Dyson Submarine is a wet hard floor cleaner: here’s what you need to know

Dyson Submarine is now available in the UK after having previously gone on sale in the US, Canada and Australia.

I first saw the Submarine – a self-contained wet roller head – just under a year ago at Dyson’s offices in Singapore and was impressed. It brings a new spin on the concept of the wet floor cleaner. I’ve now got one in hand and I’ll be bringing you a full review very soon.

The aptly named Submarine has one big disadvantage though – it’s not backwards compatible with existing Dyson vacs, even the relatively new Gen5 Detect (though it will be from 2024 models on) so you’ll need to buy a new vac to use it.

The first vacuum cleaner to launch with the new head is the Dyson V15s Detect Submarine, a special wet and dry version of the V15 Detect.

The Submarine head clips onto the end of the Dyson’s tube, just as with any other cleaning head. However, older models don’t have the software to work with it. In other words, the motor will still run and they’ll continue to try and suck.

That’s not to say it would cause an issue with the water use, however, because even on the V15s Detect Submarine the actual head doesn’t have any integration with the rest of the unit – the water stays in the head and never goes up into the cleaner, it’s just that the main vac motor isn’t running when the Submarine is in use.

How much water can Dyson Submarine hold?

The Submarine has been designed with typical efficiency in mind. The water tank is just 300ml in size, but it’ll cover 110m² – so it uses just the right amount of water. Water is pressurized as it goes onto the microfibre roller so it is evenly distributed. A slightly larger 360ml dirty water tank makes sure no debris gets back onto the floor.

Dyson’s thinking is that present wet cleaners have various frustrations around manoeuvrability, cleaning and pick-up.

I spoke to Dyson’s head of floorcare Charlie Park about the size of the Submarine’s tanks. “The bigger the tanks are, the bigger the head, the heavier it is.

So we’re like, how long do we think someone really needs to clean for? When you’re not running the vac motor, you can run the Submarine for hours without running out of power. So it really became [about] the balance of well how big do we want the clean tank and the dirty tank.”

I also asked Park about the lack of backwards compatibility for the Submarine. Was this something that could have been avoided? “I’d be overstating if I say we couldn’t have planned, but we didn’t know [at the time] we were going to do the Submarine.

“We’re aware that it would have been better if it was backwards compatible. We’re ensuring that every new [version of] V12 and V15 that we make and everything that you’ll see in markets from next year… will be capable of taking it.

“But like everything we do at Dyson, we’re learning. We’re incorporating that into our future product development. How do we ensure that we don’t get into that situation again? So like everything we move forward and try and do it better next time.”
