Which robot vacuum has better deep-cleaning performance on shag carpets?

The Ecovacs T90 Pro Omni has about a 10% real-world advantage on deep shag carpets and stubborn pet hair mats, thanks to its 11,000 Pa suction versus the [Roborock S](https://www.amazon.com/s?k=Roborock+S&tag=wehavethat-20)aros 20’s 10,000 Pa. On hard floors and low-pile carpet, they’re nearly identical, but the Ecovacs wins the deep-clean contest by a nose.
