Compare Dyson V8 Plus Cordless Vacuum vs Dyson V15s Detect Submarine Wet Dry Vacuum

Most reviews call out a useful set of included tools (crevice, soft brush, motorized heads, mini tools and a wall dock). Comparisons note newer Dysons may include more attachments, but the V8 Plus kit still covers common use cases.

The bundle is repeatedly praised for including multiple floorheads and specialty tools, but several reviews say the docking/storage options do not neatly accommodate everything.

Reviewers repeatedly describe the Dyson look as sleek and premium, with metallic finishes and a satisfying fit and finish out of the box.

Most reviewers like the premium Dyson look and finish, but a few call out plasticky feel on the Submarine head or aesthetic mismatches with some docking accessories.

A comparison review says the V8 Plus can connect to the MyDyson app for guides, device tracking, and maintenance reminders, adding light smart functionality.

The particle sensor and Auto mode are widely praised for adjusting power and visualizing what is being picked up; a few users also relied on the Dyson app/manual for fuller guidance.

A minor but real complaint appears about airflow blowing back toward the user when cleaning under very low furniture.

Thin or lightweight rugs can get pulled up by the strong suction and may stop the brush from spinning; using lower power, avoiding Max, or adding an adapter is suggested.

On area rugs, it generally cleans well, but light debris on thicker rugs can be pushed around unless you adjust technique or settings.

Unboxing and setup are portrayed as straightforward, with dock hardware included and the main pieces snapping together quickly.

Most reviewers find initial assembly straightforward, but several say the Submarine instructions are too visual or confusing and may require looking up the full manual or app.

Some reviews mention alerts or shutoff behavior when airflow is obstructed or performance cannot be maintained, which helps protect the vacuum but can interrupt a job.

Typical low/standard runtime is described around 40 minutes, charging is via a wall dock/charger, and a battery level indicator helps planning. Charge time is mentioned around 5 hours, and Max drains far faster.

Battery performance is a strong point overall, with long Eco/low runtimes and a removable battery; charging is often cited around 4.5 hours and Boost/Turbo drains quickly.

The dust cup is frequently described as small and fills quickly, so expect more frequent emptying during whole-home cleans (even though one reviewer notes it can hold a bit more than a slimmer Dyson model).

The bagless bin size is described as adequate and the emptying mechanism is mostly hygienic, though hair and clumps can occasionally stick and require a quick manual pull.

Build is described as sturdy and well-constructed, with an overall premium feel.

The main vacuum feels sturdy and well-built in most reviews, while the Submarine head and some docking solutions get more mixed feedback (plasticky feel or leakage concerns).

High-pile carpet results are more mixed: some reviews report strong pickup while lab testing shows lower scores and higher push resistance on thick carpet.

Low-pile carpet performance is typically excellent, with strong pickup even on embedded debris and hair.

One reviewer reports the roller does not clog, and detangling design callouts suggest hair is less likely to build up and require manual de-clogging.

Clogging is not a constant problem, but some reviewers report blockages with large debris (like pine needles) or residue buildup that needs manual clearing and head cleaning.

Compared with Dyson V8 and V12 Detect Slim, the V8 Plus is seen as plenty powerful and a good Dyson entry point, but less advanced in features than higher-end models.

Compared with other cordless vacuums and most mop-vacs, it is usually rated superior at dry vacuuming; the wet function is seen as convenient but not best-in-class versus dedicated wet cleaners.

Controls are simple with two power levels/modes and a basic battery indicator. The main complaint is limited power granularity versus newer models, and Max mode is best treated as a short burst setting.

The LCD and mode controls are well-liked for showing runtime and particle info, but many reviews criticize the trigger-hold design for comfort during longer cleans.

Multiple reviewers emphasize the fast conversion to handheld for cars, furniture, stairs, and quick spot cleanups, and they call the handheld mode genuinely useful rather than a gimmick.

The vacuum converts into a handheld easily, which reviewers like for furniture, stairs, and quick spot cleaning.

Convenience is a major theme: reviewers use it for frequent quick cleanups, moving between rooms, stairs, and even the car without dealing with cords.

Cordless convenience is consistently highlighted, especially for quick daily cleanups and moving between rooms without a cord.

Dedicated crevice tools are effective for edges and tight spots, but the built-in/integrated crevice solution and the Submarine head can be less effective in deep grooves or corners.

