Increased efficiency – can milk twice as many animals in the same time compared to a single barrel machine. Typical productivity might be ~20–30 cows per hour (two at once), depending on model and setup.
Labor savings – reduces manual work and allows a single operator to manage more animals.
Better hygiene and milk quality – sealed systems and stainless steel parts reduce contamination risks.
Animal comfort – controlled vacuum and pulsation reduce stress on udders compared to poorly done hand milking.
