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 | Eureka J15 Ultra | Dyson R1 Nurovi Dry |
|---|---|---|
| Home size | ||
| Under 1,500 sqft | GoodCompact homes benefit from auto-dock refill and mop retraction; no range constraints for sub-1500 sqft single-floor layouts. | GoodA 120-minute run and saved LiDAR maps cover a compact home comfortably in one pass. |
| 1,500 – 3,000they differ | GoodIdeal fit range. Runtime and dock refill cadence scale well for 2-3 scheduled runs weekly across mixed floor types. | 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 | DependsRequires multiple passes per cycle; runtime constraints may necessitate 2-3 sessions weekly for thorough coverage. | 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 | GoodScrubExtend mopping targets hard floors; mop pads run continuously on sealed wood, tile, and vinyl. | GoodBuilt around hard floors: 21,000 Pa rated suction plus an ultrasonic sensor that separates hard floor from carpet. |
| Low / medium pile | GoodScrubExtend automatically retracts mop on detected low-pile carpet. Vacuuming performance is standard for the category. | GoodTwin-capture separation and 21,000 Pa rated suction handle low-pile carpet; the brush bar is built to resist hair wrap. |
| High pile / shagthey differ | PoorOwner reports on Eureka mop-combos document reduced suction effectiveness on deep shag carpet; dedicated vacuums recommended. | 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 | GoodAbout 90 minutes of upkeep a month. | GoodAbout 25 minutes of upkeep a month. |
| Some upkeepthey differ | DependsAbout 90 minutes of upkeep a month, which is over an hour. | GoodAbout 25 minutes of upkeep a month. |
| Minimal upkeepthey differ | PoorAbout 90 minutes of upkeep a month, which is over an hour. | 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: Runtime, Charge time, Noise, Weight.
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.
Eureka J15 Ultra
Mopping adds capability but requires weekly mop-pad maintenance; one feature trades hands-off claims for consumable churn.
IntelliView pairs LiDAR with an RGB camera, an LED lamp and a line laser to recognize objects, so the obstacle avoidance runs on a camera operating inside the home. The recognition that keeps the robot off cables and pet waste is the same hardware a privacy-sensitive household has to accept.
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.
Eureka J15 Ultra
- Homes with primarily high-pile or deep carpet
- Mopping mechanism targets hard floors. Owner reports for Eureka mop-combos note reduced effectiveness on textured carpet; dedicated vacuums outperform here.
- Owners with spotty 2.4GHz-only Wi-Fi coverage
- Eureka J-series use 2.4GHz Wi-Fi exclusively. Homes with 5GHz-only networks or fragmented coverage require mesh upgrades or Wi-Fi extenders.
- Users requiring true Level IV autonomous operation
- Classification at Level III: operates in a mapped environment with occasional human intervention for edge cases. IntelliView recognizes and routes around known object types, but the robot does not adapt to settings outside the map it has been taught.
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.
Eureka J15 Ultra
- Weekly: Rinse the mop pads by hand or run a dock wash cycle; check the side brush and FlexiRazor roller for hair wrap.
- Monthly: Clean the dust filter, rinse the station tray, and refresh the 4 L clean and 3.4 L dirty water tanks.
- Every 3-6 months: Replace the 3 L dust bag; Eureka rates one at roughly 75 days, the early edge of this window.
- Every 3-6 months: Replace the mop pads once the surface mats or frays; descale the station’s water circuit with an appliance descaler, not vinegar, if mineral buildup appears.
- Annually: Replace the FlexiRazor roller brush and the filter; replacement runs 6-12 months depending on hair load, and the anti-tangle roller is built to stretch that cycle.
- Annually: Inspect the dock gaskets and charging contacts for wear.
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.

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.
