SRone 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.
GEA's battery-powered manure scraper robot for slatted floors — a flat, quiet 400 kg unit that pushes slurry through the slats with up to 100 kg of pushing force, turns fully within 2 m and slips under gates. The lateral-guidance SRone cleans up to 8,000 m² of slatted floor per day; the programmable SRone+ extends that to 12,000 m² with custom route plans. Runs up to 19.5 h per day on a 4.5 h quick charge.
Best for: Dairy barns with slatted floors — from simple straight walkways (SRone) to larger barns with complex, personalised routes (SRone+) — wanting continuous slat cleaning without floor cables.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.| SRone Verified 2026-07-17 | Discovery Collector Verified 2026-07-17 | |
