All robot vacuums. Every figure below is placed against the whole class, so a gap can be read against how much the class itself varies.
Where each one suits you.
The conditions each robot was assessed against, side by side. Rows marked in gold are where these machines genuinely differ.
| Condition | DJI ROMO A2 | Saros 20 Flow Complete |
|---|---|---|
| Home size | ||
| Under 1,500 sqftthey differ | DependsDJI publishes no runtime or coverage area for the A2, so single-run coverage is unconfirmed. | GoodHandles compact homes easily; suction and LiDAR mapping comfortably cover a small floor plan, though the dock automation is more than most small spaces need. |
| 1,500 – 3,000they differ | DependsOnly a 2.5-hour, 55 W charge time is published; runtime per charge is unknown. | Good36,000 Pa suction and retained multi-room LiDAR maps suit mid-to-large floor plans across several rooms. |
| Over 3,000they differ | DependsNo runtime, coverage area or independent large-home test has been published for this model. | GoodMulti-level maps and a self-servicing dock handle large multi-floor homes with minimal owner intervention. |
| Primary floors | ||
| Hard floors | GoodThe swinging mop arm and self-cleaning base station target sealed hard floors, per DJI. | GoodRoller mop refreshed with clean water and 36,000 Pa suction target sealed hard floors, the surface it is built for. |
| Low / medium pilethey differ | DependsDJI has not published a mop lift height for carpet, and no independent rug test exists. | GoodCarpet detection lifts the mop 15 mm and raises suction, so low-pile rugs are cleaned without wetting. |
| High pile / shag | DependsNo mop lift figure or independent carpet test is published for this model. | DependsMop lifts only 15 mm and the roller is built for hard and low-pile; suction retention on deep pile is not independently tested for this SKU. |
| Mopping needs | ||
| Vacuum only | GoodStrong vacuum; the mop lifts or detaches when not needed. | GoodStrong vacuum; the mop lifts or detaches when not needed. |

A robot being poor for a condition is a fact about fit, not a fault. “Depends” means the record names a limit worth reading, not that the answer is unknown.
How far apart is a long way?
A number only means something next to the spread it sits in. Each track is the real range across every classified robot in the class, with the median marked.

Not compared, because fewer than two of these robots carry a published figure: Price, Runtime, Noise, Weight, Height.
What the numbers leave out.
Written on each record, and the only thing here every robot on the site carries.
The trade-off
What each design gives up to be good at what it is good at.
DJI ROMO A2
Legs and a swinging LiDAR arm solve ledges and furniture gaps, and both are new mechanisms nobody outside DJI has tested for durability.
Local Data Mode is the privacy answer, and it is a Q4 2026 promise rather than a feature that ships in the box.
Roborock Saros 20 Flow Complete
You are paying flagship money for Roborock’s most automated dock yet and a roller-mop design only weeks into public hands.
The roller washes itself continuously so pad swaps end, but a jammed roller or skipped detergent and water refill becomes the new weekly upkeep.
Who each one is wrong for
Stated by the record itself. A robot being wrong for a household is a fact about fit, not a fault.
DJI ROMO A2
- US buyers wanting ordinary domestic retail and support
- DJI's launch materials name no US price, retailer or ship date, so a US household would be buying through import channels.
- Owners who want a plumbed, hands-off water supply
- The A2 in Europe ships with a water-tank base station; clean and dirty water tanks still need refilling and emptying by hand.
- Buyers who need a published runtime or robot size
- DJI has not published a runtime or the robot's dimensions for the A2, only a 2.5-hour charge time at 55 W.
- Buyers waiting for independent test results
- Press coverage of the launch did not include hands-on testing, so every performance figure available is DJI's.
Roborock Saros 20 Flow Complete
- High-pile or shag carpet households
- The roller mop is built for hard and low-pile floors; suction and mop behavior on deep pile is not independently documented for this SKU and the mop lifts only 15 mm on carpet.
- Budget-constrained buyers
- Listed near $1,700 with the dock, this is flagship-tier pricing; a mid-range robot vacuum covers routine scheduled cleaning for a fraction of the five-year cost.
- Compact single-floor apartments
- The suction, dock automation and threshold system exceed what a small single-level home needs; a cheaper model would do the same daily job in that space.
- Owners wary of camera-based navigation
- Reactive AI uses an onboard camera that processes imagery for object detection, and Roborock has not published a device-specific privacy disclosure for this SKU.
- Buyers wanting an established reliability record
- This roller-mop configuration reached the US market in September 2026; no long-term owner reports or independent durability data exist for it yet.
What stays your job
The upkeep ownership hands back to you, whatever the autonomy level says.
DJI ROMO A2
- As needed: Refill the base station’s clean-water tank and empty the dirty-water tank.
- Weekly: Check the DualSweep side and roller brushes for hair.
- Monthly: Wipe the LiDAR windows, fisheye sensors and the leg mechanism.
- As needed: Replace the base station dust bag, which DJI rates within its 365-day maintenance claim.
- As needed: Replace mop pads, brushes and filters as they wear.
Roborock Saros 20 Flow Complete
- Weekly: Check the RockDock clean and dirty water tanks and the detergent reservoir, and rinse the roller mop.
- Monthly: Inspect the roller track and wipe down the AdaptiLift chassis mechanism.
- Monthly: Clean the RetractSense LiDAR turret and the Reactive AI camera lens for accurate obstacle detection.
- Every 3-6 months: Replace the side brush and dock filter per the maker’s service schedule.
- Annually: Replace the roller mop and main brush per maker wear guidance.
- As needed: Replace the sealed dust bag (about every 1-2 months) and refill the detergent dispenser.
How much each of these is standing on.
Classifications rest on different depths of evidence. A pre-release assessment and a verified one are not the same kind of claim.

Evidence status counts the sources behind a classification, not their kind. A high count can be maker documentation and price coverage, so read it as how much was reviewed rather than as independent testing. How we weigh evidence.
