What reviewers say

Both reviewers found strong everyday vacuuming and useful threshold handling. TechRadar praised pet-hair pickup and even mopping, although sticky spills still needed manual cleaning. Tom's Guide found patchy mopping and occasional detached pads on cables, and its carpet hair test left more debris behind. Both described the dock as reducing routine upkeep.

Task and control

Form: Robot vacuum
Use: Floor cleaning
Phone app: Yes
Intended use: Indoor floor vacuuming and mopping. Threshold-crossing claims do not establish staircase climbing.
Autonomy: SmartPlan 3.0 schedules and adapts cleaning with multi-floor maps and zone settings. Obstacle recognition is a manufacturer capability claim, rather than a guarantee that every cable or small object will be avoided.
Remote control: Roborock app, onboard buttons and built-in voice assistant; RGB camera supports remote viewing and video calls.
Regional availability: The official UK store lists the Saros 20 SKU RRUK-Saros205-M1 as available for ordering on 3 October 2026. Saros 20 Set is the same robot with extra dust bags and mop pads, rather than a different generation.
Release details: TechRadar records European sales from February 2026 and later UK, US and Australian availability in March. A maker notice establishing the first retail date was not found, so the headline date is left unpublished.

Hardware

Height: 79.8 mm
Width: 350 mm
Depth: 353 mm
Camera: Yes
Microphone: Yes
Wi-Fi: Yes
Bluetooth: Yes
Sensors: StarSight Autonomous System 2.0 uses front and rear navigation sensing, 3D time-of-flight and an RGB camera; wall, cliff and carpet sensors are identified in the manual.
Camera: RGB camera for obstacle recognition and remote viewing. The manufacturer warns that obstacle and stain recognition depend on conditions and app settings.
Audio: Microphones and a built-in voice assistant; the manual identifies microphone locations.
Connections: Manual lists 2.4 GHz and 5 GHz Wi-Fi, with regional indoor-use restrictions on some 5 GHz bands, and Bluetooth LE 5.4.
Size and weight: Robot 350 × 353 × 79.8 mm. The UK store publishes 15.89 kg for robot plus dock, not robot-only weight; that combined figure is not used as the robot's weight. Claimed access under 79.5 mm furniture involves slight front-structure compression and can cause scraping.
Accessories: Robot, multifunction dock, dock base, power cable and rotating mop modules. Set bundle adds two dust bags and two mop pads. Gallery scenes are manufacturer illustrations of domestic use.

Battery

Battery capacity: 6,400 mAh
Automatic dock return: Yes
Battery: 14.4 V, 6,400 mAh typical lithium-ion battery, as specified in the CE manual. A maker runtime under defined cleaning conditions was not established from these sources.
Charging: Automatically returns to the dock after cleaning or when charge is low, and resumes incomplete cleaning after charging. Begin from the dock and keep the dock in place for reliable return.
Dock: RockDock automatically empties dust, refills the robot from its water tank and doses detergent. Maker maximum mop-washing water temperature 100°C and drying air 55°C; these are dock functions, not temperatures applied to the floor. Base and dust-bag drying are also supported.

Cleaning

Suction (maker's claim): 36,000 Pa
Mopping: Yes
Automatic emptying: Yes
Automatic mop washing: Yes
Navigation: StarSight 2.0 3D time-of-flight navigation with RGB obstacle recognition and lateral sensing. No raised navigation turret is required.
Cleaning: DuoDivide split main brush and extendable FlexiArm side brush. The chassis, main brush and mop modules adjust height according to the cleaning mode. Claimed dynamic cleaning for carpet pile up to 30 mm needs enabling in the app.
Mopping: Two rotating mop discs; one extends towards edges. Pads can be lifted and automatically left at the dock for vacuum-only work. Maker maximum downward mop force 13 N.
Suction conditions: Maximum 36,000 Pa manufacturer suction claim. This is not a measured pickup result and does not establish comparative cleaning performance across brands.
Obstacle clearance: Maker single-threshold claim up to 45 mm; double threshold up to 45 + 43 mm requires a gap greater than 120 mm and no more than 140 mm in its laboratory test. The 88 mm total is not a single vertical-step clearance.
Maintenance: Manual calls for main-brush cleaning every two weeks, side-brush cleaning monthly and tank/filter care. Clean-water filling, dirty-water emptying and replacement dust bags remain necessary despite the dock automation.
