ComparisonDyson R2 Nurovi Wash+Dry and Shark IQ Robot Self-Empty XL

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 IQ Robot Self-Empty XL
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. GoodLiDAR maps small spaces easily; single-floor 800-1,500 sqft optimal for dock placement.
1,500 – 3,000they differ DependsDyson publishes a 90-minute run time but no coverage area per charge, so mid-size homes are unconfirmed. GoodLiDAR handles 1,500-3,000 sqft effectively; large single-floor layout well-suited.
Over 3,000 Depends90-minute run time, 6.5-hour charge, and no published recharge-and-resume behavior for a home this size. DependsCovers 3,000+ sqft but dock placement constraints increase; multiple runs may be needed.
Primary floors
Hard floors GoodTwin-capture brush bar and suction pick up debris while the rotating pads wash hard floors in the same run. GoodDesigned for hard floors; owner reports confirm strong performance and reliable docking.
Low / medium pile DependsUltrasonic sensor detects carpet and adjusts suction; Dyson publishes no mop-lift figure for crossing rugs. DependsWorks on low-pile but suction efficiency drops; brush design secondary to hard-floor focus.
High pile / shagthey differ DependsNo independent deep-pile test published, and Dyson does not state whether the wash pads lift clear of pile. PoorOwner reports document suction loss and frequent brush tangling on high-pile and shag carpet.
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.
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. GoodSelf-empty dock reduces some hands-on time, but filter cleaning and docking resets required 1-2 times monthly.
Empty occasionally GoodBin emptying every few months and occasional spare-part swaps are the main owner tasks Dyson describes. GoodSelf-empty base and scheduled operation reduce frequent intervention. Filter maintenance every 2-4 runs balances effort.
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. PoorFilter clogging and occasional docking misalignment prevent true hands-off operation on pet homes.

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.
