Compare Roborock S8 MaxV Ultra Robot Vacuum and Mop vs Roborock Qrevo Edge Robot Vacuum and Mop

Floorhead design had a notable flaw in PCMag's mopping stress test because brush lifting did not work effectively.

The floorhead/brush design is praised for sweeping debris effectively across hard floors and carpet.

The cleaning-solution system was praised for convenience and for improving mop performance.

The liquid system is a drawback for users wanting auto-solution dosing because detergent must be handled manually.

Auto-empty reliability was a weak spot in one comparative test, where debris remained in the robot after emptying.

Docking and auto-empty reliability is a major plus in the flagship-style dock setup.

Hair-wrap resistance was the biggest cleaning weakness, with one test stopping the robot and another Roborock comparison ranking it poorly, despite PCMag's better experience.

Hair-wrap resistance is a standout strength, with zero or near-zero tangles repeatedly reported.

Hard-floor hair pickup was positive in the pet-home review, where the S8 avoided clump-leaving issues seen on another robot.

Hard-floor hair pickup is imperfect in one home review, which noted occasional pet fluff left behind.

The dock heating systems were praised through hot-air drying that helped prevent musty odors, supporting a high heating-element score.

The heating system works enough to produce hot water, but one reviewer was unsure it reached the advertised temperature.

Mop lifting was a standout strength, especially in the comparative test where it kept high-pile carpet dry.

The mop lift helps, but it may not keep very high-pile carpets completely dry.

Privacy controls were praised for onboard processing, disabled-by-default remote video, camera-password controls, and audible remote-view alerts.

Privacy is a tradeoff: the camera adds features, while the non-camera S5A is framed as better for privacy-concerned buyers.

Runtime was acceptable but not exceptional in PCMag's test, ending at 101 minutes before recharge.

Runtime is strong overall, with high efficiency and long battery life noted for larger spaces.

Large hard-floor debris handling was mixed, with one broad test positive but PCMag reporting rice and sand scatter.

Large hard-floor debris intake is strong in controlled debris pickup testing.

Design impressions were strongly positive, with reviewers praising the aesthetics of both the robot and dock.

Aesthetic feedback is lukewarm: the design is acceptable but visually robot-like in a corner.

Heavy-duty suitability was favorable where reviewers cited strong combined vacuuming and mopping performance.

Heavy-duty suitability is limited because one reviewer says it does not replace a full vacuum.

Value was divisive and often price-sensitive: several reviewers criticized the flagship price, while value was defended only when performance and convenience justified it.

Value opinions are split: reviewers see strong performance and savings versus some alternatives, but several still flag the high purchase price.

Emptying and mess control was mixed: a comparative test left debris in the bin, but the bagged self-emptying system was praised for convenience.

Emptying and mess control are excellent for the user, with the dock reducing mop rinsing and dustbin emptying.

The dust bag system was viewed as a major convenience, with self-emptying described as the preferred approach.

The dust bag/bin system reduces manual emptying, but one reviewer still notes the bag must be changed periodically.

Reviewers praised the jump in suction and premium cleaning power, with especially strong language from long-term and detailed-use reviews.

Review evidence is mixed: one comparison says an Ecovacs rival measured higher, while another reviewer found little practical suction difference versus the Edge S5A.

Battery evidence was middling: one test reached 101 minutes before returning to charge, behind some high-end competitors.

Battery evidence is mixed-positive: official and test runtime look strong, but a thorough clean could require a mid-run charge.

Build/design detail was praised, with one reviewer saying the small details felt carefully considered.

Build quality gets a positive stress-test signal because the mop pad did not fall off when the robot struggled around furniture.

Debris-prevention evidence was positive but qualified: it could keep working through small foreign objects, though rollers still sometimes needed clearing.

Clogging prevention is a major strength, especially for hair, with one reviewer reporting no clogging issues.

Area-rug handling was strong in reviews that praised carpet/rug settings and hard-floor/rug cleaning behavior.

