The ACTIVEBlade technology incorporates a flexible shaft that moves the blade up and down. The result is a more active cutting surface to work with which results in finer blending. This motion gives you flavorful, smooth results with no unwanted pieces while requiring less effort than traditional blending shafts. The POWERBell Plus features an extra milling blade to blend large pieces of food more easily. Advanced SPLASHcontrol technology prevents splashing and delivers the best blending results to keep you and your kitchen clean. Additionally, the MQ9 provides less suction for effortless handling and perfect control. With Braun's SmartSpeed technology, you can intuitively adjust blending power without stopping. Push gently for coarse results and apply a little more pressure for more power and finer results. Plus, the SmoothStart feature prevents jolting on startup.
