This blender has several programs and modes. There’s a self-clean program, which is convenient, and a timer that operates more like a stopwatch by counting how long you’ve been blending. You have to watch the blender and stop it at the desired time. You can access all of the presets (Smoothies, Hot Soups, Frozen Desserts, Spreads, Dry Chopping, Nut Butters, Cold Skim Milk Foam, Dressings, Spice Grinding, Baby Food, Marinades, Frozen Cocktails, Nut Milks, Thick Dips, Batter, and Acai Bowls) via the Vitamix Perfect Blend companion app, which connects to the blender using Bluetooth. Unlike the timer, these programs run for a set amount of time and stop automatically.
