Element 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.
US solar-powered autonomous weeding robot from Aigen (Redmond, WA) that eliminates weeds mechanically with AI-guided ground strikes — no herbicide. The current gen2 platform (launched April 2025) widened its working crops to cotton, soy and sugar beet and runs a mesh-networked robotic "crew"; roughly 50 units were in field trials in North Dakota/Minnesota (Grand Farm) and California (Bowles Farming) through 2025; the 2024 and 2025 preorder rounds sold out in a day, and 2026 orderability is not independently confirmed.
Best for: US row-crop growers (cotton, soy, sugar beet) wanting to cut herbicide spend and pursue organic certification, and willing to run a multi-robot fleet rather than a single machine (Aigen's own example — ~5 robots to cover 160 acres / 65 ha in a season).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.| Element Verified 2026-07-18 | WEAI Verified 2026-07-17 | |

| Specifications | ||
| Power source | Solar-electric — onboard solar panel with battery backup (gen2 carries ~50% more solar capacity than gen1); no fuel used | Battery-electric — 2 batteries, ~7 kWh total, manually swapped; 8–12 h operation per day |
| Required tractor power | Not required (self-propelled) | Is the vehicle (three-point-hitch pickup by tractor for road transport) |
| Dimensions | Not disclosed | Bed widths 1.50–3.20 m, adjustable row spacing, 5–8 rows; tool/detection height electrically adjustable by 50 cm |
| Weight | Not disclosed | ~1,500–1,700 kg (vendor pages state 1,700 kg; Future Farming reported ~1,500 kg for the new platform) |
| Min farm size | Not disclosed | Not disclosed |
| Productivity | Illustrative fleet example from Aigen: ~5 robots to cover 160 acres (65 ha) in a season; a single robot's seasonal capacity is 20-40 acres depending on weed density | Keeps up to ~10 ha weed-free per robot per season |
| Max speed | Not disclosed | 1 km/h working speed |
| Sensors | Onboard stereo depth-vision cameras and onboard AI (gen2 has 4x the compute of gen1) for row-following and weed identification; mesh network lets robots coordinate as a "crew" | AI camera crop/weed detection · GPS-RTK navigation · safety bumpers, e-stops and cameras |
| Price & model | ||
| Price (EUR) | ≈€44,000 (indicative conversion) | Not disclosed |
| Native price | $50,000 | Not disclosed |
| Business model | Buy — $50,000 per robot (confirmed on TechXplore, quoting Aigen). A working deployment is typically several robots (Aigen's own illustrative example — ~5 robots per 160 acres / 65 ha). 2024/2025 preorder rounds sold out in a day; 2026 orderability not independently confirmed. | Sold and serviced via Homburg Holland (owner since 2024) in NL/BE; Ekobot AB channel in Sweden |
| Ongoing cost | Not disclosed — Aigen has not published ongoing service/software costs on its own materials. One third-party business-model summary cites an additional ~$20,000 per-fleet coordination/software fee, but that figure could not be confirmed on any primary or trade-press source, so it is not carried into this field. | Battery swapping/charging; finger-weeder wear parts; Homburg service, spares, training and warranty |
| Key outcome | ||
| Best verified result | Herbicide spend and organic-certification eligibility Zero-herbicide mechanical weeding in Grand Farm (ND) trial deployment — growers avoid herbicide spend and can pursue organic certification / premium pricing · independent | Onion yield +6% · vendor |
| EU context | ||
| CE marking | No CE marking evidence found — no EU sales or service presence identified (US-only — ND, MN, CA field trials/deployments) | EU-built series machine sold in NL/SE via an established dealer; CE marking not independently verified |
| Machinery Regulation | Not applicable — not placed on the EU market | Swedish-built, Dutch-owned series product; conformity maintained under the EU machinery regime |
| CAP subsidy | Not applicable — US-only company; no CAP relevance found | Herbicide-free weeding in high-value vegetables supports CAP eco-scheme and organic conversion goals |