Dyson's cyclone-based design is credited with maintaining strong suction and solid overall dust handling.

In side-by-side comparison with a model that has a green dust-illumination light, the V8 Plus is implied to lack that visibility aid.

The laser illumination is one of the most praised features, repeatedly described as revealing hidden dust and improving confidence on hard floors.

Multiple reviews note the lack of a clear dirty-water level indicator, making it harder to tell when the dirty compartment needs emptying.

Handling is generally praised for good swivel and ease around tight areas, with the caveat that storing/parking mid-clean is less convenient because it does not stand on its own.

The Submarine roller can remove dried-on stains, but results vary: some tests show quick removal while others needed multiple passes and more water on older, set-in messes.

Ease of use is a common positive, from quick tool swaps to simple emptying and the overall grab-and-go nature of a cordless stick.

Overall usability is rated good thanks to strong cleaning and smart feedback, but trigger ergonomics, weight, and post-mop cleanup are recurring drawbacks.

Edge pickup during vacuuming is often excellent, while edge performance in mop mode is more mixed and can miss right along walls.

Emptying is a standout: the lever-drop design is described as fast and convenient, and the Plus model is said to improve dirt ejection for cleaner, lower-dust emptying.

The ejector-style emptying system reduces contact with dust, though occasional clumps or hair can stay behind and need a quick manual assist.

Maintenance alerts for the filter are appreciated, including prompts to wash or service filters during ownership.

A comparison review cites whole-machine HEPA filtration capturing 99.99% of particles down to 0.3 microns, and multiple reviews suggest dust exposure is minimized by the dirt-ejection/lever emptying design.

Filtration and dust containment are consistently rated strong, with a sealed system and good particle control; HEPA-level filtration is mentioned more often for certain versions or upgrades.

Floors usually dry quickly after Submarine passes, often described as only slightly damp and drying in minutes.

Fresh spill cleanup is generally quick for small liquid-only messes, but larger spills or liquid mixed with solids can overwhelm the Submarine head.

Carpet hair pickup is generally very strong, with reviewers pulling out visible hair and lint from rugs and carpeting.

Hair pickup on hard floors is consistently strong with the dry heads, while the wet head is best treated as a mop rather than a hair-collection tool.

The Motorbar detangling design and hair-focused tools are repeatedly called out for actively removing wrapped hair and handling long hair and pet fur with less tangling.

Anti-tangle performance is usually a strength (especially with the hair screw tool), but longer hair can still wrap on the main brush bar in some situations.

Hard-floor fine dust pickup is consistently excellent, helped by the laser illumination and soft roller design for revealing and collecting powdery debris.

Dry vacuum heads handle larger debris well, but the Submarine wet head struggles with bigger pieces (like cereal) and can push debris around rather than capture it.

Reviews note it is not the most advanced Dyson; newer models add screens, more power levels or auto modes, removable batteries, and dust-illumination features.

Reviewers view the concept as innovative: a flagship stick vacuum paired with a wet roller head, though several also describe the wet system as first-generation with compromises.

Kid appeal is mentioned in passing: the laser and on-screen feedback can make cleaning feel more engaging for families.

Maintenance seems manageable: filters are referenced as washable, and app-based reminders and guides can help keep upkeep on schedule.

Maintenance is a key tradeoff: standard vacuum upkeep is manageable, but the Submarine head adds regular rinsing, drying, and occasional messy dirty-water emptying.

Handling is generally strong thanks to swivel articulation and the ability to get under furniture, but some reviewers still find it heavy in-hand over longer sessions.

Mopping is best described as maintenance-level: good for routine hard-floor refreshes and small spills, but it does not vacuum while mopping and struggles more with solids, edges, and large wet messes.

Noise is generally acceptable: mop mode is often described as quiet, while Boost/Turbo vacuuming gets noticeably loud.

Tool storage is a consistent frustration: you get many tools, but there is limited onboard or dock capacity to keep everything together.

Ongoing costs are usually moderate (filters and occasional roller replacement), but the Submarine roller can add a replacement/consumable consideration over time.

The unboxing review suggests packaging can feel excessive, though the contents appear well-protected.

Packaging is described as protective and well-organized, with at least one review praising the recyclable materials and secure packing.

