ComparisonRoborock Qrevo Edge S5A 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 Qrevo Edge S5A Roomba Plus 678 Combo
Home size
Under 1,500 sqft GoodRuntime and coverage suit compact homes; single charge handles most 1,500 sqft homes in one pass on low suction. GoodRecharge-and-resume and retained LiDAR mapping comfortably cover a compact single-level home in one scheduled run.
1,500 – 3,000they differ DependsCoverage is solid, but ~120 min runtime may require recharge between floors on high suction; multi-floor homes may span two charging cycles. 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 PoorRuntime inadequate for homes over 3,000 sqft; multi-floor coverage requires multiple recharge breaks and extended session times. 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 Good18,500 Pa suction on hard floors is efficient; edge-cleaning side brush performs well on transitions between tile and carpet. GoodThe PowerSpin roller and LiDAR navigation are built around hard-floor vacuum-plus-mop runs.
Low / medium pile GoodStandard Qrevo suction rating matches low-pile carpet; manufacturer specs document no performance loss on this surface type. GoodThe roller auto-lifts on low-pile carpet detection; suction performance on carpet is not independently benchmarked.
High pile / shagthey differ PoorOwner reports document suction loss on shag and high-pile carpets; 18,500 Pa sits below the threshold needed for plush surfaces. 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 GoodMonthly dust-bag swap and weekly brush cleaning match owners who prefer active maintenance over set-and-forget automation. 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 DependsRequires monthly intervention for dust bags, but no mop-wash cycle or auto-dry. Less frequent than manual-vacuum, more hands-on than flagship auto-empty. 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 PoorMonthly dust-bag replacement and quarterly deep cleans are unavoidable; dock has no auto-empty or mop-wash to reduce owner effort. 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.
