Saros 20
4 review sources: 3 written reviews and 1 video reviewRead the findings →Roborock's new flagship vacuum and mop, with a low body that gets under furniture and over high thresholds. It's very strong on hard floors and good with pet hair. It's less sure-footed on thick carpet and around clutter.

What reviewers found
RTINGS, TechRadar, Expert Reviews and Vacuum Wars all found strong hard-floor cleaning and a dock that takes on much of the routine work. Carpet pickup and obstacle avoidance varied more from test to test. The home reviews were keener than the lab, which found real limits on both. So even with this robot, a tidy floor still matters, especially if you have cables or pets.
RTINGS, lab test · TechRadar, hands-on, 1 month at home, Apr 2026 · Expert Reviews, hands-on, Apr 2026
Hard floors
Reviewers rate it highlyEvery test found it clears hard floors well. RTINGS saw very little left around the edges, Expert Reviews got a perfect result in its standard cleaning tests, and Vacuum Wars and TechRadar also found everyday pickup strong.
Carpet and rugs
Mixed resultsThe home tests were keen: Expert Reviews saw it lift itself to clean thick, fluffy rugs without rucking them, and Vacuum Wars measured above-average sand removal from medium pile. In the lab, RTINGS found carpet pickup only decent, weaker with fine particles and along edges.
Pet hair
Reviewers rate it highlyTechRadar was especially pleased with pet-hair removal, and Expert Reviews found it pulled dog hair out of deep carpet and along skirting boards. Vacuum Wars got above-average pickup of flattened hair and no hair at all wrapped round the brush.
Mopping
Reviewers rate it highlyVacuum Wars called the mopping a big step forward for Roborock, lifting dried coffee without leaving excess water, and Expert Reviews saw dried coffee and ketchup scrubbed away. The toughest stains can need extra passes or the deep-clean setting, RTINGS and Expert Reviews found.
Navigation and obstacles
Mixed resultsExpert Reviews called its avoidance the best it has tested, dodging cables and a fake pet mess, and TechRadar saw only occasional odd behaviour. RTINGS found avoidance inconsistent on carpet and unreliable with pet waste, and Vacuum Wars rated it only slightly above average.
Dock and upkeep
Reviewers rate it highlyReviewers found the dock takes most chores off you. TechRadar mostly just filled and emptied the water tanks over a month, RTINGS rated the self-emptying and mop care, and Vacuum Wars and Expert Reviews both liked the boiling-water mop wash and hot-air drying.
App and software
Reviewers rate it highlyVacuum Wars found the app offers some of the most precise controls around, and Expert Reviews said it keeps everyday settings up front despite the long feature list, with only slightly untidy 2D maps to complain about.
Noise
Not enough evidenceOnly one review we use judged the noise: TechRadar found the dock's drying cycle audible during a month of use. Nobody has reported on how loud the robot is while cleaning.
Reliability and support
Not enough evidenceNone of the reviews we use has run it long-term or judged Roborock's support yet, so there's nothing to go on beyond the first few weeks of testing.
Value
Not enough evidenceOnly Expert Reviews judged value, and it found cheaper robots such as the Eufy C28 and Tapo RV50 do most of the job for about half the price, making the Saros 20 worth it mainly if you need its climbing and avoidance.
Verdicts come from independent, hands-on, finished reviews. An area needs at least two of them before we say more than “Not enough evidence”. We don't score robots ourselves. How this works
Convincing on hard floors
RTINGS found almost complete pickup on hard floors, edges included. TechRadar also praised the everyday vacuuming and the reach of the extending brush and mop. If your home is mostly hard floors, that's a good reason to pick it. Just don't buy it for the advertised suction figure, because that number on its own doesn't tell you how much dirt it collects.
Keep carpet expectations realistic
TechRadar was especially impressed by how it removed pet hair, but RTINGS called general carpet pickup decent rather than exceptional, particularly with fine particles and along edges. Expect help with routine upkeep, and keep a normal vacuum for a proper clean. One keen home result isn't enough to call it great on every carpet.
The adjustable body earns its keep
TechRadar watched the chassis adapt mid-clean and liked the low profile with no navigation tower on top. That's what makes it interesting for thick rugs, raised transitions and low furniture. The reviewer had a fairly simple home, though, so nobody has yet confirmed the advertised maximum climbing height. Wait for a measured test if your thresholds are near the limit.
