AX-1 vs RoamIO-HCW
Two weeding machines, one verified table. Every figure below is sourced and dated; vendor claims are labelled and kept apart from independent results.
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.Canadian (Oshawa, Ontario) multipurpose autonomous field robot — Korechi's largest and first wheeled RoamIO model, built to seed, weed, cultivate, mow, soil-sample, data-log and transport across an adjustable-width chassis. Battery-electric with cm-level RTK GNSS navigation and dual AI-camera obstacle detection; Korechi's own product page states it is "now taking orders." Pricing is not published by Korechi itself — an independent buyer's guide lists a starting price of roughly $80,000 (final price varies by configuration) — and the company currently serves only the US and Canadian markets.
Best for: Vegetable and horticultural growers in the US or Canada wanting one multipurpose autonomous tool-carrier (seeding, weeding, cultivating, mowing, transport, data-logging) from a small Ontario-based robotics maker that is actively taking orders.| AX-1 Verified 2026-07-18 | RoamIO-HCW Verified 2026-07-19 | |

| Price (EUR) | ≈€130,000 | Not disclosed |
| Native price | ≈€130,000 (third-party: Future Farming robot database — Kilter quotes individually) | Not disclosed |
| Business model | Buy — 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, direct from Korechi Innovations (Oshawa, ON) — the RoamIO-HCW product page states "WE ARE NOW TAKING ORDERS"; contact required for a configuration-specific quote/demo, no published dealer network. Korechi publishes no price; Future Farming's buyer's guide listed a US$80,000 starting figure at a Nov-2023 exchange rate — a dated third-party data point, not a verified current price. |
| Ongoing cost | Herbicide/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. | Not disclosed in detail. Optional paid add-ons found: extra battery packs, a petrol/diesel generator for range extension, an auxiliary data-logging computer, LED floodlights, and structural mounts for extra sensors/implements. |
| Key outcome | ||
| Best verified result | Spray 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 | Labour and fuel use for field tasks Up to 80% reduction (vendor claim; no independent measurement found) · vendor |
| EU context | ||
| CE marking | No 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) | No CE marking found — Korechi states on its own homepage that it "currently serve[s] the US and Canadian markets"; no EU sales or compliance evidence found. |
| Machinery Regulation | Not 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 assessed | Not placed on the EU market; would need to meet the autonomous-machinery provisions of Regulation (EU) 2023/1230 if it ever entered the EU. |
| CAP subsidy | Precision spot-application (manufacturer-claimed ~95-96.6% herbicide reduction) supports CAP eco-scheme and integrated-pest-management / pesticide-reduction objectives | Not applicable — US/Canada-market machine with no EU sales, so no CAP eco-scheme relevance. |
