CLAWS vs WEAI
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.Swedish battery-electric weeding robot purpose-built for onion beds (and extending to carrots and beetroot) — AI vision plus GPS-RTK guide finger weeders that pull up to five weeds per second per unit across 5–8 rows on beds 1.50–3.20 m wide. The ~1,500–1,700 kg platform runs 8–12 h per day on ~7 kWh of swappable batteries at 1 km/h and can be lifted on a tractor three-point hitch for road transport. Dutch dealer Homburg Holland became importer (NL/BE), then acquired Ekobot outright in 2024, planning 20 machines for the Netherlands and Sweden in 2025.
Best for: Onion growers (and increasingly carrot/red-beet growers) in the Netherlands, Belgium and Sweden with ~10 ha of beds per robot who want season-long autonomous mechanical in-row weed control with established dealer support via Homburg.| CLAWS Verified 2026-07-17 | WEAI Verified 2026-07-17 | |

| 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 | Sold and serviced via Homburg Holland (owner since 2024) in NL/BE; Ekobot AB channel in Sweden |
| Ongoing cost | Service-model pricing per hectare; no published machine list price | Battery swapping/charging; finger-weeder wear parts; Homburg service, spares, training and warranty |
| Key outcome | ||
| Best verified result | Herbicide use Chemical-free concentrated-light weeding, zero-till; controls ALS-resistant weeds (Niab-tested, vendor-reported) · vendor | Onion yield +6% · vendor |
| EU context | ||
| CE marking | Not verified — pre-series Beta Pioneer machine, UK-focused rollout | EU-built series machine sold in NL/SE via an established dealer; CE marking not independently verified |
| Machinery Regulation | Post-Brexit UK machine; EU conformity route not published | Swedish-built, Dutch-owned series product; conformity maintained under the EU machinery regime |
| CAP subsidy | Chemical-free zero-till weeding aligns with CAP eco-scheme goals, but no EU sales channel is evidenced yet | Herbicide-free weeding in high-value vegetables supports CAP eco-scheme and organic conversion goals |
