Blades-free spin detection. Why my millo is slowing down?

The blades-free spin detection feature lowers the blender speed to around 15% of full capacity when its sensor detects that the blades are spinning with no resistance. This usually happens when: 

• Blending larger chunks of food as they tend to get stuck on the upper part of the cup.
• Blending sticky food items (like making peanut butter) or ice cubes as an air bubble usually appears. 
• Blending empty which is not recommended.

After 5 seconds of resistance free-spinning, blending speed lowers to around 15% capacity and ensures power-saving, and manual speed control appears.

If large chunks are stuck in the blender or there is an air gap - stop the blending cycle, remove the blending cup from the base and shake the cup. If the ingredients still get stuck while blending, stop the blending cycle, remove the blending cup from the base, open it, and scrape the mixture from the sides of the cup. Alternatively, make sure that there are no ingredients stuck in the blending cup, remove the tool used for scraping,  close the blending lid, and start the blending process again.

For blending sticky food items (powder with liquid, peanut butter etc.) use lower speed throughout the whole blending cycle or until the consistency is smooth enough and no air bubble can form.
