Xiaomi X20 Pro vs Roborock S5: X20 Pro wins on suction power by a clear margin

The Xiaomi X20 Pro’s 4,000Pa suction easily outperforms the Roborock S5’s 2,000–2,500Pa, pulling up heavier crumbs and pet hair in one pass that the Roborock needs multiple cycles to catch. On a medium-pile rug, the X20 Pro’s bin was noticeably fuller after one cycle. The Roborock S5 was great in its day, but the X20 Pro is the current winner.
