RoamIO-HCW vs Inter-Plant Weeder SA-AI
Two weeding machines, one verified table. Every figure below is sourced and dated; vendor claims are labelled and kept apart from independent results.
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.Tractor-mounted, chemical-free in-row weeder from SPAPPERI N.T. S.R.L. (Città di Castello, Italy; est. 1964). A hydraulic PTO-driven frame (1-4 rows) carries per-row "BOX AI" units — a 3D camera plus AI vision developed with Czech partner Ullmanna — that detect each plant's root and drive independent vertical rotary tillers or fixed knives to weed within the row. Spapperi's own brochure calls it both "SA-IA" and "SA-AI"; the product is marketed via that brochure and lead-gen listings rather than a dedicated page on Spapperi's main site as of this check.
Best for: Commercial vegetable and root-crop growers (Spapperi's own examples include lettuce, cabbage, pumpkin and sugar beet) who already run an appropriately-sized tractor with rear hydraulics and want mechanical in-row weed control without GPS guidance or chemical herbicides.| RoamIO-HCW Verified 2026-07-19 | Inter-Plant Weeder SA-AI Verified 2026-07-19 | |

| Required tractor power | Not required (self-propelled); 13.4 hp (10 kW) brushless DC motors, peak 22.2 hp (16.6 kW) | Not disclosed — Spapperi specifies PTO-driven hydraulic transmission but publishes no minimum tractor horsepower figure for the SA-AI |
| Dimensions | 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 | Not disclosed — modular frame (1-4 rows, single or double planting-row spacing); overall width/length vary by configuration |
| Weight | 1,300 lb (590 kg) | Not disclosed |
| Min farm size | Not disclosed | Not disclosed — no hectare threshold published; the multi-row tractor-mounted design targets commercial vegetable/root-crop operations |
| Productivity | Not disclosed | 4,500-8,500 plants/hour per row, depending on in-plant spacing |
| Max speed | 4 mph (6.5 kph) | Not disclosed |
| Sensors | 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 | 3D camera plus integrated lighting per weeding element ("BOX AI", AI vision by Ullmanna) for day/night plant-root detection; anti-collision sensors on each element arm; central "Power Box" CPU with GPS and internet connectivity |
| Price & model | ||
| Price (EUR) | Not disclosed | Not disclosed |
| Native price | Not disclosed | Not disclosed |
| Business model | 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. | Buy — tractor-mounted implement sold direct from Spapperi NT S.r.l. (Città di Castello, Italy); AI vision developed with Czech partner Ullmanna, integrated as Spapperi's "BOX AI - Ullmanna System" |
| Ongoing cost | 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. | Interchangeable rotary-tiller/knife wear parts; hydraulic oil and PTO-pump upkeep; AI crop models update automatically over the internet (Spapperi states a new crop can be added in about 6 hours) |
| Key outcome | ||
| Best verified result | Labour and fuel use for field tasks Up to 80% reduction (vendor claim; no independent measurement found) · vendor | In-row weeding labour Vendor testimonial states each row unit replaces about 10 manual workers · vendor |
| EU context | ||
| CE marking | 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. | Not disclosed — no CE-marking statement found for the SA-AI on Spapperi's site, its brochure, or the dealer-contact page |
| Machinery Regulation | 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. | Not disclosed — would fall under Regulation (EU) 2023/1230 as a mounted implement with AI-driven functions if placed on the EU market; no explicit compliance statement found |
| CAP subsidy | Not applicable — US/Canada-market machine with no EU sales, so no CAP eco-scheme relevance. | Not disclosed — mechanical/AI in-row weeding removes herbicide use, which is relevant to CAP eco-schemes rewarding reduced chemical inputs, but Spapperi does not tie the SA-AI to CAP explicitly |
