JOZ · Netherlands

Manure robot for solid barn floors from Dutch manure-handling specialist JOZ — a low 68 cm collector that carries the manure it gathers (350 or 500 litres depending on push width) instead of pushing a growing heap, navigating unlimited programmable routes via floor transponders. Connected to the JOZ Management System for 24/7 remote monitoring with SMS obstacle alerts; JOZ pitches the PRO generation as its most powerful robot for intensive conditions, coping with straw bedding up to 6 cm.

Best for: Dairy barns with solid floors and demanding conditions (straw bedding, long routes) wanting collected manure and precise transponder-guided routes with remote monitoring.
Wasserbauer Fütterungssysteme · Austria

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.
