Compare Shark PowerDetect UV Reveal Robot Vacuum vs Roborock S8 MaxV Ultra Robot Vacuum and Mop

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

Reviewers generally liked the lift system for thresholds and obstacles, though one negative review found the mop assembly could still snag.

Design impressions were mostly positive, with reviewers calling the dock refined or sleek despite its larger footprint.

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

Smart features were useful, especially app control and on-device AI, but the Shark app drew criticism for hidden, dated, or limited controls.

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

The side air jet was praised as clever in one hands-on video, but other evidence found it could blow debris the wrong way or lag behind an extendable brush.

The Shark impressed reviewers on area rugs, with one review saying the rug felt cleaner and fluffier than with a Dyson stick vacuum.

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

Setup was mostly easy in hands-on use, although one review treated the initial setup and mapping time as a noticeable process.

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

The base does not alert when the debris container is full, so the reviewer had to keep an eye on it.

Runtime was usually enough for large cleaning sessions, but one critical review argued the underlying battery is small for a flagship robot.

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

Bagless storage and reduced bag costs were praised, while the onboard dustbin size and exterior dust attraction created some mess-control complaints.

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

Build quality was challenged by one critical review that called the mop pad toy-like and flimsy.

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

Evidence on thicker or long carpet was weak, especially for kitty litter, hair, and oatmeal caught in longer fibers.

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

One reviewer found the carpet looked refreshed after a pass, but carpet-specific evidence was otherwise more mixed by pile type.

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

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

Comparative evidence ranged from strong praise over a Dyson stick vacuum to criticism that Shark lagged stronger premium competitors in features.

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

Controls and UI were split: some reviewers found the app simple, while others found map editing difficult, limited, or dated.

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

The dock cord was criticized for limiting placement options.

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

Corner and edge debris pickup was praised with the side brush and air nozzle, but a critical review said the lack of an extendable brush limited reach.

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

UV and light-based stain visibility was repeatedly praised as useful or cool, although one reviewer called it somewhat gimmicky for everyday use.

The self-emptying dock was praised for reducing fuss, though navigation back to the dock could be inconsistent in one review.

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

Dock-related noise was mixed: auto-emptying and water washing were loud, while drying was described as a lower hum.

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

Dried stain removal was one of the strongest themes, with multiple reviewers seeing it remove dried juice, coffee, soda, syrup, and hidden messes; one critic found coffee remained.

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

Ease of use was strong for basic runs but weakened by multi-floor remapping hassles and a critical review's frustration with errors.

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

Edge and baseboard mopping was generally positive, with reviewers noting wall and cabinet edges received attention.

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

The robot's edge-following during mopping was praised for giving wall and cabinet edges similar attention to open flooring.

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

Mess control was polarized: self-emptying was convenient, but reviewers also noted dust attraction, wet mop leakage, and no-fuss positives.

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

Only one opinionated review addressed energy use, criticizing the robot as energy intensive during scrubbing.

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

Floor drying was a weakness where wet mopping left floors damp for around 30 minutes or very wet in critical testing.

Floorhead design drew criticism for a weak single roller on thicker carpet and a flimsy, thin mop-pad structure in one negative review.

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

Floor shine was praised when mopping left hard floors sparkling.

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

Carpet hair pickup was mixed: one lab result was excellent, but other reviewers still saw cat hair or weak thick-carpet pickup.

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

Hard-floor pet hair pickup was excellent in Tom's Guide testing, with no visible hair left on linoleum.

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

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.

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

Hard-floor large-debris pickup was strong in lab and home testing, especially Cheerios and dry oatmeal.

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

The LED and color-light cues helped reviewers understand what the robot was doing during stains, dirt boosts, and errors.

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

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

Innovation was a highlight in positive reviews, though one critical review framed the design as an old system made to feel new.

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 strong on linoleum in Tom's Guide testing, especially with Cheerios.

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

The low profile helped the robot clean beneath a large storage bed.

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

Maintenance was helped by hands-free features and bagless ownership, but one critic recommended manually removing the mop pad to dry it.

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

Maneuverability and navigation were mixed, from confident obstacle handling to one review describing dock navigation as a nightmare.

Mapping and pathing drew mixed evidence: maps could be accurate and routes orderly, but one-floor mapping, app limits, and follow-through issues hurt confidence.

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

The mop-lifting and detaching system was widely praised for avoiding wet carpets and reducing manual intervention.

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

Mopping performance was a major strength in most hands-on reviews, though one negative review found it left wetness and residue behind.

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

Noise was a recurring concern, especially vacuum motors, auto-emptying, and water-wash cycles.

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

Obstacle avoidance was often strong, but headphones and a threshold jam showed that it was not foolproof.

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

Odor control was helped by a fresh-smelling deodorizer, while a critical review warned that a damp pad could create odor concerns.

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

Bagless operation was a clear ownership-cost advantage because reviewers emphasized not buying recurring dust bags.

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

Overall cleaning convenience was high in positive reviews, especially the ability to schedule, self-empty, and clean without intervention.

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

A critical review raised durability doubts around the thin mop-pad assembly.

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

Overall opinion was polarized: most professional and hands-on reviews were highly positive, while one owner-review was strongly negative at the price.

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

Pet-ready evidence was strong for pet hair and hidden pet-related messes, though carpet depth still affected results.

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

Value was mixed: several reviewers thought performance justified the high price, while others called the price hefty or unacceptable.

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

Privacy controls received positive attention because stain-detection images are processed locally rather than sent to the cloud.

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

Runtime was usually validated near the three-hour claim and enough for large main-floor sessions, except for one critic's battery-size concern.

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

Sanitizing evidence was limited and cautioned that UV light itself does not sanitize quickly during a pass-over.

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

The self-cleaning dock and mop cycle were praised for reducing manual fuss and restarting without user intervention.

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

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

The liquid system drew a serious negative review because of leakage, saturation, and very wet floors.

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

Storage footprint was mixed: the dock needed significant clearance, but one reviewer still found it visually unobtrusive.

Residue control was split, from syrup removal without residue to critical evidence of dirt being spread around.

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

Stuck resistance was mostly strong in positive reviews, but one critical review found the mop pad could snag and jam.

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

Vacuum suction and airflow were praised as superb or extremely effective in positive reviews, with carpet limitations showing up elsewhere.

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

Heavy-duty suitability was limited because one reviewer still preferred a regular vacuum for deep cleans.

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

Small-space performance was helped by avoiding a narrow coffee table, though dock footprint and app handling of small rooms remained caveats.

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

Reliability concerns came mainly from a critical owner review that said errors showed up constantly.

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 was strong in the setup video, where parts clicked and locked into place easily.

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

Under-furniture pickup was positive when the robot cleaned under a large storage bed.

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 sharply negative in one owner review that would not recommend paying the asking price.

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 for seamless switching among mopping, vacuuming, and combined cleaning modes.

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

Water tanks were praised for comfortable handling, but one critical review disliked the smaller dirty-water capacity.

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.
