Dyson V15s Detect Submarine Wet Dry Vacuum

Verdict

The Dyson V15s Detect Submarine is an outstanding cordless vacuum with top-tier suction, tools, and smart features, plus a uniquely strong mopping head for dried-on stains and everyday hard floor maintenance. Its weaknesses with large wet spills, debris pickup while mopping, and the proprietary submarine head mean it is best for people willing to vacuum first and use the mop as a second step. If you will use both functions regularly and can live with the price and compatibility limits, it is a superb all-in-one cleaning system.

Cons

    When overloaded with a big spill or paused mid-pass, the mop head can leave streaks and residue that are harder to re-collect, sometimes requiring extra passes.
  • Accessory compatibility 1 review 2.0
    Submarine mop head is exclusive to the V15s and cannot be used with earlier Dyson cordless models or bought separately, limiting cross-compatibility and upgrade flexibility.
  • Fresh Liquid Pickup Speed 1 review 2.0
    Processes small liquid spills acceptably, but can bog down on larger volumes and slow pickup.
  • Onboard tool storage 1 review 2.0
    Dock and wand lack mounting points for all the included tools, so some attachments need to be stored separately.
  • Water tank 1 review 2.0
    Fresh-water tank and separate dirty-water reservoir work well for modest areas, but capacity is relatively small and may require refills for larger rooms or heavy-duty mopping.
