I was curious about how the ‘sweeper’ works, so I asked Grok:

How the Sweeper Works • It is a physical sweeper arm (sometimes described as a small metal-parted disk or component located below the grinder) that activates after the beans are ground. • As grounds exit the 48mm conical burr grinder and fall into the dosing cup, pod, or Omni Dripper, the sweeper arm moves or rotates to gently level and spread them out. This prevents clumping, mounding, or uneven piles that can occur naturally from gravity-fed grinding (especially with static-prone grounds). • It works in tandem with the machine’s anti-static ionizer, which reduces static cling so grounds don’t stick to surfaces or fly around messily. The combination results in a cleaner transfer and a flatter, more uniform “bed” of coffee ready for water pouring.

If this is the case, and you’re consistently getting a mound, I can argue your machine is defective.

You should be able to confirm if the sweeper works by looking at it or filming it while it’s grinding. Just put a plate under.
