Which model you go for will depend on your needs.
Both are premium priced appliances, with the WashG1 the cheaper of the two.
In the UK, it’s599.99for the WashG1 and799.99for the V15s Detect Submarine.
Finally, shoppers in Australia can get the WashG1 forAU$949.
Prices for the V15 on its own start from $749.99 / 649.99 / AU$1,449.
In fact, that’s exactly what it is the difference is entirely in the additional mopping floorhead.
The standard version is based on the V15 vacuum.
The V15s Detect Submarine will typically come with two vacuuming floorheads (plus the separate mop).
All of this means the V15s can be used for a wide variety of vacuum cleaning tasks.
The mop floorhead contains one velvety roller, and clean and dirty water tanks.
Unlike most of today’sbest wet-and-dry vacuums, there’s no suction when the machine is in mopping mode.
The floorhead also includes secondary rollers with big nylon bristles, designed to tackle solid mess.
A key point of difference is that the WashG1 will separate solid and liquid waste as it cleans.
This makes emptying easier and is good news for long-term maintenance.
Dyson also specifically addressed the Submarine’s leaking issue when designing the WashG1.
There, each tank is individually sealed with a screw top.
Overall, though, it’s far, far better than on the Submarine.
That last one is the wettest of the lot, and is designed for ingrained dirt.
Both models feature a small LCD screen on which to display a range of information.
However, you could view this for yourself because the tank on this model is mounted on the handle.
Plus, it comes with a drip tray for when the Submarine floorhead is wet.
This is useful for catching spillages when removing the mop head, too.
In fact, the mop floorhead comes apart and can be completely rinsed out.
(For vacuuming, the dust cup is the easy-empty Dyson style one.)
A point of difference is that the WashG1 comes with a self-clean cycle.
This needs to be supplemented with occasional deep cleans.
The Dyson V15s Detect Submarine’s mop floorhead has just one velvety mop roller
For this, all the rollers can be removed and rinsed, as can the solid waste tray.
The rest of the floorhead doesn’t come off, though.
The weight is distributed differently on each machine.
The WashG1 has multiple different rollers, and a tray for solid waste
The placement of the rollers is slightly better on the WashG1 versus the V15s Submarine.
However, both are generally very good at getting up close to the edges of rooms.
It’s one of the verybest cordless vacuumson the market.
The water tanks on the V15s are small, and integrated into the floorhead
Moving on to mopping.
The Submarine also isn’t really geared towards liquid and debris spillages cereal and milk, for instance.
The Submarine, however, has a vacuum floorhead(s) for that.
The tanks on the WashG1 are much larger and sit on the front of the handle
Both the WashG1 and V15s are cordless cleaners.
The motor will automatically pause when the handle is clicked upright, so battery isn’t wasted.
The V15s promises a maximum of 60 minutes of cleaning, but in vacuum mode.
The V15s has one water mode, and the LCD screen shows remaining clean water
Dyson WashG1 vs V15s Detect Submarine: which should I buy?
You’ll also appreciate the self-clean cycle.
The V15s is good for maybe a large living room before you’ll need to refill.
The WashG1 has various modes, and uses its screen to provide a range of info
The WashG1 needs to dock on the floor.
Do note that you’ll need to store the Submarine’s mop floorhead separately, though.
The WashG1 has a minimal floor dock
On the V15s, the whole mop section can be rinsed out
The floorhead design is slightly better on the WashG1 (right) in terms of the roller placement
The V15s offers excellent vacuuming
This tray on the WashG1 collects solid waste