Rug handling is generally good for rugs and door frames, but high-pile carpets can still get wet.

Large-debris handling was positive in Lifehacker's experience because the robot could keep working after encountering foreign objects.

Large debris handling is positive, with breadcrumbs, nuts, and other test debris cleaned up well.

Fine-dust hard-floor pickup was inconsistent: one test was decent, PCMag found poor relative performance, and Lifehacker was impressed in home use.

Fine-dust hard-floor pickup is generally strong, though one home test still found missed dust patches.

Noise feedback was acceptable but not silent: one Roborock comparison ranked it well, while another said it was not loud but disruptive for calls.

Noise evidence is limited but positive, with a reviewer listing quiet operation among the pros.

Medium/generic carpet pickup was mixed-to-good: comparative tests showed good but not class-leading pickup, including flour/sand limitations.

Medium-pile carpet deep cleaning performed much better than average in testing.

Controls and UI were broadly liked for intuitive apps and rich options, though Rocky and remote video had wording and quality limits.

Controls earn praise for granular water and cleaning settings, especially the wide water-level range.

Carpet pet-hair pickup was strong in the comparative test, leaving only a single dense clump.

Carpet hair pickup is above average in one test but below a named competitor in another comparison.

Obstacle avoidance was sharply split, ranging from flawless and best-in-test to PCMag's repeated obstacle impacts.

Obstacle avoidance is the clearest weakness: it is better than having no sensors, but cables, cords, and small objects remain trouble spots.

Corner cleaning was largely positive thanks to edge-reaching arms and carpet-corner performance.

Corner cleaning is mostly strong thanks to extending brush and mop hardware, though one home review still found tight corners missed.

Comparative performance was mixed: it topped one 2024 scorecard, but another Roborock-only test favored cheaper models overall.

Comparative evidence favors the Edge in several matchups, especially against S5A navigation and Curv value/water-use tradeoffs.

High-pile/deep-pile carpet pickup was praised strongly in Lifehacker's home testing.

High-pile carpet pickup looked strong in one test area, though other carpet-related evidence is more about wetting and thresholds.

Dried-on stain evidence was strong in Lifehacker's use, though stubborn stains could still require an extra pass.

Dried stain removal is above average overall, but stubborn stains can still take multiple passes.

Hair-removal channel behavior improved over a prior S8 but still sometimes required roller clearing.

Hair-removal channeling works, but one reviewer wished the robot fully sucked hair away instead of requiring manual removal.

Innovation evidence was positive where the extending edge arms were described as a major leap forward for reaching walls and toe kicks.

Innovation is praised around the side brush, edge coverage, and newer feature set, though some AI functions are seen as less essential.

Apple Home/Matter support was described as a positive step, though the Roborock app remained the deeper control center.

The Roborock app is described as granular and frequently updated, supporting longer-term feature usefulness.

Under-furniture pickup was praised where the Flexi-arms reached under toe kicks and nearby items that older edge brushes missed.

Under-furniture pickup is praised because it reached hard-to-access areas under and behind furniture.

Mopping performance was highly mixed across tests, from weak dried-mud/jelly results to excellent everyday and stubborn-stain performance.

Mopping performance is broadly praised for everyday cleaning and visible results, with smearing on big messes as the main caveat.

Hard-floor edge/baseboard cleaning was split: some reviewers praised edge reach, while one ketchup test left cabinet-edge residue.

Edge and baseboard cleaning are a standout strength, with multiple reviewers praising close edge reach from the side brush and mop.

Overall cleaning convenience was very strong, with reviewers emphasizing reduced hands-on floor cleaning.

Cleaning convenience is one of the biggest benefits, with reviewers saying it saves time and reduces manual cleaning.

Self-cleaning performance was one of the strongest areas, with praise for hot-water washing, auto detergent, dock cleaning, and mop care.

Self-cleaning is consistently praised, with the dock, tray, and mop-pad washing/drying making upkeep easier.

