FormRobot vacuumRobot vacuum
UseFloor cleaningFloor cleaning
Phone appYesYes
Intended useHousehold floor vacuuming and mopping. Complete supplies additional cleaning consumables; it is not a separate robot hardware generation.Indoor floor vacuuming and mopping. Threshold-crossing claims do not establish staircase climbing.
AutonomyCleanGenius selects cleaning routines; selectable vacuum, mop, combined and mop-after-vacuum modes. Automatic return to the dock for charging followed by cleaning resumption.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 controlDreamehome app, built-in voice control and supported Alexa, Siri and Google Assistant integrations; third-party voice control requires a compatible voice device.Roborock app, onboard buttons and built-in voice assistant; RGB camera supports remote viewing and video calls.
Regional availabilityThe maker US store accepts X50 Ultra and X50 Ultra Complete orders; available exact black and white retail variants are confirmed in its current product data. The US listing advertises delivery in 2–5 business days, subject to checkout. UK availability is not established by the global product listing. Checked October 2026.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 detailsFirst actual retail delivery date is not established by the exact maker sources read. The ProLeap technology's Q4 2024 introduction does not establish this robot's first-sale date.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 A maker notice establishing the first retail date was not found, so the headline date is left unpublished.

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.
CameraAI camera for obstacle recognition and remote pet monitoring; cloud photo storage is offered, subject to account and regional functionality.RGB camera for obstacle recognition and remote viewing. The manufacturer warns that obstacle and stain recognition depend on conditions and app settings.
AudioBuilt-in voice control; voice requests and camera functions are distinct from general autonomous household work.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 weightRobot 350 × 350 × 89 mm with VersaLift sensor retracted, or 350 × 350 × 111 mm raised. Robot weight 4.53 kg. Dock dimensions 457 × 340 × 590 mm as ordered by the maker, weight 9.09 kg. Ensure flat furniture undersides and additional clearance to prevent enclosure scratches in low-clearance mode.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 life (maker's claim)Up to 220 minutes, vacuuming and mopping in Quiet mode–
Battery capacity6,400 mAh6,400 mAh
Automatic dock returnYesYes
Battery6,400 mAh 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.
ChargingMaker claims 30% faster charging than its robot vacuums without fast charging; off-peak charging can be selected. No exact full-charge duration is assigned from this relative claim.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.
Runtime conditionsUp to 220 minutes in vacuuming-and-mopping Quiet mode. Coverage up to 205 m² was tested separately in vacuum-only Quiet mode. Manufacturer laboratory claims; the coverage and runtime describe different workloads.–
DockAutomatic dust emptying, robot water refill, detergent dispensing, mop-pad washing/drying and washboard cleaning. Fresh and dirty dock water tanks still need filling and emptying unless an appropriate optional regional hookup is fitted.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.

NavigationVersaLift retractable DToF sensor, AI camera and 3D structured-light obstacle detection. The maker claims recognition of up to 200 obstacle types under laboratory conditions.StarSight 2.0 3D time-of-flight navigation with RGB obstacle recognition and lateral sensing. No raised navigation turret is required.
CleaningHyperStream dual anti-tangle brushrolls, extendable side brush and five suction levels. Maximum 20,000 Pa is a maker laboratory suction claim; it does not establish debris pickup relative to another brand.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.
MoppingDual rotating mop pads with MopExtend edge reach; automatic mop lifting or dock detachment for selected carpet modes. Up to 80°C dock mop-washing water, hot-air drying, automatic detergent dispensing and washboard cleaning. The dock washing temperature is not the temperature of the entire floor-mopping process.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.
Dust capacityRobot dustbin 395 ml according to the exact current maker X50 comparison column; the adjacent 300 ml value belongs to X40 Ultra. Dock disposable dust bag 3.2 L. Claimed 100 days between bag replacements depends on household dirt and use.–
Water capacityDock clean-water tank 4.5 L and used-water tank 4.0 L; optional water hookup arrangements depend on region and installation.–
Obstacle clearanceMaker laboratory maximum 42 mm for a single vertical step, or 60 mm total across two steps with a gap greater than 40 mm. These are threshold conditions, not stair-climbing capability.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.
MaintenanceReplace dock dust bags, worn pads, brushes and filters, and periodically clean accessible robot/dock parts. Complete includes extra consumables rather than extra robot sensing or suction hardware.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.
