–11.1 acres/hour).
- Maximum operating speed : Max speed: 8 km/h ( 5.0 mph).
- Wheel spacing : Adjustable for beds from 1.5–3 m (4.9–9.8 ft).
- Horse power : Min. 40 HP (6 meter machine); 100 HP (9 meter machine).
Functionalities and technologies
- Core Functionality : RUMEX replaces full-field spraying with precise, plant-by-plant treatment. AI-powered cameras detect weeds in real time, while individually controlled nozzles target only the plants to be treated. Designed for reliable field use, it reduces input costs, chemical use, and environmental impact, with integrated lighting, control systems, and tank/pump equipment ensuring consistent performance.
- Software : The core technologies are AI-based camera recognition, real-time image processing and precise individual nozzle control. Cameras scan the field while the machine is driving, the AI identifies target weeds, and the spraying system activates only the required nozzles.
- Connectivity : No GPS required. We only use mapping (with Agrometius, NL) for subsidy documentation.
- Compatible Tools : RUMEX is a front-mounted, tractor-compatible spot sprayer with integrated AI cameras, lighting, and precision nozzles—no extra tools needed.
Development Roadmap
- Next phase : Next improvements focus mainly on algorithms; minor updates include new alternators for work lights.
