Vulcan 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.
US (Salinas, CA) tractor-drawn precision weeder using onboard cameras and computer vision to mechanically remove weeds in-row without herbicide. Original venture-backed maker FarmWise wound down independent operations on 1 April 2025 after raising $65M but failing to reach profitability; three days later, produce processor Taylor Farms (itself a prior FarmWise investor and long-time customer) acquired the FarmWise business outright to keep the Vulcan line running. As of mid-2026 Vulcan is still actively sold and field-supported — not discontinued — through an exclusive dealer partnership with RDO Equipment Co. across the Southwest US.
Best for: Large-scale US vegetable growers (multi-thousand-acre operations, the kind Taylor Farms and Barkley Farms run in Salinas/Yuma) who want to cut hand-weeding crew costs on lettuce, brassica, or tomato beds and can absorb a six-figure implement purchase plus annual service contract.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.| Vulcan Verified 2026-07-19 | RoamIO-HCW Verified 2026-07-19 | |

| Price & model | ||
| Price (EUR) | ≈€555,000 (+ ≈€39,000/yr service) — indicative conversion only; Vulcan is not sold or priced in the EU | Not disclosed |
| Native price | US$645,000 MSRP for the flagship three-bed 80 in Vulcan V380, plus a reported ≈US$45,000/yr service & support package — trade-press reported figures (Farm Progress, The Packer), not published on the FarmWise site; single-bed and 68 in/40 in models are priced lower but not disclosed | Not disclosed |
| Business model | Direct purchase (not RaaS), sold and field-supported exclusively through RDO Equipment Co. dealers across the Southwestern US since a September 2024 exclusive partnership; John Deere Financing and AgDirect financing offered; FarmWise also runs a "try before you buy" trial program (a free 1-week trial, or paid extended 100/250/500-acre trials with credits toward purchase) | 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. |

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 | Weeding cost, large multi-region vegetable operation ≈US$550,000 reduction in weeding costs in a single season (customer-reported figure, cited by trade press at the time Taylor Farms was a FarmWise customer, before its 2025 acquisition of the company) · vendor | Labour and fuel use for field tasks Up to 80% reduction (vendor claim; no independent measurement found) · vendor |
| EU context | ||
| CE marking | Not confirmed — no CE-marking evidence found; all documented deployments and dealer/service coverage are US-only (Southwest US) | 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 applicable found — no EU placement on the market; would fall under Regulation (EU) 2023/1230 autonomous-machine provisions if the Vulcan were ever sold into the EU | 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 | Not applicable — US-based product with no EU sales presence, outside EU CAP eco-schemes | Not applicable — US/Canada-market machine with no EU sales, so no CAP eco-scheme relevance. |
