We didn't test this.We read 7 expert reviews (7 hands-on) and 283 comments from owners, then scored them with our published formula.
Experts say 83.
Owners say 62.
All 7 expert reviewers tested the Saros 20 hands-on and score it 83, praising its 36,000Pa suction, carpet cleaning and a lifting chassis that clears thresholds quoted at 57mm to 8.8cm. Owners are cooler at 62: 35% of 283 owner comments praise suction, but 12% complain about navigation and 8% say it gets stuck. Every expert flags the price, and two call it only an incremental step over the Saros 10/10R. Long-term reliability evidence is thin: 9% of comments mention failures and 5% say a unit broke or died, but expert testing was short-term and only 6 reviewers published scores.

Paraphrased · tap to read the originalA premium robot vacuum that excels at carpet cleaning, hair-tangle resistance, climbing and docking automation, but whose flat sonic mop and pet-hair pickup underperform for the price, so the standard Saros 20 is better for mopping.
trustedreviews.comhands-on ↗5/5A refined, very powerful flagship that excels at suction, mopping and handling mixed flooring and obstacles, and the writer calls it the best robot vacuum tested, though it is pricey and not worth upgrading from the Saros 10 or 10R.
businessinsider.comhands-on · implied ↗~6/10A well-built, thin, quiet and nimble flagship that handles routine upkeep and tricky thresholds well, but it is only an incremental step over the Saros 10R, struggles with big messes, sticky spills and pet waste, and is overpriced at full retail, making it worth buying mainly on sale.
tomsguide.comhands-on ↗4/5A premium robot vacuum/mop with excellent suction, obstacle handling, and a threshold-climbing chassis that excels at pet hair and debris, though its mopping is streaky and inconsistent for the high price.
zdnet.comhands-on ↗4/5The Saros 20 is Roborock's best flagship vacuum-mop yet, with standout carpet cleaning, better obstacle avoidance and taller threshold climbing, making it a worthwhile long-term buy for those willing to pay a premium.
techadvisor.comhands-on ↗4/5A powerful, feature-rich flagship robot vacuum and mop that cleans carpets and hard floors very well and sets up quickly, but its high price, awkward scheduling, and tendency to get stuck or snag small items hold it back.
techradar.comhands-on ↗4.5/5A top-tier, premium robot vacuum that cleans and mops very well, navigates reliably, and handles thick rugs and tall thresholds thanks to its upgraded lifting chassis, though it is pricey and more than many homes need.

Questions
Is the Roborock Saros 20 worth upgrading from the Saros 10R?
TrustedReviews and Business Insider both say it is only an incremental step over the Saros 10/10R, with little reason to upgrade. ZDNet did measure it picking up about five times as much sand on medium-pile carpet as the Saros 10R.
How well does the Roborock Saros 20 mop?
Reviewers disagree: TrustedReviews said it removed coffee, wine and mud in one pass and TechRadar found it streak-free, while Tom's Guide found it streaky and patchy. Five of 7 experts noted that sticky or dried-on messes needed extra passes or manual cleanup.
How high a threshold can the Saros 20 climb?
Reviewers report it climbing thresholds of about 3.4 inches (8.7–8.8cm), including double thresholds, and Vacuum Wars said it tied its record on a 57mm threshold. TrustedReviews noted it still could not climb one large step in a Victorian home.
Does the Roborock Saros 20 get tangled with hair?
Four expert reviews specifically report no tangling, including Vacuum Wars' test with 7-inch hair. Pet-hair pickup on carpet was mixed, with Vacuum Wars measuring 78% and Tom's Guide 70%, while TechRadar and ZDNet praised it for pet hair in carpet.
