Our Verdict

Ninja Blender Duo with Auto-iQ BL642

Ninja Professional Plus Kitchen System with Auto-iQ

The Ninja Blender Duo with Auto-iQ BL642 and the Ninja Professional Plus Kitchen System with Auto-iQ perform very similarly but come with different jars. The Duo comes with a 72-ounce main jar with two or three personal jars, while the Kitchen System comes with a similar main jar, two personal jars, and a separate bowl and blade for food processing.
