Up to three

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.

Fit verdicts by condition for each robot
Condition R2 Nurovi Wash+Dry Roborock S5 Max
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. Good150-min runtime covers under-1,500 sqft in one pass. Suitable for compact homes.
1,500 – 3,000they differ DependsDyson publishes a 90-minute run time but no coverage area per charge, so mid-size homes are unconfirmed. Good150-min runtime handles 1,500-2,500 sqft homes. Multi-floor mapping available via separate dock runs.
Over 3,000 Depends90-minute run time, 6.5-hour charge, and no published recharge-and-resume behavior for a home this size. Depends150-min runtime is borderline for 3,000-4,000 sqft homes. Two cycles per day may be needed on high-debris homes.
Primary floors
Hard floors GoodTwin-capture brush bar and suction pick up debris while the rotating pads wash hard floors in the same run. GoodSingle retractable mop pad handles hard floors well. 10,000 Pa suction adequate for hard-surface debris.
Low / medium pilethey differ DependsUltrasonic sensor detects carpet and adjusts suction; Dyson publishes no mop-lift figure for crossing rugs. GoodMop pad is wide and handles low-pile carpet. Performance trails rotating dual-pad systems but is functional.
High pile / shagthey differ DependsNo independent deep-pile test published, and Dyson does not state whether the wash pads lift clear of pile. PoorSingle static pad is not designed for high-pile or shag carpet. Manufacturer documentation does not recommend.
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 dust-bin empties and monthly LiDAR cleaning fit hands-on routines. Low-complexity dock requires no special skills.
Empty occasionally GoodBin emptying every few months and occasional spare-part swaps are the main owner tasks Dyson describes. GoodAuto-dock handles dust and water. Monthly mop pad and brush maintenance are the main hands-on tasks.
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 empties and monthly lens cleaning contradict hands-off operation.

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.
