Aramis II vs Discovery Collector
Two robotic barn machines, one verified table. Every figure below is sourced and dated; vendor claims are labelled and kept apart from independent results.
Rail-guided all-in-one feeding robot from Tyrolean specialist Hetwin — weighs, cuts, mixes, doses and pushes feed around the clock from an overhead rail, with two horizontal mixing augers producing a homogeneous ration from batches as small as 50 kg. Aimed at medium herds of roughly 50–150 animals; sold and serviced in Switzerland via Harvestore.
Best for: Medium dairy and fattening barns (≈50–150 animals) wanting fully automatic group-specific fresh feeding without a mixer wagon — overhead rail keeps the feed alley clear.Lely's free-navigating manure robot for solid and semi-closed barn floors — instead of scraping manure ahead of itself it vacuums the slurry into an onboard tank, spraying water at the front for better intake and at the back to leave grip on the floor. Dumping, wireless charging and water refilling happen at one central station; the C2 generation handles barns of up to roughly 120 cows and routes are managed from a mobile app.
Best for: Dairy barns with solid or semi-closed floors (including cross alleys and sorting-gate passages) that want manure removed rather than pushed — cleaner floors and hooves without floor channels or cables.| Aramis II Verified 2026-07-16 | Discovery Collector Verified 2026-07-17 | |
