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 515 Combo IQ Robot Self-Empty XL
Home size
Under 1,500 sqft GoodA 295-minute, 2,000 sq ft rating per charge covers a home this size in one run. GoodLiDAR maps small spaces easily; single-floor 800-1,500 sqft optimal for dock placement.
1,500 – 3,000 GoodiRobot rates a charge at 2,000 sq ft, covering most homes in this range in one run. GoodLiDAR handles 1,500-3,000 sqft effectively; large single-floor layout well-suited.
Over 3,000 DependsRated 2,000 sq ft per charge, and recharge-and-resume behavior is not documented for this model. DependsCovers 3,000+ sqft but dock placement constraints increase; multiple runs may be needed.
Primary floors
Hard floors GoodSpinning DualClean pads at 180 RPM with SmartScrub target dried spills on sealed hard floors. GoodDesigned for hard floors; owner reports confirm strong performance and reliable docking.
Low / medium pilethey differ GoodCarpet detection lifts the pads 10 mm before crossing rugs, per iRobot. DependsWorks on low-pile but suction efficiency drops; brush design secondary to hard-floor focus.
High pile / shagthey differ DependsA 10 mm pad lift may not clear dense pile, and no independent carpet test exists for this model. 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 GoodHands-on upkeep is light; the dock handles debris, water and pad washing. GoodSelf-empty dock reduces some hands-on time, but filter cleaning and docking resets required 1-2 times monthly.
Empty occasionally GoodOwner tasks come down to brush checks, adding solution and a tank service every few months. GoodSelf-empty base and scheduled operation reduce frequent intervention. Filter maintenance every 2-4 runs balances effort.
Set-and-forgetthey differ GoodiRobot rates the dock for up to three months without emptying bins or handling water. 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.
