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.

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 iRobot Roomba Max 715 Dyson R1 Nurovi Dry
Home size
Under 1,500 sqft GoodCapable but self-empty dock is overkill for compact homes; smaller J7 or budget model sufficient. GoodA 120-minute run and saved LiDAR maps cover a compact home comfortably in one pass.
1,500 – 3,000they differ GoodFlagship positioning; covers 1500-3000 sqft in 1-2 scheduled runs with dock self-empty. 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 Depends120-min runtime may require two passes on 3000+ sqft homes without breaks; schedule multiple runs. 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 GoodSealed hard-floor performance strong; pre-filter and cliff sensors handle transitions well. GoodBuilt around hard floors: 21,000 Pa rated suction plus an ultrasonic sensor that separates hard floor from carpet.
Low / medium pile GoodHistorical j-series strength; 8500 Pa suction covers low-pile and standard carpet reliably. 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 iRobot models document suction loss and motor strain on shag and high-pile carpet. 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

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.
