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 Roomba Max 775 Combo bObsweep UltraVision
Home size
Under 1,500 sqft GoodCapable but overkill for apartment-sized spaces; faster-cycling mop-only units suit compact homes better. GoodOwners with small homes report the battery covers the whole floor two to three times per charge.
1,500 – 3,000they differ Good30,000Pa suction completes most 2-floor homes in one run; hot-water mop ideal for kitchen and bathroom flooring. DependsbObsweep publishes no runtime figure, so coverage of a mid-size home per charge is not documented.
Over 3,000they differ GoodExtended runtime and auto-empty dock handle large homes across multiple rooms; multi-floor mapping navigates complex layouts. DependsNo runtime is published and owners report faster drain on high suction, so large homes may need multiple charges.
Primary floors
Hard floors GoodHot-spray mop and motorized wash cycle excel on tile, hardwood, and vinyl; no manual water changes required. GoodLiDAR mapping and 8,000 Pa rated suction pick up debris across hard floors, with no carpet limits to manage.
Low / medium pile Good30,000Pa suction and motorized side brush deliver reliable pickup on low-pile and twist carpet; mop compatibility requires no-mop zones. GoodOwners compare its medium and high settings favorably on carpet, at the cost of faster battery drain.
High pile / shag DependsiRobot flagships document suction loss on shag and high-pile; mop performance on thick carpet may require manual intervention on heavily matted areas. DependsbObsweep's manual says the brush is not suited to shag; no figure covers other high-pile carpet.
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 GoodAuto-empty and hot-water dock reduce daily contact, but weekly water-tank refills, mop-pad swaps, and dock cleaning remain necessary. GoodMonthly cleaning, weekly brush clearing and hand-washed mop cloths suit an owner willing to do upkeep.
Empty occasionally GoodHot-water dock and motorized wash cycle handle most routine maintenance; weekly checks and monthly consumable swaps keep effort moderate. GoodThe dock handles dust for months while the owner handles brushes and mop cloths.
Set-and-forgetthey differ PoorHot-water dock and mop-pad washing require weekly intervention; no truly set-and-forget configuration available for combo units. DependsOwners report weekly hair clearing and hand-washed mop cloths, so it is not maintenance-free.

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.
