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 | Dreame Aqua20 Pro Ult… | Dyson R1 Nurovi Dry |
|---|---|---|
| Home size | ||
| Under 1,500 sqftthey differ | DependsRuntime and coverage per charge are unpublished before launch. | GoodA 120-minute run and saved LiDAR maps cover a compact home comfortably in one pass. |
| 1,500 – 3,000 | DependsNo battery or runtime figure exists yet to confirm single-run coverage at this size. | DependsThe 120-minute run suits mid-size homes, but Dyson does not state the R1 recharges and resumes, so a single large run can stop short. |
| Over 3,000 | DependsNo runtime, coverage area or large-home test has been published. | DependsNo published coverage figure for homes this size, and no documented recharge-and-resume, so a full clean may take several sessions. |
| Primary floors | ||
| Hard floors | GoodSteam pretreatment plus a 300 rpm roller at 18 N target sealed hard floors. | GoodBuilt around hard floors: 21,000 Pa rated suction plus an ultrasonic sensor that separates hard floor from carpet. |
| Low / medium pilethey differ | DependsThe mop lifts 15 mm and a guard covers the roller on carpet, but rug behavior is untested. | GoodTwin-capture separation and 21,000 Pa rated suction handle low-pile carpet; the brush bar is built to resist hair wrap. |
| High pile / shag | DependsA 15 mm lift may not clear dense pile, and no carpet test exists before launch. | DependsThe 21,000 Pa figure is a peak Dyson claim with no independent high-pile test, so deep and shag pile performance is unverified. |
| Mopping needs | ||
| Vacuum only | GoodStrong vacuum; the mop lifts or detaches when not needed. | GoodVacuum-only robot — matches a vacuum-only need. |
| Light moppingthey differ | GoodActive mopping system covers routine floors easily. | PoorThis model has no mopping function. |
| Frequent moppingthey differ | GoodPressure or rotating mop with self-wash is built for frequent mopping. | PoorNo mop at all; choose a vacuum-and-mop robot instead. |
| Upkeep you accept | ||
| Regular upkeep | GoodAny robot vacuum suits an owner who accepts regular upkeep. | GoodAbout 25 minutes of upkeep a month. |
| Some upkeepthey differ | DependsUpkeep time a month is not verified. | GoodAbout 25 minutes of upkeep a month. |
| Minimal upkeepthey differ | DependsUpkeep time a month is not verified. | GoodAbout 25 minutes of upkeep a month, and the dock empties the bin. |
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, Charge time, 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.
Dreame Aqua20 Pro Ultra Roller X Complete
Steam is the headline, and a 356°F source is also a new heating system that no one has run for a season yet.
Dreame’s 99.999% bacteria figure is its own SGS-commissioned test: a claim, not a measurement anyone else has repeated.
Dyson R1 Nurovi Dry
At $549 the R1 keeps the R2’s LiDAR navigation and the same 21,000 Pa suction on the same chassis. What the lower price removes is wet cleaning, not sensing: the R2 adds mop hardware and a washing dock, and both robots map the same way.
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.
Dreame Aqua20 Pro Ultra Roller X Complete
- Buyers who need one in the US
- Dreame has announced dates and prices for Germany, Austria, Spain, Portugal and the UK only; no US price or date exists.
- Buyers who want a record before buying
- It goes on sale 21 Sep 2026, so there are no owner reports or independent tests; independent testers treat every figure as a manufacturer claim.
- Sealed or heat-sensitive floor finishes
- The system applies 356°F steam; Dreame has not published which floor finishes the steam step is suitable for.
- Buyers who need battery and runtime figures
- Dreame has not published battery capacity, runtime or robot dimensions for this model.
Dyson R1 Nurovi Dry
- Anyone who needs mopping in the same machine
- The R1 has no mop hardware at all. Readers who want wet cleaning need the R2 Wash+Dry or the R3 Spot+Scrub UV instead of this vacuum-only model.
- Buyers who want independent test data before paying
- No independent reviews, teardowns or owner reports exist yet. Every published figure, including the 21,000 Pa suction, traces back to Dyson's own launch materials.
- Shoppers comparing on battery or sound figures
- Dyson publishes run time and charge time but no battery capacity, no sound rating and no onboard-bin volume for the R1, so there is nothing to compare on those numbers.
- Large multi-room homes needing guaranteed full coverage
- Dyson does not state that the R1 recharges and resumes an unfinished map, and no coverage figure for big layouts has been tested, so a single run may stop short.
What stays your job
The upkeep ownership hands back to you, whatever the autonomy level says.
Dreame Aqua20 Pro Ultra Roller X Complete
- As needed: Refill the dock’s clean water and empty its dirty water, which also feed the steam and AquaRoll systems.
- Weekly: Check the HyperStream DuoBrush 2.0 main brush and side brush for debris.
- Monthly: Wipe the AstroVision camera windows and VersaLift sensor.
- As needed: Replace the dock dust bag, filter and roller mop as they wear.
- As needed: Clear mineral buildup from the steam outlets if the app or manual calls for it.
Dyson R1 Nurovi Dry
- Every 3-6 months: Empty the dock’s bin; the dock is bagless and empties the robot after each run.
- Monthly: Clean the Twin-capture debris separator to maintain suction.
- Monthly: Wipe down and inspect the extending side sweeper for hair wrap.
- Every 3-6 months: Clean or replace the robot and dock filters; Dyson has not published an interval.
- As needed: Clear the anti-tangle brush bar of tangled hair and debris.
- Annually: Inspect wheels and sensors for dust buildup.
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.
| Robot | Evidence status | Sources reviewed | Last assessed |
|---|---|---|---|
| Dreame Aqua20 Pro Ultra Roller X Complete | Pre-Release | 4 | Sep 2026 |
| Dyson R1 Nurovi Dry | Provisional | 5 | Oct 2026 |
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.
