5 Things to Know About the Xiaomi S40’s 4000Pa Suction
- The S40 has 4000Pa of suction, while the H40 has 3000Pa. That extra 1000Pa makes a real difference on carpets.
- On carpets, the S40 pulls out embedded dust and pet hair that the H40 leaves behind. It is noticeably better for deep cleaning.
- On hard floors, both models perform fine. The S40’s extra suction is not needed there.
- The S40 only justifies its higher price if you have rugs or carpeted rooms. If your home is all hard floors, save money with the H40.
- Suction is the main differentiator between these two models. Do not pay for the S40 unless you need that carpet performance.
