Choosing a Robot Vacuum: More Than Just Suction Power

Fast Summary

• Robot vacuums are increasingly marketed with high suction power, measured in pascals (Pa). models like the Dreame x50, Roborock saros 10, and Ecovacs x8 boast power ranging from 18,000 to 22,000 Pa.
• Engineers admit that suction levels often aim to meet consumer demand rather than practical utility. In tests, designs like rollers and sweepers significantly influence cleaning efficacy.
• Issues include debris clogging the rollers or vacuum pipes regardless of high suction power. Design aspects such as roller effectiveness and frame height matter more for usability.
• Navigation features powered by AI and slimmer vacuum bodies are evolving to better access spaces under furniture while mitigating debris avoidance errors.
• Dock designs, where robots auto-empty debris into a vacuum bag for autonomy purposes, need streamlined pipe design to prevent clogs.
• Performance varies based on specific home requirements (e.g., large vs. small spaces or types of obstacles), suggesting no universally “best” robot vacuum.
