DeLaval · Sweden

DeLaval's robotic feed pusher-and-remixer — unlike plain pushers, a twin-spiralled rotating auger remixes the ration while repositioning it at the feed fence, keeping roughage strands intact so refused compacted feed stays appetising. Adaptive Drive adjusts speed and track to feed type and quantity; runs around the clock, up to 10 trips a day. Direct competitor to the Lely Juno.

Best for: Robotic-milking or free-stall dairy herds that want feed pushed AND remixed 24/7 — especially where compressed, sorted-through TMR is depressing intake at the fence.
GEA Farm Technologies · Germany

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.
