Like the Ascent A3300, the A3500 also replaces the the switch interface of the A2300 and A2500 with more modern touch style panel, which makes clean up much easier with a simple wipe down. What sets the A3500 apart from the A3300 is the 5 on-panel preset programs (Smoothies, Hot Soups, Dips & Spreads, Frozen Desserts, Self-Cleaning). The A3500 still has the 1-10 speed dial, along with SELF-DETECT® Technology, and a Digital Timer. Pair it with the Vitamix app and unlock the full potential of the blender with 17 programs and over 500 recipes.
