Roborock Saros 20: review
The Roborock Saros 20 suctions at 36 000 Pa, the highest figure across the whole Roborock range we track. Its RockDock® dock mops with hot water and dries with hot air automatically — but Roborock doesn't specify the mopping technology used by the robot itself.
Verdict in brief
The Saros 20 pushes Roborock's suction to its documented maximum. It's a solid choice for thick rugs and pet hair — provided you don't confuse suction power with mopping quality, the latter remaining, here, an unknown.
✓ Pros
- 36 000 Pa: the highest suction in the range
- RockDock®: hot-water mopping, hot-air drying, auto-refill
- StarSight® 2.0 navigation
- 6 400 mAh battery
✕ Cons
- Robot mopping technology not specified
- 1 289 €: the highest price in the Saros series covered here
- The cheaper Saros 20 Sonic adds a documented sonic mop
Who is it for?
Households with thick rugs and pet hair, for whom suction matters above everything else, and who don't need a sonic mop for ground-in stains.
Skip it if…
Mopping matters as much as suction to you: for 40 € less, the Saros 20 Sonic documents a mopping technology (VibraRise 5.0) that the Saros 20 doesn't specify.

At strictly identical suction (36 000 Pa), the Saros 20 Sonic costs 40 € less and additionally documents a VibraRise 5.0 sonic mop with 100 °C mopping. On paper, the Saros 20 Sonic is the more rational choice of the two, barring an unpublished difference between the two chassis.

Frequently asked questions
Is the Saros 20 the hardest-suctioning Roborock robot?
Yes, at 36 000 Pa, tied with the Saros 20 Sonic: it’s the highest figure across the whole range covered by this site.
Should you prefer the Saros 20 or the Saros 20 Sonic?
The Saros 20 Sonic, at 40 € less (1 249 € versus 1 289 €), adds the VibraRise 5.0 sonic mop and the AdaptiLift 3.0 chassis. At equal suction and a lower price, the Sonic is objectively better equipped — unless some undocumented detail differentiates the two docks.
