Our System One vacuum source will milk one or two goats at a time. It is lightweight, durable, and draws only 7.2 amps -- small enough for household wiring. It has a powerful 1/2 hp motor, a maintenance-free oil-less pump, and on-off switch, so you can keep it plugged in. It comes with wheels and handle and is in stock and ready to ship. Our System One vacuum system can be used with either our one or two goat bucket assemblies. Shipping charges range from $49.55 to $75.85, depending on your shipping zone. Vacuum source comes with a copy of our booklet "Your System One Milking Machine," so you don't have to order one.
