AX-1 vs Vitirover

Two weeding machines, one verified table. Every figure below is sourced and dated; vendor claims are labelled and kept apart from independent results.

Kilter AS · Norway

Norwegian ultra-precision weeding robot for open-field vegetables — an AI vision system detects individual weeds and a patented Single-Drop nozzle (SDT) fires one micro-droplet of herbicide directly onto each weed at 6x6mm resolution, cutting herbicide input by a manufacturer-claimed average of 96.6%. Independently tested by Wageningen University & Research at over 99% spray-drift reduction (Dutch DRT99, the system's highest class), and commercially deployed since 2021 across Norway, Sweden, Germany, the Netherlands and Australia, with a 2025 Kubota partnership now expanding EU dealer-network sales.

Best for: Open-field vegetable and root-crop growers (carrots, onions, beets, celery/celeriac, spinach, salads, parsley and similar) in Norway and neighbouring EU markets who still spray herbicide and want to sharply cut volume and drift without switching to purely mechanical or laser weeding.
Vitirover SAS · France

French solar-powered micro-mower for vineyards, orchards and agrivoltaic sites — a 23–27 kg swarm robot that grazes vegetation at ~500 m/h, up to 16 h per day on sun and Li-ion. One 'shepherd' operator manages up to 50 robots from the Viticloud dashboard; born at Château Canon La Gaffelière in Saint-Émilion and sold outright or as Robot-as-a-Service.

Best for: Vignerons and orchardists wanting chemical-free under-vine and inter-row vegetation control with near-zero energy cost, especially as a managed fleet across parcels or solar farms.

Business modelBuy — direct from Kilter AS (Langhus, Norway) via a consultative sales process (farm details submitted for a quote; no public price list), or through regional distributors such as Croplands (Australia). A Kubota partnership (announced at Agritechnica 2025) is expanding dealer-network sales in Germany and the Netherlands through 2025-2026.Buy, or VAAS annual service subscription with fleet shepherding
Ongoing costHerbicide/bio-herbicide refills (any crop-registered agrochemical usable in a boom sprayer, e.g. pelargonic acid); Single-Drop nozzle module (SDT-N2) wear parts. Specific service cost figures not disclosed.VAAS: €2,100–€3,100 per robot per year; blades and wear parts if owned
Key outcome
Best verified resultSpray drift vs. a conventional reference sprayer
More than 99% spray-drift reduction — qualifies for DRT99, the highest class in the Dutch drift-reduction classification system · independent
Herbicide use for under-vine vegetation control
Continuous chemical-free robotic grazing at 5–10 cm cut height · vendor
EU context
CE markingNo explicit CE-marking statement found on Kilter's public materials; the AX-1 is sold and in active commercial/pilot use in EU member states (Sweden, Germany, Netherlands) and passed independent Dutch DRT99 spray-drift certification (WUR/TCT)CE status not published; French manufacturer selling commercially in the EU
Machinery RegulationNot explicitly addressed by the manufacturer; as an autonomous field-spraying machine placed on EU markets, would fall under the autonomous-machine provisions of Regulation (EU) 2023/1230 if formally assessedPlaced on the EU market by Vitirover SAS; Regulation (EU) 2023/1230 autonomous-machine provisions apply
CAP subsidyPrecision spot-application (manufacturer-claimed ~95-96.6% herbicide reduction) supports CAP eco-scheme and integrated-pest-management / pesticide-reduction objectivesHerbicide-free mechanical vegetation control supports CAP eco-scheme and herbicide-reduction measures
