Aramis II vs Barn-E PRO
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.Manure robot for solid barn floors from Dutch manure-handling specialist JOZ — a low 68 cm collector that carries the manure it gathers (350 or 500 litres depending on push width) instead of pushing a growing heap, navigating unlimited programmable routes via floor transponders. Connected to the JOZ Management System for 24/7 remote monitoring with SMS obstacle alerts; JOZ pitches the PRO generation as its most powerful robot for intensive conditions, coping with straw bedding up to 6 cm.
Best for: Dairy barns with solid floors and demanding conditions (straw bedding, long routes) wanting collected manure and precise transponder-guided routes with remote monitoring.| Aramis II Verified 2026-07-16 | Barn-E PRO Verified 2026-07-17 | |
