Open questions

The claim of 20,000 Pa suction power.

Limited evidence · What we still need: Independent lab testing to verify the stated suction power would provide stronger evidence.

Long-term durability and reliability of the robot and docking station components.

Limited evidence · What we still need: Longitudinal studies or user feedback aggregated over several months could assess long-term performance.

Performance comparison against a wider range of direct competitors on key tasks like carpet cleaning and obstacle avoidance.

Limited evidence · What we still need: A comparative review with 2-3 top competing models would provide a more complete market context.
