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 Plus 415 Combo IQ Robot Self-Empty XL
Home size
Under 1,500 sqft GoodSlim chassis and AutoWash Dock automation deliver low-maintenance coverage comfortably within homes this size. GoodLiDAR maps small spaces easily; single-floor 800-1,500 sqft optimal for dock placement.
1,500 – 3,000they differ DependsiRobot publishes no per-charge runtime or coverage figures, leaving how far one charge reaches at this size unconfirmed. GoodLiDAR handles 1,500-3,000 sqft effectively; large single-floor layout well-suited.
Over 3,000 DependsNo published runtime, coverage or recharge-resume figures for homes this large; treat coverage here as an open question, not a confirmed limit. DependsCovers 3,000+ sqft but dock placement constraints increase; multiple runs may be needed.
Primary floors
Hard floors Good20,000 Pa suction and DualClean spinning mop pads are documented for hard-floor cleaning in manufacturer and retail listings. GoodDesigned for hard floors; owner reports confirm strong performance and reliable docking.
Low / medium pilethey differ GoodManufacturer and retail specifications document carpet operation alongside hard floors, covering low-pile carpet within that claim. DependsWorks on low-pile but suction efficiency drops; brush design secondary to hard-floor focus.
High pile / shagthey differ Depends20,000 Pa is the lowest suction figure in iRobot's current AutoWash Dock lineup, and no independent test confirms thick-pile performance. 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 AutoWash Dock still empties and self-cleans automatically even for owners willing to handle more maintenance by hand. GoodSelf-empty dock reduces some hands-on time, but filter cleaning and docking resets required 1-2 times monthly.
Empty occasionally GoodAutomated dock upkeep for emptying and mop washing pairs with occasional manual bag and pad replacement, suiting mixed involvement. GoodSelf-empty base and scheduled operation reduce frequent intervention. Filter maintenance every 2-4 runs balances effort.
Set-and-forgetthey differ GoodAutoWash Dock empties, washes and heat-dries mop pads automatically for up to three months of hands-free operation, per manufacturer specs. 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.
