CLAWS 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.
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.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.| CLAWS Verified 2026-07-17 | RoamIO-HCW 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 | Battery-electric — 20 kWh "safe lithium chemistry" pack rated 10+ years of life; optional extra battery packs or a petrol/diesel generator for extended range |
| Required tractor power | Is the vehicle (lightweight autonomous platform, no tractor needed) | Not required (self-propelled); 13.4 hp (10 kW) brushless DC motors, peak 22.2 hp (16.6 kW) |
| Dimensions | ~2 m working width; other dimensions not disclosed | 74" x 70.5"–83.5" x 64" (1.87 m x 1.79–2.12 m x 1.62 m, L x W x H); width adjustable 47.5"–75.5" (1.2–1.91 m) in 2" increments |
| Weight | Not disclosed | 1,300 lb (590 kg) |
| Min farm size | Not disclosed | Not disclosed |
| Productivity | ~1.5 ha per 8 h day demonstrated; ~4 ha/day targeted for the commercial fully autonomous machine, weed burden depending | Not disclosed |
| Max speed | Not disclosed | 4 mph (6.5 kph) |
| Sensors | 8 onboard cameras (stereo imaging) · AI per-plant identification · satellite navigation · FIELD digital-twin scouting software | Multi-constellation multi-band GNSS RTK with dual antenna for cm-level positioning; dual AI-powered cameras for obstacle/collision detection; physical and remote e-stop |
| Price & model | ||
| Price (EUR) | Not disclosed | Not disclosed |
| Native price | Not disclosed | Not disclosed |
| Business model | Weeding as a service, charged per hectare — positioned at parity with tractor-based weeding and below manual weeding cost | 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 | Service-model pricing per hectare; no published machine list price | 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 | Herbicide use Chemical-free concentrated-light weeding, zero-till; controls ALS-resistant weeds (Niab-tested, vendor-reported) · vendor | Labour and fuel use for field tasks Up to 80% reduction (vendor claim; no independent measurement found) · vendor |
| EU context | ||
| CE marking | Not verified — pre-series Beta Pioneer machine, UK-focused rollout | 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 | Post-Brexit UK machine; EU conformity route not published | 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 | Chemical-free zero-till weeding aligns with CAP eco-scheme goals, but no EU sales channel is evidenced yet | Not applicable — US/Canada-market machine with no EU sales, so no CAP eco-scheme relevance. |
