5 Differences Between the Xiaomi S40 and H40 Robot Vacuums

Navigation The S40 uses LiDAR for smarter routing and room mapping, while the H40 relies on gyroscope-based navigation that is less precise.

Suction power The H40 has stronger suction, making it better at picking up debris on the first pass, especially on carpets.

Cleaning efficiency The S40 cleans more methodically, reducing missed spots and re-cleaning, while the H40 may need extra passes in complex layouts.

Battery life Both have similar runtimes, but the S40’s efficient navigation can extend effective cleaning time per charge.

Price The H40 is typically cheaper, but the S40’s navigation upgrade justifies the higher cost for larger or multi-room homes.
