CLAWS vs Vulcan
Two weeding machines, one verified table. Every figure below is sourced and dated; vendor claims are labelled and kept apart from independent results.
Concentrated Light Autonomous Weeding and Scouting (CLAWS) robot from UK startup Earth Rover — its patented Lightweeder destroys the meristem of individual weeds with a short pulse of concentrated (non-laser) light, chemical-free and zero-till, on a 100% battery + solar platform with 8 onboard cameras that double as a crop-scouting system. Order book opened Q3 2025; deliveries scheduled from Q1 2026 under a weeding-as-a-service model.
Best for: Organic and chemical-free vegetable and row-crop growers (UK first) who want herbicide-free, zero-till weed control plus per-plant scouting data, paid per hectare rather than as capex.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.| CLAWS Verified 2026-07-17 | Vulcan Verified 2026-07-19 | |

| Specifications | ||
| Power source | 100% electric — battery + solar; battery alone runs roughly half a day, solar panels extend to a full day | Tractor-drawn, PTO-driven implement (not self-propelled) |
| Required tractor power | Is the vehicle (lightweight autonomous platform, no tractor needed) | Not disclosed as an HP figure; compatible with standard Category II 3-point-hitch tractors, including John Deere 5-Series (V440 model) and 6-Series tractors |
| Dimensions | ~2 m working width; other dimensions not disclosed | Single-bed working width 76-84 in (1.93-2.13 m); three-bed (V380/T380) working width reported as roughly 20-21 ft (6-6.4 m); four-bed V440 in 40 in bed spacing |
| Weight | Not disclosed | Not disclosed precisely by FarmWise; independent coverage puts the single-bed unit at roughly 3,000 lb (1,360 kg) and the three-bed unit at roughly 7,000 lb (3,175 kg) |
| Min farm size | Not disclosed | Not disclosed; documented deployments are on large multi-thousand-acre vegetable operations (e.g. a 10,000-acre Yuma, AZ/Salinas, CA grower), not smallholdings |
| Productivity | ~1.5 ha per 8 h day demonstrated; ~4 ha/day targeted for the commercial fully autonomous machine, weed burden depending | 25+ acres/day, 3-4+ acres/hour per manufacturer spec sheet; a two-unit Taylor Farms fleet reported covering up to 100 acres in a single week |
| Max speed | Not disclosed | 1.5-4 mph |
| Sensors | 8 onboard cameras (stereo imaging) · AI per-plant identification · satellite navigation · FIELD digital-twin scouting software | Multiple high-resolution, camera-equipped row units (18 cameras reported on the three-bed unit) plus custom LED lighting for all-lighting and night operation; onboard computer vision and deep-learning models for weed/crop differentiation |
| Price & model | ||
| Price (EUR) | Not disclosed | ≈€555,000 (+ ≈€39,000/yr service) — indicative conversion only; Vulcan is not sold or priced in the EU |
| Native price | Not disclosed | 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 |
| Business model | Weeding as a service, charged per hectare — positioned at parity with tractor-based weeding and below manual weeding cost | 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) |
| Ongoing cost | Service-model pricing per hectare; no published machine list price | Reported ≈US$45,000/yr service & support package per unit (trade-press figure); consumable weeding-blade wear parts; software/AI model updates delivered via the onboard edge-learning system |
| Key outcome | ||
| Best verified result | Herbicide use Chemical-free concentrated-light weeding, zero-till; controls ALS-resistant weeds (Niab-tested, vendor-reported) · vendor | 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 |
| EU context | ||
| CE marking | Not verified — pre-series Beta Pioneer machine, UK-focused rollout | Not confirmed — no CE-marking evidence found; all documented deployments and dealer/service coverage are US-only (Southwest US) |
| Machinery Regulation | Post-Brexit UK machine; EU conformity route not published | 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 |
| CAP subsidy | Chemical-free zero-till weeding aligns with CAP eco-scheme goals, but no EU sales channel is evidenced yet | Not applicable — US-based product with no EU sales presence, outside EU CAP eco-schemes |
