SRone vs Astronaut Max
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.Centralised milking architecture for large herds (announced August 2025) — up to 18 Astronaut robots share one control room for vacuum, cleaning, cooling and long-distance milk transport.
Best for: Dairy farms of 500–1,100 cows wanting robot milking without one full utility set per box.| SRone Verified 2026-07-17 | Astronaut Max Verified 2026-07-16 | |
