Suction Power

The Dyson V15s Detect Submarine and Dyson V15 Detect Plus are level here, at 9.5/10 each. actual cleaning force at the head, judged on air watts where a maker publishes them and discounted where only Pa or motor watts are quoted is not what separates these two — look to the categories where the scores diverge.

Sustained Runtime

The Dyson V15 Detect Plus leads clearly here, 4.0 against 3.5 — a 0.5-point margin on how long the machine really runs on max power with the motorised floor head attached — not the eco-mode, bare-tool figure on the box. If that is what you are buying for, the Dyson V15s Detect Submarine does not close the gap elsewhere.

Filtration & Sealing

The Dyson V15s Detect Submarine and Dyson V15 Detect Plus are level here, at 9.5/10 each. whether the whole machine is sealed or a HEPA element simply sits inside a leaky body, and what the claimed rating is actually measured at is not what separates these two — look to the categories where the scores diverge.

Handling & Ergonomics

The Dyson V15 Detect Plus leads clearly here, 6.0 against 5.5 — a 0.5-point margin on weight, balance, whether power is a push-button or a trigger you must hold, and how it stores. If that is what you are buying for, the Dyson V15s Detect Submarine does not close the gap elsewhere.

Maintenance & Emptying

The Dyson V15 Detect Plus leads clearly here, 8.5 against 5.0 — a 3.5-point margin on bin or tank emptying, whether your hand ends up near the dust, self-clean quality and the ongoing cost of filters, bags and detergent. If that is what you are buying for, the Dyson V15s Detect Submarine does not close the gap elsewhere.

Battery System

The Dyson V15s Detect Submarine and Dyson V15 Detect Plus are level here, at 8.5/10 each. removable or sealed, how many packs are included, what a spare costs and whether the pack is shared across a range is not what separates these two — look to the categories where the scores diverge.

Versatility

The Dyson V15s Detect Submarine leads clearly here, 9.0 against 8.0 — a 1.0-point margin on handheld conversion, above-floor tools, carpet capability and wet-mopping ability. If that is what you are buying for, the Dyson V15 Detect Plus does not close the gap elsewhere.

Value

Pros & Cons

Dyson V15s Detect Submarine

Pros

  • +One machine covers deep dry vacuuming and wet mopping, so you are not storing two appliances
  • +The wet roller is genuinely effective on dried-on stains, and the two-tank design keeps dirty water off the floor
  • +Identical 240 air watts and sealed filtration to the standard V15 Detect — the dry half is not compromised
  • +Cheapest spare battery of any flagship here at $99.99

Cons

  • The Submarine head is a poor vacuum: it does not pick up dry debris or large spills well, so you must vacuum first and then mop
  • No self-clean cycle at all — the roller and both tanks get washed by hand every time, which is exactly what a Tineco or Roborock does for you
  • Trigger-hold operation, and 1.5 lb heavier than the standard V15 Detect
  • $1,049.99 list, and the Submarine head fits no other Dyson and cannot be bought as an add-on

Dyson V15 Detect Plus

Pros

  • +240 air watts is a genuine cleaner-head figure, not a sealed-suction Pa number — only Samsung and Levoit publish anything comparable here
  • +The laser head makes fine dust on hard floors visible, which changes how you clean rather than just how you feel about it
  • +Whole-machine sealed filtration, so what the filter catches does not leak back out through the body
  • +A genuine Dyson spare battery is $99.99 — less than half what Miele charges

Cons

  • You hold the trigger down for the entire clean; there is no latch. This is the single most common long-term Dyson complaint
  • Boost mode with the powered head lasts about 9 minutes — the '60 minutes' is Eco with a non-powered tool
  • The dock is a wall bracket that needs drilling; there is no stand in the box and no auto-empty option at any price
  • $600 street and $850 list for a 0.77 L bin you still empty by hand
