SELF-DETECT technology is part of all Ascent™ Series blenders and their containers. This means your machine knows which container size you are using, and automatically adjusts program settings and maximum blend times accordingly.
In addition to optimizing your blends, SELF-DETECT® containers also offer an added level of safety. On models with program settings, certain programs like hot soup are disabled for the (8- and 20-ounce) Blending Bowls and Blending Cups. On models without program settings, the blender will shut off after 1:15 of blending in the 8- and 20-ounce containers, because they don’t have vented lids like the full-size containers do. Vitamix Ascent Series blenders will not begin blending if the container isn’t sitting properly on the base, or if the detachable blade base for the smaller containers isn’t properly attached.
