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

Odor control was a clear weakness when the robot got stuck with dirty mops and left a bad smell.

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

High-pile carpet suitability was limited, with a reviewer recommending a different robot for deeper carpets.

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

Carpet hair pickup was weak in one review, which said the robot barely disturbed matted animal hair in the rug.

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

Low-profile design was praised for fitting under furniture and being among the flattest LiDAR robots reviewed.

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

Small-space suitability was strong thanks to good under-furniture and tight-space navigation.

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

Value was one of the strongest themes: reviewers repeatedly praised the sale price and overall value, while warning that the Qrevo S makes less sense at higher pricing.

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

Heavy-duty cleaning was limited; reviewers said huge muddy messes or visible mud stains still required manual follow-up.

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

Scratch resistance received positive support from the ScratchSafe wheel outcome described in the review.

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

Docking and auto-empty performance was positive where tested, with the multifunction dock called a huge pro and one reviewer saying auto-empty worked.

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

Area-rug handling was mixed: one reviewer’s rug became pristine, but others reported mop pads catching on rug edges or poor attention to rug hair.

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

Edge and baseboard cleaning was one of the repeated limitations, with reviewers noting missed toe spaces, wall edges and clear lines left behind.

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

Battery and charging feedback was positive, with above-average efficiency and reviewers calling battery life long or excellent.

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

Liquid control was mixed: water-flow adjustment was praised, but the lack of detergent support was a limitation.

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

Warm-air drying was viewed as helpful but not decisive; one reviewer said the warm-air advantage did not matter much in practice.

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

Runtime was strong, with reviewers noting leftover power after cleaning and excellent battery life.

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

Stuck resistance was a weakness in one long-term review, where the robot became wedged and needed human intervention.

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

Medium/carpet pickup was a weak point in one review, which reported performance dropping when vacuuming carpets.

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

Hard-floor fine-dust pickup was consistently strong, with praise for hard-floor debris pickup and tests leaving no visible dust in some reviews.

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

Self-cleaning was praised for reducing maintenance burden and making the robot low-maintenance, though the dock does not include every higher-end self-cleaning feature.

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

The bag/bin system was viewed as low-hassle, with the dock bag described as large enough to hold dirt for weeks.

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

Dock noise was mixed: one reviewer called dust emptying loud but quick, while another found dock emptying clearly not quiet.

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

Hard-floor hair pickup was praised in a narrative review where dog hair was pulled into the robot’s path and sucked up effectively.

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

Residue control was positive in one test where flour was picked up without spreading white debris around the house.

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

Support was described positively in outcome and tone, though the supporting review also noted the replacement process took time.

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

Obstacle avoidance was the most divided attribute: some reviews called it bad or cable-prone, while others reported excellent avoidance in their own tests.

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

Reviewers liked the clean, minimal look and finish, with praise for the high-quality finish and how it fit into home decor.

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

Emptying and mess control were praised as low-effort, with one reviewer barely having to lift a finger for cleaning maintenance.

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

The mop-lifting system was widely valued for mixed flooring and short-pile carpet protection, though rug transitions could still expose blind spots.

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

The app and controls were praised as premium, stable, detailed and easy to work with compared with competitors.

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

Reviewers generally found suction strong for everyday debris and smooth floors, with above-average airflow and praise for crumbs, pet hair and hard-floor pickup; carpet deep cleaning was treated more cautiously.

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

Large debris handling was good overall, especially for crumbs and cereal, though one comparison test still found a few corn flakes left behind.

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

Comparative performance was favorable overall, with the Qrevo S beating or matching more expensive models in some tests and being called the best mid-range robot tested by one source.

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

The included setup pieces and instructions were viewed positively, with the instructions described as useful.

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

Build quality received positive feedback through praise for the high-quality finish of the robot and docking station.

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

Edge-following accuracy was a limitation in one test where the robot left a visible line after multiple passes.

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

Floorhead design was questioned on rugs because one reviewer doubted how well the rubber roller could lift material from fabric floors.

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

The Qrevo S was viewed as unusually advanced for its price, especially for control and customization that reviewers associated with pricier robots.

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

Large debris handling was praised by one reviewer who said the robot made light work of small and large crumbs.

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

Ownership costs looked favorable in one Roborock comparison, where the Qrevo S led on combined filter and dust-bag cost.

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

Tool-change feedback was mixed-negative because the mop heads were easy to snap on but could also snap off their mounts during use.

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

Under-furniture pickup was a strength, with reviewers praising its ability to get under sofas, bar carts and other tight furniture areas.

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

Value-for-money was described as first-class in the price-to-performance sense.

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

Versatility was praised by a reviewer who used it upstairs, downstairs, on hard floors and on soft surfaces without issues.

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

The water-tank maintenance burden was viewed positively by one reviewer who said the dirty tank only needed emptying every seven weeks.

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

Weight was a minor drawback for one reviewer who found it a little heavy, though not a major day-to-day issue.

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

Hair-wrap feedback was mixed: one review praised the rubber brush for avoiding tangled hair, while others found hair wrapped around the roller or ranked the Qrevo S poorly in hair-tangle testing.

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.

Mapping and pathing were widely praised as efficient, accurate and better than competing mid-range robots, with strong feedback on straight-line cleaning and quick navigation.

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

Corner cleaning received positive support in one home review that praised pickup in tight kitchen corners.

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

Mopping performance was a major strength on normal hard-floor messes and many dried stains, though some tough mud or one-pass stain tests remained challenging.

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

Ease of use was strong, with reviewers praising broad household suitability and simple press-and-go operation.

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

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

Overall opinion was strongly favorable across reviewers, who called it a top mid-range pick, excellent value, impressive and a product they could recommend with price caveats.

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

Dried-on stain performance was generally strong, with multiple reviewers reporting above-average scores or successful removal of jelly, coffee and other dried messes, though tougher stains could remain.

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

Hair-removal maintenance was positive because the roller design made wrapped hair easy to remove.

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

Pet fur was specifically reported as not posing an issue, making the robot credible for pet hair on suitable surfaces.

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

Low-pile carpet handling was good, with reviewers reporting successful pickup on carpet and enough mop lift for most short-pile carpet.

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

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

Crevice pickup was a strength in the Vacuum Wars test, where results were well above average.

The absence of dirty-pad sensing was treated as a limitation because the robot cannot detect dirty pads and return on demand.

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

Reviewers praised the shine and appearance after cleaning, including fresh shine on tiles and smooth, shiny surfaces.

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