Compare Dyson V15s Detect Submarine Wet Dry Vacuum vs Dyson V15 Detect Cordless Vacuum

The accessory set was widely praised as versatile and complete, with multiple cleaning heads and specialty tools for floors, crevices, hair, stairs, and upholstery.

The attachment set is repeatedly praised as broad and useful, especially the laser fluffy head, hair screw tool, dusting tools, crevice tools, and specialized above-floor accessories.

Design comments leaned positive on the colorful, quirky Dyson styling, though one reviewer felt the plastic mop head looked more toy-like than premium.

Design impressions are positive, with reviewers describing the V15 as a good-looking stick vacuum with Dyson’s polished finish.

Smart features were praised for auto suction adjustment, battery efficiency, particle detection, and display feedback, though there was no app-centered praise.

Smart automation is a clear strength: reviewers praised dirt detection, auto suction, particle sensing, floor detection, and battery optimization.

Airflow blowback was a negative edge case, with one reviewer getting a blast of vent air when cleaning under low furniture.

Area rug handling was generally positive across rugs and mixed floor homes, including thick-pile and delicate rug examples.

Area-rug handling is a weak spot, with reviewers describing lighter rugs being dragged, pushed around, or lifted by strong suction.

Setup ranged from very easy to confusing: several reviewers assembled it quickly, while others needed manuals, videos, or clearer instructions for the Submarine head.

Battery and charging feedback was strong overall, with long runtime, useful countdowns, fade-free behavior, and removable-battery benefits.

Battery and charging are mostly strong thanks to swappable batteries and dock charging, but reviewers noted short boost-mode runtime and some real-world recharge limits.

The dry bin was viewed as adequate and generally usable, but some reviewers still had to reach in for stuck hair or debris.

Bin feedback is only moderate: reviewers described the dust container as average or under one liter, implying more frequent emptying than larger cordless models.

Build quality was generally strong for the main vacuum, but some reviewers criticized plastic feel or dock/head design elements.

Build quality is generally praised as robust, beefy, well-constructed, and durable, with several reviewers contrasting it favorably against cheaper competitors.

High-pile and thicker carpet pickup was generally workable but less dominant, needing slower passes or more effort with larger lightweight debris.

High-pile evidence is negative: reviewers warned it can get stuck on shag or is not ideal for high-pile carpeting.

Low-pile carpet pickup was one of the strongest areas, with reviewers describing carpets as nearly new, excellent, or crushed in tests.

Low-pile carpet evidence is positive but limited, with one reviewer saying the V15 picked up debris seamlessly across low- and mid-pile carpets.

Medium or conventional carpet pickup was praised in one hands-on review for pulling dust, bunnies, and grime from carpeting.

Medium-pile and general carpet evidence is strong overall, with repeated perfect or near-perfect sand/deep-clean results, despite one caveat about the wrong head not reaching deep.

Debris handling through the mop head was a recurring weakness, especially with dry debris, liquid mixed with solids, cereal, small debris, or wand blockages.

Clogging evidence is mixed: one owner reported occasional user-caused clogs, while another praised the hair-screw tool for handling large clumps of fur without clogging.

Comparative performance was favorable against Dyson's V15 lineage, with the Submarine treated as comparable to or based on a top cordless platform.

Comparative performance is mostly excellent, with the V15 often beating or ranking near the top of other cordless vacuums, though upright vacuums can outperform it on some carpet messes.

The LCD and smart display were often praised, but the trigger operation and some particle-readout usefulness drew repeated complaints.

Controls and UI are useful but somewhat mixed: reviewers liked the LCD, battery readout, alerts, and particle data, while some found the particle counter unnecessary.

The handheld conversion was praised for sofa, mattress, and tight-spot cleaning.

Handheld conversion is useful for cars, stairs, tight spots, and upholstery, though one reviewer noted the handheld shape can be tiring for long sessions.

The cable-free design was praised for portability around domestic cleaning tasks.

Cordless convenience is praised by daily users and editors for making quick, tricky, and routine cleaning easier.

Crevice and groove pickup was mixed, with one review praising nooks-and-crannies cleaning but lab testing showing weak deep-crevice pickup from the mop head.

Crevice pickup evidence is excellent in one test, where the V15 quickly lifted sand from a groove and tied for the top result.

Cyclone performance received one positive assessment that the core dust-separation technology seemed to do the job.

Cyclone performance has limited but positive evidence, with one reviewer saying Dyson’s multi-cyclone separation seemed to work well.

Debris illumination was one of the most consistently loved features, repeatedly helping reviewers see hidden dust and make vacuuming more thorough.

Debris illumination is a standout feature, with many reviewers saying the green laser reveals hidden dust and pet hair better than typical LED lighting.

Dirty-water sensing was a clear weakness in TechRadar's review because the display only showed clean-water level, not dirty-water buildup.

