ComparisonRoborock Qrevo Edge S5A and bObsweep UltraVision

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 bObsweep UltraVision
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. GoodOwners with small homes report the battery covers the whole floor two to three times per charge.
1,500 – 3,000 DependsCoverage is solid, but ~120 min runtime may require recharge between floors on high suction; multi-floor homes may span two charging cycles. DependsbObsweep publishes no runtime figure, so coverage of a mid-size home per charge is not documented.
Over 3,000they differ PoorRuntime inadequate for homes over 3,000 sqft; multi-floor coverage requires multiple recharge breaks and extended session times. DependsNo runtime is published and owners report faster drain on high suction, so large homes may need multiple charges.
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. GoodLiDAR mapping and 8,000 Pa rated suction pick up debris across hard floors, with no carpet limits to manage.
Low / medium pile GoodStandard Qrevo suction rating matches low-pile carpet; manufacturer specs document no performance loss on this surface type. GoodOwners compare its medium and high settings favorably on carpet, at the cost of faster battery drain.
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. DependsbObsweep's manual says the brush is not suited to shag; no figure covers other high-pile carpet.
Mopping needs
Vacuum only GoodStrong vacuum; the mop lifts or detaches when not needed. GoodVacuums first; the mop pad is optional.
Light mopping GoodActive mopping system covers routine floors easily. GoodFlat mop pad handles light, routine wiping of hard floors.
Frequent moppingthey differ GoodPressure or rotating mop with self-wash is built for frequent mopping. DependsA dragged pad freshens floors but lacks the pressure or scrubbing for heavy, 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. GoodMonthly cleaning, weekly brush clearing and hand-washed mop cloths suit an owner willing to do upkeep.
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 dock handles dust for months while the owner handles brushes and mop cloths.
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. DependsOwners report weekly hair clearing and hand-washed mop cloths, so it is not maintenance-free.

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.