Reviewers highlight pet-hair focused tools and detangling heads that lift fur from carpets and furniture without constant manual cleanup, making it a strong pick for homes with shedding pets.

Reviewers with pets praise the dry-vac tools for hair and kibble, but note the Submarine mop head is not meant to pick up solid pet food while wet cleaning.

Several reviews frame the V8 Plus as a sweet spot for Dyson performance without the price of newer flagships, though you give up newer quality-of-life features like dust illumination or extra modes.

Price is a common pain point: many call it expensive and best justified only if you will use both the top-tier vacuuming and occasional mopping.

Multiple reviewers cite about 40 minutes in low/standard mode, which suits daily maintenance cleaning or smaller homes. High/Max mode is consistently described as much shorter than default, ranging from roughly 15 minutes in one review to about 4 minutes in another comparison, so it is best reserved for quick spot jobs.

Default/Eco runtimes are often around an hour or more depending on mode, with Auto mode shortening runtime when it ramps up power. Boost/Turbo runtime is consistently short, commonly under 10 minutes in testing.

Reviews repeatedly call out that there is no automated self-cleaning cycle or wash/dry base for the mop head, so post-mop cleanup is manual.

Several reviews mention the Submarine head feels self-propelled, making wet passes easier and faster.

The liquid system is simple and water-based; some reviews mention you can use a mild detergent, but there is typically only one wet mode and limited control over water flow.

A dedicated review specifically calls it great on stairs, helped by the lightweight build and handheld conversion.

With the handheld conversion and tools, stairs are generally easy to clean, especially on hard stair treads and edges.

The wall dock is praised for keeping the vacuum charged and ready, but at least one reviewer notes it does not stand upright on its own and needs the dock or a wall/corner for parking.

It stores like a typical Dyson stick via a wall dock, but it is not truly freestanding and alternative docks can be bulky; the extra heads/tools also add storage complexity.

Streaking is mixed: some report a streak-free shine, while others saw streaks or dirty-water drips, especially if the roller is paused mid-flow or the dirty channel gets too full.

Across reviews, suction is described as very strong even in the lower mode, with Max delivering a noticeable jump for spot cleans. A downside is that the power can be aggressive enough to lift thin rugs or stall the brush.

Across reviews, dry vacuuming is the standout: very strong suction and pickup on both hard floors and most carpets, though the high suction can make the head harder to push on thicker carpet.

For heavy-duty mopping or frequent large wet messes, reviews suggest it is not ideal; it is better as a light, regular maintenance mop paired with strong vacuuming.

It is often framed as a good fit for apartments or smaller homes that only want one cleaning device, since it can replace a separate vacuum plus a basic mop.

Support is mentioned less often, but Dyson customer service is described as a plus where it comes up.

The soft rollers and floorheads are generally seen as gentle on hard floors, and at least one reviewer specifically noted reduced worry about scratching tiles.

Attachments and the wand are shown as click-in, click-out simple; reviewers also like that the bin can be emptied without removing tools in use.

Dry heads and tools click on quickly, but swapping between vacuum and mop heads is required for wet cleaning and some users find the Submarine setup a bit fiddly.

Under-furniture reach is a recurring positive due to head articulation and the ability to lay flatter, though one review notes the vent can blow air toward your face in tight spaces.

Reviewers report it removes pet fur from furniture well when using the pet/hair tools in handheld configuration.

Motorized tools for upholstery and above-floor tasks perform well, especially for pet hair and furniture cleaning.

Across reviews, it is positioned as versatile for mixed flooring and above-floor cleaning thanks to multiple tools, two power modes, and strong handheld performance.

Versatility is a core theme: multiple heads let it cover hard floors, carpets, above-floor cleaning, and basic mopping, but wet cleaning requires a separate pass and head swap.

The clean-water tank is small (often cited around 300 mL), so it suits maintenance mopping more than big jobs; the dirty-water compartment can be messy and may leak if overfilled or tilted.

Reviewers repeatedly call it lightweight and easy to carry for stairs, multi-level homes, and above-floor cleaning.

Weight is frequently noted: it is manageable for many as a stick vacuum, but the handheld configuration and long sessions can feel heavy or fatiguing for some users.

At least one review reports acceptable cleaning on a delicate wool rug, suggesting it can be used carefully on wool surfaces.
