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.
Lely · Netherlands

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.
