Quick verdict
Based on official specifications, choose the Saros 20 to investigate Roborock's newer 36,000 Pa motor claim and AdaptiLift Chassis 3.0. Choose the Saros 10R when its 10-in-1 Multifunctional Dock 4.0, 4 cm maximum double-layer threshold claim and established feature set already meet the brief. Neither conclusion is based on hands-on testing.
Who should choose the Saros 10R
It is the more straightforward fit for shoppers focused on a slim 79.8 mm StarSight robot, an up-to-4 cm maximum double-layer threshold claim, automatic mop handling and a dock designed to reduce routine intervention.
Who should choose the Saros 20
It is the model to investigate for homes with specifically shaped double-layer thresholds or for shoppers prioritizing the newest published suction figure. Roborock's 8.8 cm combined claim applies only to its stated two-layer geometry.
Navigation and clearance
Both product pages list StarSight Autonomous System 2.0 and a robot body height of 79.8 mm. The Saros 20 page additionally describes low-clearance navigation down to 7.95 cm through limited passive compression, while warning that scraping and environmental variation may occur.
Cleaning system tradeoffs
The Saros 20 page highlights a 36,000 Pa digital motor, dual anti-tangle design and dual spinning mops. The Saros 10R page emphasizes FlexiArm components, liftable cleaning hardware, automatic mop removal and the Multifunctional Dock 4.0. Published features do not establish which cleans better in an uncontrolled home.
Dock and installation
Both docks require meaningful floor space and access for maintenance. Verify the exact regional configuration because refill-and-drain variants have additional plumbing, clearance and installation requirements.
Bottom line
The Saros 20 leads on newer headline claims; the Saros 10R remains a credible fit when its published system matches the home. Measure first, compare current regional packages second, and avoid paying for capabilities your floor plan cannot use.
