Dyson V15s Detect Submarine Wet Dry Vacuum Review
Bottom Line
Choose the Dyson V15s Detect Submarine if you want top-tier cordless vacuuming plus light mopping in one compact tool. Skip it if you need a true wet-dry vac for large spills, deep grime, sealed tanks, or low maintenance.
Best for
Best for mixed-floor homes or small spaces where one compact cordless tool can handle excellent dry vacuuming plus light, regular mopping. It also fits users who value dust illumination, smart suction adjustment, and a broad tool kit.
Not for
Not for buyers who need a true wet-dry vacuum that handles large wet-solid spills, deep grime, or mostly hard-floor messes with minimal cleanup. It is also a poor fit for tight budgets or users bothered by trigger operation.
Verdict
Reviewers largely agree that the Dyson V15s Detect Submarine is an excellent cordless vacuum first and a useful but imperfect mop second. The dry-vac side earns the strongest praise for suction, carpet and hard-floor pickup, debris illumination, filtration, attachments, and runtime. The tradeoff is the Submarine wet roller: it helps with light mopping, small spills, paw prints, and many stains, but it cannot vacuum and mop at the same time, struggles with larger wet-solid messes, and can leave streaks or dirty-water spills. Its compact, multi-tool design makes sense for mixed-floor homes, yet the high price, small tanks, trigger operation, and manual mop cleanup keep it from feeling like a fully polished wet-dry replacement.

Pros highlights
-
Overall impressions were positive but qualified: reviewers loved the vacuum and versatility, while the mop, maintenance, tanks, and price created tradeoffs.
-
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.
-
Reviewers consistently praised the vacuuming side as powerful, with strong suction and airflow across general cleaning, carpets, hard floors, and hard-to-reach areas.
-
Maintenance was mixed: dry-vac maintenance could be straightforward, but the mop head requires washing, drying, and manual cleanup after use.
-
Debris illumination was one of the most consistently loved features, repeatedly helping reviewers see hidden dust and make vacuuming more thorough.
-
Runtime was a strength, with many reviewers reporting enough battery for homes, long mop runtime, or useful auto-mode endurance.
Cons highlights
-
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.
-
The LCD and smart display were often praised, but the trigger operation and some particle-readout usefulness drew repeated complaints.
-
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.
-
Debris handling through the mop head was a recurring weakness, especially with dry debris, liquid mixed with solids, cereal, small debris, or wand blockages.
-
Streaking and residue were recurring mop-head concerns, especially after pauses, large spills, dirty rollers, or uneven initial water flow.
-
Mess control was polarized: dry-bin emptying could be easy, but the dirty-water compartment, mop debris, and cleanup were messy in several reviews.

FAQ
Does the Dyson V15s Detect Submarine vacuum and mop at the same time?
No. Reviews repeatedly describe it as a Dyson stick vacuum with a separate wet roller head, so you vacuum first, switch attachments, and then mop.
How strong is it as a regular cordless vacuum?
Very strong. Reviewers consistently praised suction, carpet pickup, hard-floor pickup, filtration, and the Fluffy Optic dust-revealing head.
Is the Submarine mop head good for stains and spills?
It is useful for light mopping, paw prints, small liquid spills, and many stains. It is much less convincing with large wet spills, wet-solid messes, deep grime, or full-house heavy mopping.
Are the water tanks a problem?
Several reviewers said the clean and dirty water tanks are small. The bigger complaint was the unsealed dirty-water area, which could spill or leave dirty streaks.
How much maintenance does it need?
Dry-vac maintenance is generally straightforward, but the wet head needs to be rinsed, emptied, dried, and reassembled after use. Reviewers repeatedly missed an auto self-cleaning cycle.
Is it good for pet owners?
Mostly yes. Reviewers praised pet hair pickup, dog-bed and paw-print cleaning, and anti-tangle tools, though long hair could still wrap or require manual clearing.
