ComparisonROIDMI EVA and iRobot Roomba Plus 678 Combo

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 ROIDMI EVA Roomba Plus 678 Combo
Home size
Under 1,500 sqft GoodA 220-minute runtime clears space this size before the reviewed dustbin capacity issue becomes a factor. GoodRecharge-and-resume and retained LiDAR mapping comfortably cover a compact single-level home in one scheduled run.
1,500 – 3,000they differ DependsA 220-minute runtime may need a recharge cycle here, and an independent review found mop-pad drying ineffective afterward. GoodSystematic LiDAR mapping and recharge-and-resume are built for this range; typical single-level layouts complete in one scheduled run.
Over 3,000they differ PoorAn independent review found the bin can't finish a full-floor clean this large without manual emptying partway through. DependsIndependent multi-level or large-home coverage testing does not yet exist for this model; recharge-and-resume adds passes rather than eliminating them.
Primary floors
Hard floors GoodDual spinning mop pads apply pressure-controlled downforce for hard-floor cleaning, per the manufacturer's design. GoodThe PowerSpin roller and LiDAR navigation are built around hard-floor vacuum-plus-mop runs.
Low / medium pile GoodMop pads lift automatically on carpet, and the manufacturer states 4 suction levels for varying floor types. GoodThe roller auto-lifts on low-pile carpet detection; suction performance on carpet is not independently benchmarked.
High pile / shag DependsNo independent test of high-pile performance was found; only 4 suction levels and automatic pad lift are documented. DependsNo independent suction or high-pile test results are documented for this model, and rated suction trails the Max-tier sibling.
Mopping needs
Vacuum only GoodStrong vacuum; the mop lifts or detaches when not needed. GoodStrong vacuum; the mop lifts or detaches when not needed.
Light mopping GoodActive mopping system covers routine floors easily. GoodActive mopping system covers routine floors easily.
Frequent mopping GoodPressure or rotating mop with self-wash is built for frequent mopping. GoodPressure or rotating mop with self-wash is built for frequent mopping.
You want to…
Empty bin myself GoodYou'll already check the bin regularly, sidestepping the independent review's finding that the dock's bin fills too fast. GoodThe dock automates roller washing and bin emptying, but a hands-on reader can still top off concentrate and run manual clean cycles.
Empty occasionallythey differ DependsThe self-empty dock reduces bin duties, but expect occasional manual mop-pad handling since drying reportedly leaves pads damp. GoodThe AutoWash dock's self-wash and self-empty cycles handle most routine upkeep between periodic concentrate refills and bag swaps.
Set-and-forgetthey differ PoorAn independent review found the bin fills too fast and mop pads stay damp over 12 hours, undermining true set-and-forget use. DependsThe dock automates washing and emptying, but the concentrate reservoir and self-empty bag still need periodic manual refills, so it is not fully hands-off.

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.
