FormRobot vacuumRobot vacuum
UseFloor cleaningFloor cleaning
Phone appYesYes
Intended useHousehold vacuuming and mopping. P2 and A2 share the published cleaning hardware; their dock exterior and floor-deodorizer/UV functions differ. Clean More is an accessory bundle rather than a separate robot generation. This record covers the actively ordered removable-water-tank variants.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 controlDJI Home app supplies cleaning tasks, room settings, pet areas, remote video and voice calls. Vacuum & Mop, Vacuum, Mop and Vacuum Then Mop modes.Roborock app, onboard buttons and built-in voice assistant; RGB camera supports remote viewing and video calls.
Regional availabilityThe Greek DJI maker store offers P2 SKU 231321 and A2 SKU 231741 with active Buy Now, on_sale purchase state and presale false, checked October 2026. An address-dependent delivery estimate is not populated in the public page state; ordering does not promise a particular delivery day. Local delivery and checkout conditions apply.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 detailsExact first retail sale is not established by the manufacturer pages read; current ordering is confirmed separately. The record does not infer a launch date from page assets or review publication dates.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 A maker notice establishing the first retail date was not found, so the headline date is left unpublished.

SensorsBuilt-in dust-revealing light with a claimed 2,000 cm² illuminated area. Vision-based liquid detection is effective on discernibly textured surfaces with at least 0.1 lux ambient lighting and must be enabled in the app.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.
CameraDual fisheye vision sensors; remote video supported through the DJI Home app.RGB camera for obstacle recognition and remote viewing. The manufacturer warns that obstacle and stain recognition depend on conditions and app settings.
AudioRemote voice calls are supported. Frandroid's P2 test reports that French OK ROMO onboard voice control was awaiting firmware at launch; this is not a universal current-language promise.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 weightThe exact P2 and A2 manufacturer installation illustrations give robot width × depth × height 351 × 351 × 98 mm. Dock installation clearance is at least 425 mm wide, 453 mm deep and 440 mm high, with at least 400 mm above for water-tank removal and 1,000 mm in front; these clearances are not dock enclosure dimensions. Robot weight is not stated in these maker sources.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.
DurabilityMaker explicitly states that the robot and charging base are not water resistant; keep them in dry areas and avoid contact with liquids.–
AccessoriesRobot, matching water-tank dock, dock base plate, mains power cord and cleaning solution; P2 also includes floor deodorizer. Clean More adds a cleaning accessory kit.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 life (maker's claim)About 3 hours vacuuming in Quiet mode, with around 12% charge remaining–
BatteryBattery capacity is not stated in the exact ROMO 2 maker sources read; earlier ROMO capacity is not transferred.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.
ChargingAbout 18 Wh recovered in 30 minutes, providing roughly 36 minutes of Vacuum & Mop operation in maker laboratory conditions at 25°C, docked with drying disabled. Full-charge duration is not specified in these maker sources.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 conditionsMaker example of about 3 hours vacuuming in Quiet mode and approximately 178 m² cleaned, with around 12% charge remaining. This is not a vacuum-and-mop duration or a zero-charge endurance limit; environment, usage and firmware affect results.–
DockBoth docks provide high-temperature, high-pressure self-cleaning with 80°C hot water and robot dust-box drying. P2 additionally includes a floor deodorizer and dust-bag UV light; these two features are not listed for A2. Maker noise examples are about 54 dBA in Vacuum & Mop mode and 40 dBA while the dock dries, under controlled conditions. The 85% generation-to-generation reduction refers to sound energy, not decibels.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.

NavigationMillimeter-Level Obstacle Sensing 2.0 combines front-facing 3D ToF LiDAR, dual fisheye vision sensors and side 3D ToF LiDAR. The maker requires textured, non-specular surfaces with reflectivity over 20% and ambient lighting of at least 0.1 lux; mirrored or highly reflective surfaces can impair positioning.StarSight 2.0 3D time-of-flight navigation with RGB obstacle recognition and lateral sensing. No raised navigation turret is required.
CleaningDualSweep side and roller brushes have overlapping coverage. The maker's 0% hair-entanglement result used 1 g of hair in laboratory conditions and is not a guarantee for all homes. A carpet pressure plate lowers to semi-seal the suction chamber against the floor.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.
MoppingRotating mop pads and a LiDAR-guided 123° swing arm. The claimed 7.8 cm wider reach is relative to the previous generation rather than absolute extension; maker imagery also specifies 4.5 cm deeper reach under floating furniture. Straight-wall coverage claims do not guarantee removal of all dirt in every corner.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 conditions36,000 Pa is maximum fan pressure measured in DJI laboratory tests, not a universal cleaning-performance score.Maximum 36,000 Pa manufacturer suction claim. This is not a measured pickup result and does not establish comparative cleaning performance across brands.
Obstacle clearanceUp to 40 mm single step or 85 mm total double step under DJI laboratory conditions. For the double step, the lower step is at most 40 mm high and 200–220 mm wide; the upper step adds at most 45 mm. Actual crossings vary with environment and firmware.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.
MaintenanceThe 365-day maintenance-free claim applies only to the dock washboard, is theoretical laboratory evidence and excludes tank refilling and consumable replacement. Removable water tanks, dust bags, filters, brushes and mop pads still need attention.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.
