The Roborock Saros 10R stands out as the thinnest model in Roborock's lineup at 7.98 cm, enabling it to navigate under low-clearance furniture and tight spaces effectively. It features advanced navigation through its StarSight Autonomous System 2.0, which uses LiDAR and 3D Time-of-Flight sensors for precise mapping and obstacle detection. The vacuum's dual spinning mops automatically adjust based on floor type, and its 10-in-1 docking station offers self-cleaning capabilities with hot water washing and heated air drying. While it excels in navigation and accessibility, its 2.5-hour charging time and need for regular dock maintenance are noted drawbacks. This model is ideal for users seeking a compact yet capable robot vacuum for homes with low-clearance areas and those who value smart mapping and self-cleaning features.

Strengths
  • Ultra-slim design at 7.98 cm tall, allowing access under low-clearance furniture
  • StarSight Autonomous System 2.0 with LiDAR and 3D Time-of-Flight navigation for precise mapping
  • Dual spinning mops automatically lift when approaching soft surfaces like carpets
Watch-outs
  • High price point
  • Limited Wi-Fi compatibility
Roborock Saros 20
Ranked #4 in Best Robot Vacuums
Roborock Saros 20
8 sources$1,599.99as of Aug 23

The Roborock Saros 20 delivers strong performance in both vacuuming and mopping, with powerful suction and effective cleaning technology. It features a self-cleaning dock and quiet operation, but comes at a steep price point and has a bulky base station that's difficult to relocate. The device is well-suited for users seeking premium cleaning capabilities but may be overkill for those with simpler needs or budget constraints.

Strengths
  • Powerful suction with 36,000 pascals of official suction rating
  • Effective mopping with dual mop pad design spinning at 200 RPM
  • Self-cleaning dock with boiling hot water mopping and automatic drying
Watch-outs
  • Heavy base station that is difficult to move between floors
  • High price point

How they stack up

Roborock Saros 10R

The Roborock Saros 10R's ultra-slim profile and StarSight 2.0 navigation system set it apart from the Roborock Saros 20, which is bulkier and lacks the same level of smart mapping. However, it doesn't match the Saros 20's suction power or the Eufy Omni C28's anti-tangle design.

Roborock Saros 20

The Roborock Saros 20 stands out with its powerful 36,000 pascals suction and self-cleaning dock with boiling hot water mopping, which the Dreame D30 Ultra and Shark PowerDetect UV Reveal lack. However, unlike the Roborock Saros 10R, it doesn't offer the ultra-slim design or advanced 3D navigation, and its heavy base station is a drawback compared to more portable models like the Roomba J7.
