Side-by-Side Comparison
| Spec | Dyson V15 Detect Plus | Dyson V15s Detect Submarine |
|---|---|---|
| Price | $599.99 | $879.00 |
| Release Year | 2021 | 2023 |
| Machine Type | Dry cordless stick vacuum, converts to handheld | Dry cordless stick vacuum with a swappable wet roller head — not a dedicated floor washer |
| Suction (as published) | 240 air watts. Dyson publishes air watts, the only one of the three common numbers that describes work done at the cleaning head | 240 air watts. Dyson publishes air watts rather than Pa or motor watts |
| Runtime, Eco / Headline (min) | 60 | 60 |
| Runtime, Max Power (min) | 9 | Not published by the manufacturer — Dyson quotes only 'up to 60 minutes' |
| What the Runtime Claim Actually Means | Dyson's 'up to 60 minutes' is Eco with a non-powered tool. TechGearLab measured 64 min on low and 9 min on Boost with the Digital Motorbar head fitted. Dyson publishes no per-mode table. | The 60-minute figure is Eco with a non-powered tool. Dyson publishes no Boost figure and no wet-mode figure, and the Submarine head has its own motor that drains the pack faster than the dry heads |
| Removable Battery | Yes — tool-free click-in battery; one included | Yes — tool-free click-in battery. A second battery is sold separately and is not in the box |
| Spare Battery | $99.99 for the genuine Dyson click-in pack (shared with V11, Outsize and V15s Submarine) | $99.99 for the genuine Dyson click-in pack |
| Dock / Wall Mount | Wall-mounted docking station included; it must be screwed into a wall. No free-standing dock and no auto-empty base exists for this model | Wall-mounted docking station included (drilling required), plus a drip tray for the wet head. No auto-empty, no self-clean dock |
| Filtration | Whole-machine sealed filtration with a washable lifetime filter. Dyson's 99.99%-at-0.3-micron claim is stated for Boost mode | Whole-machine sealed filtration; 99.99% at 0.3 micron claimed in Boost mode |
| Bin / Tank Capacity | 0.77 L bin. Point-and-shoot ejection drives the shroud down through the bin, so your hand never goes near the dust | 0.77 L dust bin; the Submarine head carries 0.3 L clean water and 0.36 L dirty water |
| Weight (lbs) | 6.83✓ | 8.3 |
| Filters, Consumables & Self-Clean | Filter is washable and has no replacement schedule — rinse monthly. Cleaner heads and brush bars are stocked as Dyson spares | There is no self-clean cycle. The Submarine roller and both water tanks are rinsed by hand after every wet use. Replacement wet rollers are sold as Dyson spares |
| Warranty | 24 months | 24 months |
| Colors | Yellow/Nickel | Yellow/Nickel |
Category Scores
Suction Power
The Dyson V15 Detect Plus and Dyson V15s Detect Submarine 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 V15 Detect Plus and Dyson V15s Detect Submarine 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 V15 Detect Plus and Dyson V15s Detect Submarine 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
The Dyson V15 Detect Plus leads clearly here, 6.5 against 5.5 — a 1.0-point margin on what you actually get for the street price once consumables and missing accessories are counted. If that is what you are buying for, the Dyson V15s Detect Submarine does not close the gap elsewhere.

Pros & Cons
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
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
