64-ounces

It is made with stainless steel blades designed to deliver the same quality results, from first blend to last and are resistant to dulling or bending.

The blades reach speeds fast enough to create friction heat, bringing cold ingredients to steaming hot in about six minutes.

With a drop of dish soap and warm water, your Vitamix machine can clean itself in 30 to 60 seconds.

Just blend warm water and a drop of dish soap at your machine's highest speed, and watch it self-clean in 60 seconds—no disassembly required.

Pair with any self-detect containers: add a range of compatible container sizes, building a customized blending system designed to fit your needs.

A built-in digital timer removes the guesswork with recipes you process manually, helping you achieve the perfect texture every time.

A radial cooling fan and thermal protection system make it a heavy-duty appliance.

Blender is 40% quieter than the Vitamix with 7 dB of sound reduction. The 1,440-watt motor harnesses 2.2 horsepower.

The size and shape of the self-cleaning 64-ounce container are ideal for blending medium to large batches.

You can simulate a Pulse mode by switching the blender on and off while set to the 'High' speed setting, which makes bar-quality crushed ice in about two minutes. This pulse feature makes chunky salsas, thick vegetable soups, and more.

The powerful motor and durable construction make this classic blender one of the best heavy-duty blenders on the market. It is a commercial-grade blender.

The base is strongly and solidly built in the USA with the strongest of materials which makes it durable.

Easily adjust speed to achieve a variety of textures. The dial can be rotated at any point during the blend, so you’re in complete control.

Every Vitamix blender comes with a tamper designed to help process thick, stubborn blends—so you don’t have to stop the machine to scrape the sides.

Available- Blend frozen fruit, heavy powder, and all the greens—the powerful motors transform tough ingredients into smooth blends, year after year.

Hardened stainless steel blades can crush ice like it is no challenge.

It's incredibly durable, versatile, and easy to clean – all qualities Vitamix owners value in a blending container. And, since it comes with a clear, BPA-free lid, you can monitor and adjust blends without stopping the machine.
