SRone vs Butler Gold 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.
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.Free-driving feed pusher and concentrate dispenser from Austrian feeding specialist Wasserbauer — a 700 kg, 24 V robot that navigates by 5 mm floor magnets set roughly every 2 m, makes up to 99 passes per day and, unlike a plain pusher, uses a special auger to throw feed loosely back to the trough without pressing it. Its 120-litre container (or 2 × 60 l for two components) doses concentrate, minerals or liquids onto the base feed along the way; the drive-over charging station manages batteries automatically.
Best for: Dairy barns wanting more than a pushing drum: fresh, loosened feed plus in-pass concentrate/mineral dosing from one robot, with typical energy use under 4 kWh/day for a 100-cow barn at 14 passes.| SRone Verified 2026-07-17 | Butler Gold Pro Verified 2026-07-17 | |