Value-for-money was mixed-to-positive: one guide called it exceptional, while another saw the price as fair only if affordable.

Value-for-money is strong when priced near the Curv or discounted, because performance remains close to the flagship alternative.

Ease of use was strongly positive, with owner-style reviewers calling it a pleasure and praising the app.

Ease of use is strong, especially through the app and remote control.

Setup was consistently easy, with reviewers describing app pairing, assembly, and first setup as straightforward.

Setup is praised as very simple in hands-on use.

Pet-related evidence was mostly favorable: reviewers liked pet-finding, pet-waste options, and pet-hair pickup, though not every pet interaction was perfect.

Pet-oriented evidence is positive, with reviewers calling it suitable for hairy rugs, dogs, and pet snapshots, though not every pet-hair spot was perfect.

Stuck resistance was mixed: PCMag said the second unit did not get stuck, but obstacle struggles still remained.

Stuck resistance is mixed: one review says it did not get stuck, while another showed a difficult furniture escape.

Mapping and pathing were generally excellent, with app maps, room editing, and self-location all praised.

Mapping and navigation are consistently praised as accurate, efficient, and smart across several reviews.

Smart features and automation were a highlight, including top feature scoring, integrations, app reliability, and rich customization.

The smart app and automation stack is a major strength, with reviewers praising mapping, remote control, AI features, and feature depth.

Residue control was mixed: one comparative mop test left sticky floors, while PCMag found only limited jelly spread.

Streaking and residue are a repeated concern due to higher water use, smearing on big messes, and residue in crevices.

Overall opinion ranged from cautious to glowing, but most reviews treated it as a highly capable flagship with price and performance tradeoffs.

Overall opinion is strongly positive across reviews, with repeated recommendations and top-pick language despite caveats.

The included command card was described positively as a useful reference for Rocky voice commands.

Adaptive chassis lift is useful for thresholds and obstacles, though one reviewer found it fell short of the advertised maximum threshold.

Cord management was praised because the dock provided a neat place to wrap the cord.

Crevice and groove pickup is only fair, with residue left in tile cracks and crevices after cleaning.

Dirty-water sensing and remopping are helpful when they trigger, but one review found automatic remopping failed on test stains.

Dock noise was a drawback because drying noise was noticeable and louder than one household wanted nearby.

Edge-following accuracy was only moderate: it avoided wall impacts well but still created baseboard brush marks.

Dust containment was praised because the self-emptying bag seals dust after removal, useful for sensitive sinuses.

Fresh spill handling is acceptable but not instant, with liquid spills needing more than one pass.

Headlights were noted as useful during dark-area cleaning and navigation.

Low-profile design was limited by size; it could not fit between chair legs that a smaller robot could.

Maintenance requirements were favorable overall, with long water-change intervals and less intervention than many robots.

Maneuverability is mixed: the robot kept trying and eventually escaped, but tricky furniture caused a prolonged struggle.

Odor control was praised through detergent dispensing and hot-air drying that reduce bacterial growth and musty smells.

Consumable cost evidence was mildly positive because six dust bags per year was not seen as excessive.

Longevity evidence was favorable from an eight-month user who still repeatedly recommended the robot.

Scratch resistance was a concern in one comparative test because the side brushes left swirl marks on white baseboards.

Small-space suitability was weak because its size kept it from fitting between dining-chair legs that a smaller competitor could handle.

Reliability evidence was strong in owner-style reviews, including repeated recommendation and confidence based on Roborock experience.

Surface safety evidence was mixed: PCMag saw no scratching on hard floors, but another test reported side-brush swirl marks on white baseboards.

Tool-change simplicity had a notable drawback because PCMag listed the non-detachable mop cloth mount as a con.

Versatility evidence was favorable because reviewers highlighted the broad configurability of cleaning modes and zones.

The clean-water tank was easy to remove and handle, supporting a positive water-tank usability score.

Weight feedback was neutral-to-positive: the robot felt substantial but not overly heavy in handling.
