Our take
Roborock Saros 20
Strong hard-floor cleaning and useful mobility, but tests disagree on carpet pickup and avoidance. These findings concern the Saros 20, not the Sonic.
Hard-floor pickup and access around floor transitions.
Inconsistent avoidance; carpet results vary.
Early adopters who want Roborock's newest premium floor-care system.
Buyers who want a lower-cost robot or a compact dock.
- 36,000Pa claimed — an advertised pressure figure, not a cleaning score.
- Up to 8.8cm thresholds
- A 7.98cm-tall body can reach under low furniture; check the gap beneath yours.
What reviewers found
The Saros 20 receives strong praise for hard-floor cleaning, access under furniture and reducing everyday maintenance. Reviews disagree more on carpet performance and obstacle handling. Its ability to cross awkward transitions is a clearer reason to consider it than expecting it to ignore every form of clutter.
Particularly convincing on hard floors
RTINGS found near-complete pickup on hard flooring, with little remaining around edges. TechRadar also reported strong everyday vacuuming and useful reach from the extending brush and mop. This is the most consistent positive across the two tests. For a mostly hard-floor home, the evidence is more reassuring than for someone judging the robot mainly on deep carpet cleaning.
[1][2]Keep carpet expectations realistic
TechRadar was especially impressed by pet-hair removal. RTINGS found most hair was collected but described general carpet pickup as decent rather than exceptional, particularly with fine particles and room edges. We would expect help with routine upkeep, while retaining a conventional vacuum for a thorough clean. The sources do not justify turning the more enthusiastic result into a universal claim.
[1][2]The adjustable body has practical value
TechRadar saw the chassis adapt during cleaning and liked the low profile without a roof-mounted navigation tower. That combination makes the model interesting where thick rugs, raised transitions and low furniture frustrate another robot. Its reviewer had a relatively simple home, however, so the experience should not be read as a test of every advertised maximum climbing height.
[2]Obstacle avoidance is not consistently effortless
RTINGS found inconsistent avoidance, particularly on carpet, and unreliable pet-waste avoidance. TechRadar's overall navigation experience was much more positive, with occasional odd behaviour. There is no demonstrated explanation for the difference in these reports. A household with toys, cables or accident-prone pets should still prepare the floor rather than equate advanced sensors with dependable unattended safety.
[1][2]A helpful dock, with ongoing noise and water jobs
TechRadar's month of use mainly required filling and emptying the water tanks, although dust-bag drying was audible. RTINGS likewise highlighted automated emptying and mop care as strengths, while finding tougher stains needed more work. Our reading is that the Saros 20's strongest ownership benefit is reducing repeated chores across accessible rooms, provided its station fits comfortably and its avoidance limitations suit your household.
[1][2]This assessment concerns the rotating-mop Saros 20. Saros 20 Sonic is a different model; its feedback has not been merged here.
