Review: We put Dyson V15s Detect Submarine wet and dry vacuum to the test

High-powered cordless stick cleaner is the firm's first vacuum with a mopping attachment

Dyson V15s Detect Submarine is a cordless stick vacuum based on the high-powered V15 model but now including the firm’s first mopping attachment.

And this iteration is quieter and lighter than its predecessor.

It's important to note that the new Submarine mopping attachment only works with this V15s Detect model and not with the original V15, the more recently released Gen5 Detect or any older stick vacuums.

Accessories bundled along with the Submarine wet roller head are a Digital Motorbar cleaner head, Fluffy Optic cleaner head, combination tool, quick release crevice tool, hair screw tool, charger, a docking station (that stores some of your tools) and the useful drip tray.

The accessories will cover you for every type of cleaning scenario.

And it comes with a replaceable battery, so you can swap out batteries after the 60 minutes of run time (depending on cleaning mode and cleaning head) and keep going for another hour if needed. The batteries take several hours to fully recharge.

Dyson V15s Detect Submarine has a top-quality build, like all Dyson vacuums. Its compact size means it is extremely manoeuvrable, giving excellent handling to users of all sizes.

And it’s got the same digital display as the V15 – so you can see cleaning modes and your battery level easily. It also displays an analysis of the information collected by the particulate sensor.

I’ve been testing Dyson Submarine out for several weeks and I am super impressed. It mops hard floors as thoroughly as you’d expect a Dyson motorised mop to.

It’s not a traditional wet and dry vacuum in the sense that it does one or the other – you either vacuum or mop, not both at the same time.

But can handle dried in food spills, muddy shoes and regular mopping with equal ease. And it glides across the floor with little effort needed.

It has two water tanks: one to hold clean water and the other for dirty water, both of which are contained in the roller head. Clean water usually lasts for about 15 minutes.

The mop roller is made of dense microfibre, which is washable and can be removed easily for cleaning. It is designed to use just water for cleaning, but you can add a no-suds detergent if you follow Dyson’s dilution ratio.

The Submarine works by saturating the soft roller head with clean water through an eight-point hydration system that ensures even water distribution and prevents oversaturation. Dirty water is extracted from the roller and deposited into the wastewater tank, keeping dirt and debris from being redistributed onto the floor.

One design flaw is the dirty water tank is not sealed but if you are mindful of this it should not be an issue.

The main caveat is that unlike Gen5 Detect, this vacuum uses a trigger rather than a direct on/off power button. A minor frustration is there are more accessories than you get storage for.

All in all, this is a one-stop shop for home cleaning and for a first attempt, Submarine does swimmingly well.
