Alright, fellas and gals, we’ve got two Dyson wet-and-dry vacuums, and they’re about as alike as fish and chips. I’ve put both the Dyson V15s Detect Submarine and Dyson WashG1 through their paces, so gear up for a straightforward comparison. Whether you need a thorough house cleaner or just something to handle your hard floors, I’ve got the scoop. And if you’re keen for more tech talk, you know where to look: GadgetLad.co.uk—the place for honest tech reviews without the fluff.
Why Consider These Models?
WashG1
This one’s perfect for those who want to vacuum AND mop in one shot, saving you time spent messing around on hard floors. It’s all about getting the job done efficiently, no frills attached.
V15s Detect Submarine
This unit is the one to take home if you want to clean just about everything in your abode. Powerful, adaptable, and set to suck up dirt from any surface. It’s practically the Swiss army knife of vacuum cleaners.
What’s Included?
WashG1
Here’s what you get with the Dyson WashG1 when you shell out your cash:
- WashG1 vacuum body featuring 1-litre clean water and 0.8-litre dirty water tanks.
- Stylish metal wand equipped with an LCD display.
- Charging dock AND a drip tray to catch any excess.
- Charger – naturally, it’s cordless.

It’s straightforward, but it’s crafted to perform one task excellently. Just don’t expect to be vacuuming carpets with this model.
V15s Detect Submarine
The V15s Submarine, however, is packed with features:
- Main vacuum body with an LCD display and a 0.76-litre dust bin.
- Submarine Wet Roller head (yep, it’s the real deal) along with a drip tray.
- Digital Motorbar cleaner head for carpets.
- Fluffy Optic cleaner head (equipped with a green laser – yes, a LASER) for hard surfaces.
- Hair Screw tool for furniture and pet fur. Nice, eh?
- Crevice tool for those pesky corners.
- Combination tool that acts like the Swiss Army knife of vacuum attachments.
- Wand clip for keeping your accessories organized.
- Charger and docking station, of course.

With all these accessories, you’ll have no excuse for a grubby corner in your home. Be it floors, carpets, upholstery, or your grandmother’s questionable curtains – the Submarine has you sorted.
What’s the Damage?
- WashG1: £599.99 straight from Dyson. Not a bargain, but come on, Dyson doesn’t do “budget,” right?
- V15s Submarine: £799.99 – another £200, but it brings a lot more to the table.
In the USA? The Submarine will set you back $949.99, while the WashG1 is priced at $699.99. Not exactly supermarket prices, but if you’re seeking quality, it’s going to cost a bit, eh?
Specifications and Features
WashG1
- Weight: 4.9kg – feels substantial but glides effortlessly.
- Runtime: up to 35 minutes – enough time to clean half your home.
- Coverage: Up to 290sqm on one tank.
- Water modes: Three levels, plus MAX mode for all that muck your dog brought in.
- Tanks: 1-litre for clean, 0.8-litre for dirty – don’t mix them up, mate.
- Self-cleaning feature – because nobody wants to wash their cleaner.
V15s Detect Submarine
- Weight: 4.1kg – a bit lighter than the Wash G1, but still solid for a stick vac.
- Runtime: up to 60 minutes – a full hour for you cleaning enthusiasts.
- Wet mode coverage: approximately 90sqm – less than the Wash G1, but this beauty handles carpets too.
- Green laser on the hard floor head – yes, lasers. For spotting dirt.
- LCD display – shows you how much power you’ve got left and tracks particles. Pretty nifty, huh?
The Negatives – Because There’s Always Something
WashG1
- No cheap cleaning solutions – using bleach or hot water is off the table, so no sanitizing.
- Rollers wear out after 25 hours, and replacements are £45! Honestly, what a rip-off.
- Edge cleaning is decent, but it struggles with corners. Get ready to clean those by hand.
- Emptying the dirty water tank is fine, but cleaning the debris filter manually – now that’s unpleasant.
V15s Detect Submarine
- Same no-bleach, no-hot-water restriction here. So, you’re not boiling away germs with this one either.
- Fairly hefty for a stick vac. Not exactly light as a feather.
- The trench that collects dirty water can leak if you overload it.
- Guess what? They brought back the trigger! You’ll need to hold it down to vacuum – prepare for a workout.
So, What’s the Final Word?
Look, they’re both excellent in their own ways, but it comes down to the type of flooring beneath your feet. If your place has a mix of carpets and hard floors, the V15s Submarine is your best bet – it can handle it all, even your grandma’s old shag carpet. But if hard floors dominate your space, the WashG1 will slash your cleaning time dramatically.