Obstacle avoidance isn't effortless
RTINGS found avoidance inconsistent, particularly on carpet, and pet-waste avoidance unreliable. TechRadar's experience was much more positive, with only occasional odd behaviour. Nobody has shown why the two differ. If your floors have toys, cables or an accident-prone pet, tidy up first rather than trusting the sensors to cope on their own.
A helpful dock, with some noise
A month with TechRadar mostly meant filling and emptying the water tanks, though the dust-bag drying was audible. RTINGS also rated the self-emptying and mop care, while finding tougher stains needed extra passes. What you really get is fewer repeated chores, as long as the station fits your space and the avoidance limits suit your household.
This covers the rotating-mop Saros 20. The Saros 20 Sonic is a different model with its own page.
Our take
Should you buy the Saros 20?
Best for: Homes with raised door thresholds and low furniture. Skip it if: You have thick carpets or usually leave clutter on the floor.
Consider the Saros 20 for a home with mainly hard floors, low furniture and raised doorway thresholds. Reviews were less consistent on deep-carpet pickup and small-object avoidance. Clear cables and check for pet accidents before each clean.
The standard Saros 20 has a low body without a raised navigation turret and an adjustable chassis for thresholds. Roborock lists its height as 7.98cm. The dock empties dust and washes and dries the spinning mop pads. The Saros 20 Sonic is a separate model with a different mop and navigation system.
All four testers rated hard floor cleaning highly. TechRadar also praised pet hair pickup, and Vacuum Wars found no hair wrapped round the brush. Expert Reviews saw it cross thick rugs without rucking them, but RTINGS found only decent carpet pickup, especially with fine debris and along edges. Clutter is the other doubt. Expert Reviews saw it dodge cables and fake pet mess, but RTINGS found pet-waste avoidance unreliable and Vacuum Wars rated it only slightly above average. TechRadar mostly just filled and emptied the water tanks over a month. Expert Reviews found cheaper robots such as the Eufy C28 and Tapo RV50 do most of the job for about half the price.

Before you buy
The questions people ask about this one
Will it avoid cables and pet mess?
Sometimes. RTINGS found it inconsistent, especially on carpet, while TechRadar had few problems. Treat it as a robot that needs a tidy floor, not one you can leave alone with a puppy.
Does it fit under low furniture?
Better than almost anything. It's 7.98cm tall with no turret on top, according to the specifications. Measure the gap under your sofa before you buy; most robots need 10cm or more, and this one is the reason to choose it.
Can it leave the mops in the dock?
Yes. Roborock’s UK product page lists detached mops for vacuum-only mode. That's separate from lifting the attached pads when it crosses carpet. If you don't want wet pads touching anything, detach them and run it on vacuum only.
How big is the dock, and is it loud?
The RockDock washes mops with hot water, dries them, empties the bin and refills water, so it's a large unit, per the specifications. Drying is audible; TechRadar noticed it during a month of use. Plan where it lives before it arrives.
Is the 36,000Pa figure real?
It's Roborock's advertised pressure, taken from the specifications, not a cleaning result. The independent tests show strong hard-floor pickup, and that's what matters. Don't buy on the number, and don't compare it with other brands' numbers either.
Saros 20 or Saros 20 Sonic?
They're different robots. Roborock’s standard Saros 20 and the Sonic differ in both mopping and navigation. The standard model uses spinning pads and has no turret on top; the Sonic has a vibrating mop and a retracting laser turret. Read the reviews for the exact version you're considering, because results for one won't necessarily hold for the other.
Alternatives
Other robot vacuums to compare.
X60 Pro Ultra Complete
Why consider it: Cleaning power, obstacle-crossing hardware and the dock are consistently praised.
The compromise: Reports of getting stuck, long cleaning times and high water use make it less effortless than the spec sheet suggests.
DEEBOT X12 OmniCyclone
Why consider it: Owners like the bagless cyclone bin, anti-tangle setup and general cleaning reliability.
The compromise: Some owners prefer the older X11 or cheaper T90 for mopping, so the price premium is hard to justify on cleaning alone.
X60 Max Ultra Complete
Why consider it: Low-profile access and capable obstacle handling.
The compromise: Mixed pickup results and modest battery efficiency.
Saros 20 head to head
Head to head
Roborock Saros 10 vs Saros 20
Our verdict: Buy the Saros 10 unless you need the climbing. It's cheaper, its spec sheet is fully verified, and the 20 only clearly wins on thresholds and the hot-water dock.
