Classic Waring - inside and out. This is the blender that the professionals use. You'll recognize our trademark 40 oz. cloverleaf carafe. It was designed to create a vortex action for faster, thorough blending, and it works! The commercial grade 2-speed 390-watt motor is more power than most home kitchens need, but it makes even heavy tasks like ice-crushing effortless. With a self-cleaning blade assembly, this blender cleans up after itself!
