All Bosch hand blenders have a sturdy and durable stainless steel immersion blender foot. These immersion blenders have many speed settings, so you can accurately match the speed to the preparation. Bosch carries two series of immersion blenders, the ErgoMixx and the MaxoMixx. The difference is in the immersion blender head. Both lines have a cross blade with 4 blades. Two of the four blades are slightly larger on the MaxoMixx. In addition, the shape of the head is slightly different, for a better mixing result.
