Barn-E PRO 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.
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.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.| Barn-E PRO Verified 2026-07-17 | Discovery Collector Verified 2026-07-17 | |
