Roborock Saros 20 is one of the best robot vacuums, refined

The Roborock Saros 20 impressed in home testing with stronger suction, better threshold crossing, and improved mopping performance.

Its AdaptiLift chassis, Starsight navigation, and redesigned RockDock helped it handle obstacles and docking more smoothly.

The vacuum refines an already top-tier robot cleaner, but it still struggles a bit in tight spaces.

The review highlights how incremental hardware and navigation upgrades can solve real-world robot vacuum pain points.
