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 | eufy E20 | R2 Nurovi Wash+Dry |
|---|---|---|
| Home size | ||
| Under 1,500 sqft | GoodCapable but exceeds compact-home needs. Single-charge coverage matches smaller spaces; modular appeal less critical. | GoodLiDAR mapping and a 90-minute maximum run time, per Dyson, cover a compact floor plan in one charge. |
| 1,500 – 3,000they differ | GoodOptimal range for E20. Full coverage in one charge; multi-story flexibility rewards detachable stick design. | DependsDyson publishes a 90-minute run time but no coverage area per charge, so mid-size homes are unconfirmed. |
| Over 3,000 | DependsLarge homes may need two charging cycles. Multi-module swaps help with second-floor; total runtime is battery-limited. | Depends90-minute run time, 6.5-hour charge, and no published recharge-and-resume behavior for a home this size. |
| Primary floors | ||
| Hard floors | GoodExpert Reviews found it did a great job on flour and pet hair on hard floors, its strongest documented surface. | GoodTwin-capture brush bar and suction pick up debris while the rotating pads wash hard floors in the same run. |
| Low / medium pile | DependsWirecutter measured visible glitter left behind on carpet even in Turbo mode, and Expert Reviews found a smudgy flour residue too. | DependsUltrasonic sensor detects carpet and adjusts suction; Dyson publishes no mop-lift figure for crossing rugs. |
| High pile / shag | DependsNo deep-pile test exists; 8,000 Pa suction already left visible residue on standard carpet in independent reviews, before adding thicker pile. | DependsNo independent deep-pile test published, and Dyson does not state whether the wash pads lift clear of pile. |
| Mopping needs | ||
| Vacuum only | GoodVacuum-only robot — matches a vacuum-only need. | GoodStrong vacuum; the mop lifts or detaches when not needed. |
| Light moppingthey differ | PoorThis model has no mopping function. | GoodActive mopping system covers routine floors easily. |
| Frequent moppingthey differ | PoorNo mop at all; choose a vacuum-and-mop robot instead. | GoodPressure or rotating mop with self-wash is built for frequent mopping. |
| You want to… | ||
| Empty bin myself | GoodThe bin empties by hand after every run already, about five minutes' work, matching this preference directly. | GoodThe dock empties the bin and washes the pads, so hands-on upkeep is lighter than this option allows. |
| Empty occasionallythey differ | DependsThe bin is emptied after every run, not occasionally; there's no auto-empty dock to stretch that interval out. | GoodBin emptying every few months and occasional spare-part swaps are the main owner tasks Dyson describes. |
| Set-and-forgetthey differ | PoorThere's no auto-empty dock, and swapping the one motorized core between robot, stick, and handheld is manual by design. | GoodDock self-empties, washes pads at 167°F, dries them at 113°F and refills; bin rated up to 90 days. |
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.

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.
eufy E20
Modular swaps buy multi-tool reach but cost convenience: the one battery lives in the core, so the robot cannot run while the core is in the stick or handheld body, and every manual session spends charge a scheduled clean would have used.
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.
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.
eufy E20
- Homes requiring set-and-forget autonomy without docking rituals
- Modular swaps (vacuum to stick to handheld) require owner attention. If your priority is schedule-and-forget operation, the routine dock cycle adds friction.
- Owners who need wet cleaning
- The E20 does not mop. eufy points shoppers wanting mopping to the E28; a vacuum-mop combination is a different machine, not a configuration of this one.
- Tight budgets seeking entry-level autonomy without premium modular design
- The detachable-core design targets mid-to-flagship pricing. Single-unit vacuums at lower MSRPs deliver comparable Level III navigation for less.
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.
What stays your job
The upkeep ownership hands back to you, whatever the autonomy level says.
eufy E20
- Weekly: Empty dustbin after each run (~5 min).
- Weekly: Rinse filter; replace monthly (~$8-12/replacement).
- Monthly: Clean brush and side brush; trim tangled fibers.
- Every 3-6 months: Replace side brush (~$12-18/pair).
- Monthly: Wipe dock charging pins to prevent oxidation.
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.
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 |

| Dyson R2 Nurovi Wash+Dry | Verified | 8 | 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.
