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 | R2 Nurovi Wash+Dry | Roomba Combo j5+ |
|---|---|---|
| Home size | ||
| Under 1,500 sqft | GoodLiDAR mapping and a 90-minute maximum run time, per Dyson, cover a compact floor plan in one charge. | Good120-minute runtime covers compact homes; mopping bin adds flexibility. |
| 1,500 – 3,000they differ | DependsDyson publishes a 90-minute run time but no coverage area per charge, so mid-size homes are unconfirmed. | GoodIdeal fit for mixed-use homes; vacuum and mop on separate schedules. |
| Over 3,000 | Depends90-minute run time, 6.5-hour charge, and no published recharge-and-resume behavior for a home this size. | DependsVery large homes require split runs; bin swaps add coordination overhead. |
| Primary floors | ||
| Hard floors | GoodTwin-capture brush bar and suction pick up debris while the rotating pads wash hard floors in the same run. | GoodPrimary design target; mopping works well on sealed hard surfaces. |
| Low / medium pile | DependsUltrasonic sensor detects carpet and adjusts suction; Dyson publishes no mop-lift figure for crossing rugs. | DependsVacuum handles low pile; mopping is optional and user-scheduled. |
| High pile / shagthey differ | DependsNo independent deep-pile test published, and Dyson does not state whether the wash pads lift clear of pile. | PoorMopping is not suitable for carpet; firmware prevents water spillage on detected carpet. |
| Mopping needs | ||
| Vacuum only | GoodStrong vacuum; the mop lifts or detaches when not needed. | GoodVacuums first; the mop pad is optional. |
| Light mopping | GoodActive mopping system covers routine floors easily. | GoodFlat mop pad handles light, routine wiping of hard floors. |
| Frequent moppingthey differ | GoodPressure or rotating mop with self-wash is built for frequent mopping. | DependsA dragged pad freshens floors but lacks the pressure or scrubbing for heavy, frequent mopping. |
| You want to… | ||
| Empty bin myself | GoodThe dock empties the bin and washes the pads, so hands-on upkeep is lighter than this option allows. | GoodWeekly pad washing and bi-weekly bin swaps are required; moderate hands-on effort. |
| Empty occasionally | GoodBin emptying every few months and occasional spare-part swaps are the main owner tasks Dyson describes. | GoodDock handles vacuum auto-empty; mopping requires app scheduling and water refills. |
| Set-and-forgetthey differ | GoodDock self-empties, washes pads at 167°F, dries them at 113°F and refills; bin rated up to 90 days. | PoorWeekly bin swaps, pad washing, and water refills are mandatory tasks. |
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: Noise.
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.
Dyson R2 Nurovi Wash+Dry
Corner reach is the whole reason for the triangle pads, and the only public demo never pointed them at a corner.
Ninety days between bin emptyings is Dyson’s internal test figure; Dyson itself says real intervals vary with debris, habits and floor type.
iRobot Roomba Combo j5+
The Combo bin gives you both jobs in one pass, but self-emptying is disabled for as long as it is installed, so those runs end with a bin to empty by hand.
The bin sets the mode, which makes the behavior easy to predict, but the robot cannot decide to start a wet run on its own: whichever bin is fitted is what the next scheduled run does.
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.
Dyson R2 Nurovi Wash+Dry
- Buyers who need independent cleaning tests before buying
- No hands-on review had been published by 14 Sep 2026. Expert Reviews watched a Dyson event demo handle salt and water spills, but the demo never showed the R2 cleaning a corner.
- Homes over 3,000 sq ft expecting one-charge coverage
- Dyson publishes a 90-minute maximum run time and a 6.5-hour charge time, but no coverage area per charge and no statement on recharge-and-resume behavior for long runs.
- Homes with rugs in rooms that also get mopped
- An ultrasonic sensor detects carpet and adjusts suction, but Dyson's product and FAQ pages do not state whether the wash pads lift or detach before the robot crosses a rug.
- US shoppers without a Costco membership
- Vacuum Wars describes the US launch as a Costco exclusive, and no other US retailer appeared in the sources read. Dyson's own UK store sells it at £749.99.
- Owners who want consumable costs known up front
- Dyson sells replacement Reuleaux pads, filters, a brush bar with soleplate, and side sweepers, but the UK product page gives no replacement interval or price for any of them.
iRobot Roomba Combo j5+
- Mixed-floor homes expecting carpet to be avoided automatically
- With the mopping bin fitted, the j5+ has no automatic carpet avoidance. Rugs have to be excluded by the owner, either by drawing No Mop Zones in the app or by running only rooms without carpet. A home that needs that judgment made by the machine rather than by the owner is outside this model's design.
- Carpet-primary homes needing intensive mopping
- Mopping bin lacks water heating and pad-lift. Design assumes hard floors with light wet cleaning. Deep carpet cleaning and stubborn stains require manual intervention.
- Owners seeking zero hands-on involvement with mopping
- Bin swaps are required to switch modes. Water tank refill happens manually. Pads are hand-washed weekly. Mopping is not truly autonomous; it is scheduled autonomy.
What stays your job
The upkeep ownership hands back to you, whatever the autonomy level says.
Dyson R2 Nurovi Wash+Dry
- After every use: Dock extracts dirty water, washes the Reuleaux pads in 167°F water and dries them with 113°F air automatically.
- As needed: Empty the dock’s bagless bin, which Dyson rates at up to 90 days on internal test data.
- As needed: Add Dyson 02 Probiotic cleaning solution to the dock if using it for floor and pad washing.
- As needed: Replace the Reuleaux triangle wash pads; Dyson sells spares but publishes no interval or price.
- As needed: Replace the dock and robot filters, sold by Dyson as spares with no published interval.
- As needed: Replace the anti-tangle brush bar with soleplate and the side sweeper when worn.
iRobot Roomba Combo j5+
- Before a run: Fit the Combo bin for vacuum and mop, or the dry bin for vacuum only. The bin sets the mode.
- Before each mopping run: Fill the Combo bin reservoir; empty it before the bin is set aside.
- After every run with the Combo bin: Empty the bin by hand. Automatic Dirt Disposal is disabled while that bin is fitted, so the dock does not evacuate it.
- Weekly: Wash the microfiber pad. iRobot rates the washable pad for about 30 machine washes before replacement.
- Every 2 months: Replace the high-efficiency filter, which is iRobot’s stated interval. The genuine three-pack for Combo and i, e and j series lists at $36.99, about $12 per filter.
- Seasonally: Inspect dock charging contacts, the front caster, wheels and the robot’s sensors.
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.

| iRobot Roomba Combo j5+ | Verified | 9 | Sep 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.
