Dyson V15 Detect vs V15s Submarine: Differences and Similarities

The biggest difference is that you can also mop with the new Dyson V15s Dectect Submarine.

Dyson recently launched a new stick vacuum cleaner: the Dyson V15s Submarine. It's the first Dyson vacuum that lets you mop. Immediately after the introduction of this stick vacuum with mopping function, I wondered how it actually differs from the Dyson V15 Detect.

In this article I compare the Dyson V15 Detect with the new Dyson V15s Detect Submarine. Discover the biggest differences and similarities and find out which one is best for you.

Dyson V15 vs V15s Submarine: the differences

When you buy a new Dyson you often have a choice of different packages. The difference of the package is in the number of Dyson parts included. For example, I previously compared the Dyson V15 Detect vs Absolute, where I concluded that the only difference is the number of accessories included. It is therefore annoying to see that other websites actually publish different test results, even though it concerns the same vacuum cleaner.

With the V15s Detect Submarine you can mop

Whether this is also the case with the Dyson V15 Detect vs the V15s Detect Submarine is not entirely clear. But what is clear is that with the Dyson V15s Detect Submarine you get an accessory with which you can mop: the Dyson Submarine mop attachment.

When introducing the new Dyson V15s Detect Submarine, Dyson only published a lot of information about this accessory. For example, there is a special hydration system that distributes the water evenly over the floor and the attachment has a water reservoir of 300 milliliters.

Price: Dyson V15s Submarine more expensive

Various media reports that the price of the Dyson V15s Submarine will be around $949. This is quite a bit higher than the regular Dyson V15 Detect, which has a retail price of $749. I would like to emphasize that the difference in price can of course also be the number of accessories included. At the time of writing, it is not yet clear which attachments you will get in addition to the new mop accessory with the new Dyson V15s Submarine.

Dyson V15 Detect vs V15s Submarine: The similarities

The Dyson V15 remains Dyson's flagship model to this day. In the in-depth guide ‘Which Dyson to buy?‘ it becomes clear that the specifications of the V15 Detect are the best: it has the longest battery life, the highest suction power and the best technology under the hood. For example, it is equipped with a piezo sensor, which automatically adjusts the suction power when necessary.

As the name of the new Dyson V15s Submarine suggests, this is the same Dyson model. Although it is not entirely clear, I do assume that the ‘s' after V15 stands for Submarine for short.

‘Detect': green laser technology

What is a clear similarity is that Dyson has given the name ‘Detect' to both models. Dyson uses the word ‘Detect' on stick vacuum cleaners that come with a floor brush with laser technology.

Conclusion: which Dyson V15 Detect is best?

When asked which Dyson V15 Detect is best, the answer depends on your needs. That is why I have listed a number of purchase motivations for each vacuum cleaner.

Choose the Dyson V15s Detect Submarine if:

  • you can wait a little longer (release date is September 2023)
  • you also want to be able to mop the floor
  • there are few carpets in the house

Dyson V15s Submarine

With the Dyson V15s Submarine you can mop and vacuum in one movement.

Choose the Dyson V15 Detect if:

  • you have a little less budget
  • the mopping function is superfluous
  • you often have soft floors in your home

Dyson V15 Detect

The Dyson V15 Detect has no mop accessories, but is a lot cheaper and available immediately.

I'll close this comparison with the following: whichever Dyson V15 Detect you choose, it's very likely that the performance will be very much the same. The biggest difference is therefore in the included mop nozzle. However, not all specifications have been announced yet. Do you want to be sure of your purchase? Then wait a little longer until I have tested this new vacuum cleaner!

  1. I have a question around the V15s compared to the latest V15 Detect.

    Of course they are not backward compatible with the new Submarine head attachment, but will the new one come with both the laser head attachment AND the Submarine attachment AND the tangle-free carpet cleaner attachment?

    Also, will the trigger on the V15s require being held down or will it operate with an ON switch like the V12 and other models?


    • Hey Christopher,

      Great questions!
      First of all, the Dyson V15s Detect also comes with a laser brush. You can tell this because the product name includes the word ‘Detect,’ which refers to the laser detect accessory. The Submarine attachment is included as standard with the V15s (the ‘S’ refers to Submarine). Whether you get the tangle-free carpet cleaner with it depends on the package you purchase. You can check the product description (for example, here) to see which accessories are included. Finally, the main body of the vacuums is the same. That also means there’s a trigger button. However, I’ve described a solution for locking the Dyson Trigger Button.

  2. Question Dyson V15 and V15S are the batteries interchangeable with each other ? Same battery on both vacuums ?
