ComparisonDyson 360 Vis Nav and iRobot Roomba Max 875 Combo

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 Dyson 360 Vis Nav Roomba Max 875 Combo
Home size
Under 1,500 sqft GoodCapable but exceeds typical need; a mid-tier LiDAR vacuum covers compact homes at half the price. Good35,000 Pa handles compact layouts in a single scheduled run; the dock reduces daily contact regardless of home size.
1,500 – 3,000 GoodSingle-session coverage maps most homes in this range on standard mode. Multi-story layouts require two units. GoodAuto-empty AllergenLock bag and full-pass suction cover mid-size multi-room layouts without documented mid-cycle intervention.
Over 3,000 Depends65-minute runtime limits single-charge coverage; recharge-and-resume extends sessions but lengthens total cleaning time. Multi-story homes also require carrying the robot between floors. DependsiRobot has not published a per-charge coverage area for this model; larger layouts may need an undocumented recharge-and-resume cycle.
Primary floors
Hard floors GoodVision mapping and obstacle avoidance perform well on hard floors; cleaning power is well-suited for sealed wood and tile. GoodPowerSpin Max roller with 18N applied pressure and 300 rpm scrubbing targets sealed hard floors directly.
Low / medium pile GoodHigh suction and the full-width brush bar perform consistently on low-pile carpet. Typical maintenance is weekly dustbin emptying. GoodSealForce lowers a skirt around the cleaning head on carpet detection, directing more airflow into low-pile fibers.
High pile / shagthey differ PoorOwner reports document marked suction loss on shag and high-pile carpet despite peak power. Not recommended for thick-pile environments. DependsiRobot claims up to 3x deeper carpet cleaning with SealForce, but independent testing on dense high-pile is not yet available.
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 GoodManual dustbin emptying every 1-3 runs suits owners comfortable with frequent maintenance. Weekly filter care is standard. GoodDock automation (auto-empty, hot-water roller wash, heated-air dry) exceeds a hands-on tolerance; there is simply less to do by hand.
Empty occasionallythey differ DependsLacks self-emptying dock; suits mixed tolerance only if owners accept weekly-to-daily dustbin swaps depending on shedding rate. GoodWeekly tank refill and periodic bag changes fit a mixed hands-on and hands-off routine without daily contact.
Set-and-forgetthey differ PoorNo self-emptying base. Manual dustbin handling every 1-3 runs conflicts with true hands-off operation goals. DependsThe dock still needs a weekly clean-water refill and a debris bag swap; iRobot has not documented a fully unattended cycle beyond that.

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.
