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 eufy E20 Roomba Plus 415 Combo
Home size
Under 1,500 sqft GoodCapable but exceeds compact-home needs. Single-charge coverage matches smaller spaces; modular appeal less critical. GoodSlim chassis and AutoWash Dock automation deliver low-maintenance coverage comfortably within homes this size.
1,500 – 3,000they differ GoodOptimal range for E20. Full coverage in one charge; multi-story flexibility rewards detachable stick design. DependsiRobot publishes no per-charge runtime or coverage figures, leaving how far one charge reaches at this size unconfirmed.
Over 3,000 DependsLarge homes may need two charging cycles. Multi-module swaps help with second-floor; total runtime is battery-limited. DependsNo published runtime, coverage or recharge-resume figures for homes this large; treat coverage here as an open question, not a confirmed limit.
Primary floors
Hard floors GoodExpert Reviews found it did a great job on flour and pet hair on hard floors, its strongest documented surface. Good20,000 Pa suction and DualClean spinning mop pads are documented for hard-floor cleaning in manufacturer and retail listings.
Low / medium pilethey differ DependsWirecutter measured visible glitter left behind on carpet even in Turbo mode, and Expert Reviews found a smudgy flour residue too. GoodManufacturer and retail specifications document carpet operation alongside hard floors, covering low-pile carpet within that claim.
High pile / shag DependsNo deep-pile test exists; 8,000 Pa suction already left visible residue on standard carpet in independent reviews, before adding thicker pile. Depends20,000 Pa is the lowest suction figure in iRobot's current AutoWash Dock lineup, and no independent test confirms thick-pile performance.
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 GoodThe bin empties by hand after every run already, about five minutes' work, matching this preference directly. GoodThe AutoWash Dock still empties and self-cleans automatically even for owners willing to handle more maintenance by hand.
Empty occasionallythey differ DependsThe bin is emptied after every run, not occasionally; there's no auto-empty dock to stretch that interval out. GoodAutomated dock upkeep for emptying and mop washing pairs with occasional manual bag and pad replacement, suiting mixed involvement.
Set-and-forgetthey differ PoorThere's no auto-empty dock, and swapping the one motorized core between robot, stick, and handheld is manual by design. GoodAutoWash Dock empties, washes and heat-dries mop pads automatically for up to three months of hands-free operation, per manufacturer specs.

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.
