Aigen · United States

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).
Naïo Technologies · France

Compact electric weeding robot for vegetable beds and small market gardens.

Best for: Diversified market gardens under 5 ha wanting to cut hand-weeding without herbicide.

Business modelBuy — $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.Buy outright · lease from €640/mo
Ongoing costNot 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.€900/yr service contract + consumables
