How does the Xiaomi X20 Pro's suction compare to the Roborock S5?

The Xiaomi X20 Pro’s 4,000Pa suction significantly outperforms the [Roborock S](https://www.amazon.com/s?k=Roborock+S&tag=wehavethat-20)5's 2,000–2,500Pa, pulling up heavier crumbs and pet hair that the Roborock needs multiple passes to catch. In a real-world test on a medium-pile rug, the Xiaomi’s bin was noticeably fuller after one cycle. The Roborock S5 was great in its day, but the X20 Pro is the clear current winner.
