Dyson V12s Detect Slim Submarine Review: Flagship Wet and Dry for Indian Homes

Understand the V12s Submarine as a brilliant vacuum with a washing accessory and every decision falls into place. The V12 platform gives you 150 air watts, a five-stage filtration path, 60 minutes of dry runtime and a body light enough to take to ceiling fans and curtain rails. The Submarine head then converts it into a hard floor washer for the daily wipe-down.

The Fluffy Optic head changes behaviour in a way spec sheets cannot convey. Its angled green laser makes invisible dust strips suddenly obvious on tiles and wood, and the piezo sensor counts particles by size on the LCD as you collect them. Owners consistently report vacuuming more often simply because the machine shows them what they were missing, which is the most honest cleanliness upgrade in this entire guide.

The Submarine head itself is precise engineering with a precise brief. A motorised microfibre roller draws clean water from its 300 ml tank, washes the floor, and a squeegee plate strips the dirty water into a separate chamber. It leaves tiles properly damp-washed and streak-free. What it does not do is suction standing liquid, so a toppled tumbler of milk or a monsoon puddle at the door wants a true wet-suction machine like the Bissell HydroSteam instead.

Tank mathematics matter in larger homes. The 300 ml clean tank washes roughly one large room and a corridor before a refill, so a full 3BHK wash is a refill-twice exercise. This is consistent with Dyson's intent: a daily freshness wipe on mostly-clean floors, not a deep scrub of neglected ones.

The rating picture needs its asterisk explained. The model launched in India in 2023 and its original listing earned 4.1 stars across 118 ratings. The listing currently in stock is a newer variant page from Dyson's authorised Amazon seller, so its on-page count looks thin even though the machine's India history is established. Pricing swings between ₹55,900 and ₹64,900 with Dyson's promotion calendar, and the two-year warranty includes accidental damage cover, a genuinely useful inclusion at this price.

The maintenance profile differs from every dock-cleaning rival here: the Submarine roller is rinsed by hand under a tap after wet sessions and left to dry. It takes a minute and removes any dependence on a dock, but it is a manual habit the Tinecos have automated. Dyson's India service network remains the strongest of any brand in this guide, with doorstep support in metros and an established spare-parts pipeline.
