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.Household floor vacuuming and mopping. Complete supplies additional cleaning consumables; it is not a separate robot hardware generation.
Autonomy–CleanGenius selects cleaning routines; selectable vacuum, mop, combined and mop-after-vacuum modes. Automatic return to the dock for charging followed by cleaning resumption.
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.Dreamehome app, built-in voice control and supported Alexa, Siri and Google Assistant integrations; third-party voice control requires a compatible voice device.

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.–
CameraDual fisheye vision sensors; remote video supported through the DJI Home app.AI camera for obstacle recognition and remote pet monitoring; cloud photo storage is offered, subject to account and regional functionality.
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.Built-in voice control; voice requests and camera functions are distinct from general autonomous household work.
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 × 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.
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.–
Battery
Battery life (maker's claim)About 3 hours vacuuming in Quiet mode, with around 12% charge remainingUp to 220 minutes, vacuuming and mopping in Quiet mode
Battery capacity–6,400 mAh
Automatic dock return–Yes
BatteryBattery capacity is not stated in the exact ROMO 2 maker sources read; earlier ROMO capacity is not transferred.6,400 mAh battery.
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.Maker 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.
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.Up 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.
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.Automatic 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.

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.VersaLift retractable DToF sensor, AI camera and 3D structured-light obstacle detection. The maker claims recognition of up to 200 obstacle types under laboratory conditions.
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.HyperStream 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.
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.Dual 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.
Dust capacity–Robot 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 capacity–Dock clean-water tank 4.5 L and used-water tank 4.0 L; optional water hookup arrangements depend on region and installation.
Suction conditions36,000 Pa is maximum fan pressure measured in DJI laboratory tests, not a universal cleaning-performance score.–
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 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.
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.Replace 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.