Dried-on stain performance ranged from excellent one- or two-pass results to needing many extra passes or struggling with overnight sticky stains.

Ease of use was mostly positive for maneuvering and day-to-day cleaning, but push resistance, many parts, and trigger fatigue created caveats.

Ease of use is a major positive, with reviewers praising easy movement, satisfying cleaning, simple passes, and a pleasant overall experience.

Edge and baseboard cleaning was mostly positive, but one lab review found the exposed roller could miss debris at wall contact.

Mess control was polarized: dry-bin emptying could be easy, but the dirty-water compartment, mop debris, and cleanup were messy in several reviews.

Emptying is generally praised as clean and easy with Dyson’s mechanism, though the smaller bin means more frequent emptying.

Battery efficiency earns praise because auto modes and suction adjustment help optimize power use, though this is runtime-focused rather than measured kWh evidence.

Filtration and dust containment drew strong praise, with reviewers describing the filtration as excellent and the system as keeping fine flour or microscopic dust well contained.

Filtration and containment are a major strength, with reviewers repeatedly noting sealed canisters, fog/smoke-test success, HEPA-style capture, and cleaner exhaust.

Floor drying time was praised in two reviews, with quick drying and floors not left saturated after mopping.

Floorhead design was strong for dry heads and surface matching, but the separated vac-mop layout reduced the all-in-one feel.

Floorhead design earns praise for the balance of the motorbar and fluffy head, but reviewers also note that using two heads is less integrated than dual-brush competitors.

Fresh liquid pickup was useful for small spills and standalone liquids, but multiple reviews warned against large wet spills or wet-solid mixtures.

One reviewer noted hair could get trapped in crevices and need manual attention.

Carpet hair pickup was strong, lifting ingrained long hair and fur well in hands-on testing.

Carpet hair pickup is strong, with reviewers praising the hair screw tool, high-torque brush, and minimal wrap on longer hair.

Hard-floor hair pickup was praised across tests, especially with the Fluffy Optic head and strong suction.

Hard-floor hair pickup is very strong because the laser reveals hair and reviewers saw excellent hard-floor hair visibility and removal.

Hair-wrap resistance was mixed: Dyson's anti-tangle tools worked well in some tests, but longer hair still wrapped or needed cutting free in others.

Hair-wrap resistance is one of the clearest strengths, with repeated praise for anti-tangle heads and hair screw performance, though one reviewer found regular cleaning still necessary.

Hard-floor fine-dust pickup was excellent, especially with the Fluffy Optic head and laser revealing fine dust, sugar, hair, and corner debris.

Hard-floor fine-dust pickup is excellent, with reviewers repeatedly praising the laser fluffy head, fine debris visibility, sand pickup, and dust removal.

Large hard-floor debris performance was mixed: dry vacuum heads often performed very well, but the mop head struggled with cereal, rice, and large pieces.

Large hard-floor debris intake is generally strong, but one reviewer noted very large particles can be harder for the V15 motorhead than for a Shark dual-clean design.

Headlight performance was praised as better than typical LED headlights in one lab comparison.

The laser/headlight function has limited but very positive long-term evidence, with one owner saying it kept working reliably.

One review highlighted the product's versatility as the factor that sets it apart from other wet-dry mops.

Innovation is strongly praised, especially the laser, particle sensor, auto suction, and overall premium cordless feature set.

Kid-friendliness was noted positively when the dust-revealing head made a child's room vacuuming more fun.

Low-profile capability was excellent in lab testing because the vacuum could fully lay flat.

Maintenance was mixed: dry-vac maintenance could be straightforward, but the mop head requires washing, drying, and manual cleanup after use.

Maintenance is mixed: washable parts and easy filter/bin access help, but several reviewers said the vacuum still needs regular cleaning or demanding upkeep.

Maneuverability was mostly praised for swivel, lay-flat ability, easy gliding, and small head size, though some reviewers felt effort or fatigue on certain surfaces.

Maneuverability is a major strength, with reviewers praising steering, weight distribution, tight-corner movement, and ease compared with bulkier competitors.

Mopping performance was useful for light cleaning, small spills, and general maintenance, but reviews agreed it is not a full true wet-dry or deep-clean replacement.

Noise feedback was mixed: one lab result found mopping slightly quieter than average, while another reviewer found Boost mode very loud.

Noise feedback is mixed: one comparison found the Dyson more pleasant sounding, but several reviewers called it noisy or measured it as among the loudest cordless options.

Onboard tool storage was weak because one review found more accessories than mounting solutions.

Ownership-cost feedback was limited and mixed, mentioning optional spare batteries and likely mop-roller replacement costs.

Ownership cost evidence is mixed: washable filters reduce replacement waste, but reviewers noted parts or batteries can be difficult or expensive.

One lab review saw promising long-term durability in the Submarine attachment's lightweight, sturdy plastic construction.

