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 bObsweep UltraVision Roomba Plus 505 Combo
Home size
Under 1,500 sqft GoodOwners with small homes report the battery covers the whole floor two to three times per charge. GoodFully capable but premium features exceed what compact homes typically need; 405 offers same core function at lower cost.
1,500 – 3,000they differ DependsbObsweep publishes no runtime figure, so coverage of a mid-size home per charge is not documented. Good90-minute runtime with obstacle avoidance handles multi-room layouts in this range well.
Over 3,000 DependsNo runtime is published and owners report faster drain on high suction, so large homes may need multiple charges. DependsRuntime caps at 90 min; will require multiple sessions per day. Premium features not offset by size limitation.
Primary floors
Hard floors GoodLiDAR mapping and 8,000 Pa rated suction pick up debris across hard floors, with no carpet limits to manage. GoodMopping optimized for sealed tile, wood, and stone; heated drying ideal for these surfaces.
Low / medium pile GoodOwners compare its medium and high settings favorably on carpet, at the cost of faster battery drain. GoodVacuum and mop both handle low-pile well; obstacle avoidance improves edge detection on carpet boundaries.
High pile / shagthey differ DependsbObsweep's manual says the brush is not suited to shag; no figure covers other high-pile carpet. PoorOwner reports document suction loss and pad drag on shag and high-pile carpet; not recommended for deep-pile homes.
Mopping needs
Vacuum only GoodVacuums first; the mop pad is optional. GoodStrong vacuum; the mop lifts or detaches when not needed.
Light mopping GoodFlat mop pad handles light, routine wiping of hard floors. GoodActive mopping system covers routine floors easily.
Frequent moppingthey differ DependsA dragged pad freshens floors but lacks the pressure or scrubbing for heavy, frequent mopping. GoodPressure or rotating mop with self-wash is built for frequent mopping.
You want to…
Empty bin myself GoodMonthly cleaning, weekly brush clearing and hand-washed mop cloths suit an owner willing to do upkeep. GoodWeekly heating-chamber checks and thermostat monitoring align with hands-on ownership.
Empty occasionally GoodThe dock handles dust for months while the owner handles brushes and mop cloths. GoodHeated dock automates mop drying, but weekly water checks and monthly dock maintenance required.
Set-and-forget DependsOwners report weekly hair clearing and hand-washed mop cloths, so it is not maintenance-free. DependsCapable but heated dock adds monthly thermostat inspection; not a true set-and-forget system despite automation.

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.
