Discovery Collector vs Butler Gold Pro

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.

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.