Long-term durability evidence is strongly positive from a two-year owner who said the vacuum still held suction and stood the test of time.

Overall impressions were positive but qualified: reviewers loved the vacuum and versatility, while the mop, maintenance, tanks, and price created tradeoffs.

Overall sentiment is very positive: reviewers repeatedly called it best-in-class, a favorite, a top premium choice, or an outstanding all-around cordless vacuum.

Packaging was praised for secure, recyclable cardboard protection.

Pet-related feedback was positive: dog owners liked the mop option for paw prints and reviewers found pet hair pickup strong, though hair wrap still required attention in some tests.

Pet evidence is strongly positive: reviewers praised the hair screw tool, cat-hair visibility, upholstery pet pickup, and suitability for homes with shedding animals.

Value was one of the most divided areas: reviewers liked the added mop at Dyson-tier performance, but repeatedly flagged the high price or weak mop premium.

Value is polarizing: many reviewers still called it worth the money or a better premium value on sale, but price remained one of the most repeated drawbacks.

Runtime was a strength, with many reviewers reporting enough battery for homes, long mop runtime, or useful auto-mode endurance.

Runtime is mostly strong, often reported around 45–80 minutes depending on mode, but high-power settings and some real-world apartments exposed battery limits.

Sanitizing feedback was negative because the Submarine cannot steam-sterilize floors.

The lack of an auto self-cleaning cycle was a repeated weakness, making mop-head cleanup more manual than competing wet-dry vacuums.

The self-propelled mopping feel was praised as lightweight and easy to propel along.

Liquid delivery feedback was mixed: some liked the controlled water output, while others disliked the single wet mode and lack of water-flow adjustment.

Stair-cleaning feedback was favorable where the hair screw and smaller tools were used for stairs, furniture, and pet-related jobs.

Stair cleaning evidence is positive but limited, with one reviewer saying the bending wand made stairs easier.

The product does not provide steam cleaning, and one review treated that as a limitation versus hot, sterilizing mop methods.

Storage feedback was split: the compact attachment system helped in small spaces, but the vacuum is not freestanding and several reviews complained about attachment or dock storage.

The main storage-stability complaint is that the V15 does not stand upright on its own, despite otherwise strong handling.

Streaking and residue were recurring mop-head concerns, especially after pauses, large spills, dirty rollers, or uneven initial water flow.

Reviewers consistently praised the vacuuming side as powerful, with strong suction and airflow across general cleaning, carpets, hard floors, and hard-to-reach areas.

Reviewers consistently rated the V15 as extremely powerful, with repeated praise for class-leading suction, airflow, and real-world pull on carpets, rugs, and hard floors.

Heavy-duty suitability was limited; reviews repeatedly framed the mop as better for light, regular cleaning than deep grime or full mop-and-bucket replacement.

Heavy-duty suitability is positive for everyday and deeper cleaning, with reviewers citing strong whole-home cleaning, debris pickup, and high overall removal scores.

Small-space suitability was strong because reviewers saw the compact, multi-function design as a way to avoid owning multiple floor-cleaning devices.

One reviewer specifically praised Dyson customer service as excellent and efficient for support and faulty-part replacement.

Reliability evidence is mixed-positive: owners reported strong long-term reliability, but one reviewer noted comments about parts, service, and Dyson responsiveness.

Surface safety feedback was positive from a reviewer who felt the head protected tile from scratches.

Tool changes were usually quick and easy, but several reviewers disliked the extra reconfiguring needed because vacuuming and mopping require separate heads.

Tool changes are split: one long-term user found Dyson parts easy to remove, while another reviewer disliked needing to switch heads for some carpet and rug messes.

Under-furniture pickup was praised in one review for the thin wand and flexible head joint.

Under-furniture evidence is positive but mostly about visibility and access rather than a dedicated pickup test.

Above-floor and upholstery pickup was praised, especially for sofa, dog-bed, mattress, shelf, and couch-corner use.

Above-floor and upholstery pickup is a strength, especially with the hair screw tool and crevice/dusting attachments for couches, vehicles, shelves, and furniture.

Versatility was a major strength because the machine combines high-end dry vacuuming with a mop head and broad attachment set.

Versatility is mostly strong across floors, pet messes, daily cleaning, and handheld tasks, though one reviewer noted the need to switch heads reduces convenience.

Water tank feedback was mixed to negative: reviewers liked the reach of the small tank in some rooms, but repeatedly called the reservoirs small or spill-prone.

Weight feedback was mixed: some found it light and easy, while others reported hand, thumb, or forearm fatigue.

Weight feedback is mixed: many reviewers liked the V15’s lighter balance versus premium rivals, while some found the handle/trigger tiring or not the lightest option.

One reviewer successfully cleaned a delicate wool woven rug despite initial hesitation.
