How does the Xiaomi S40 Pro's suction compare to the H40 for carpet cleaning?

The S40 Pro’s 4000Pa suction is a real upgrade over the H40’s 2500Pa — it pulls embedded dirt and pet hair out of medium-pile carpets in a way the H40 can’t match. If your home is mostly hard floors, the H40’s suction is adequate; if you have area rugs or carpeted rooms, the S40 Pro is the one that actually deep-cleans them.
