Updated October 25, 2026
All 6 expert reviewers tested it hands-on and agree it is a top-tier vacuum, with standout suction, carpet cleaning and the ability to climb thresholds of around 8.7cm. One reviewer measured about twice the sand pickup of the Saros 10 on medium-pile carpet. Owners are cooler than experts: the owner score is 62 against an expert score of 84. Owner comments praise suction (32%), mopping (18%) and navigation (14%), while 9% criticise navigation, 5% say it gets stuck and 4% report it breaking. Failure mentions are low at 6% of owners, but every reviewer flagged the price, and one reported only a handful of trouble-free cleans in two weeks.
What each expert concluded
A 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.
Hands-on review · open the review ↗~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.
Hands-on review · open the review ↗A 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.
Hands-on review · open the review ↗The 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.
Hands-on review · open the review ↗A 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.
Hands-on review · open the review ↗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.

The short version
Living with it mostly means coming home to clean floors. It deals with thick rugs, tall door thresholds and low furniture that stop most robots. The main catches are the steep price, mopping that can be patchy on sticky spills, and the odd time it gets stuck on cords or furniture. It suits busy homes with mixed floors and pets that want a top-end robot to do the daily work.
