Dyson is known for pushing the boundaries of home cleaning technology, and with the WashG1 and V15s Detect Submarine, the brand has expanded its reach into wet floor cleaning. However, these two machines serve different purposes. The WashG1 is a dedicated floor washer, while the V15s Detect Submarine is a versatile vacuum with a mopping attachment.
If you’re considering upgrading your cleaning routine with one of these devices, this guide will help you determine which Dyson is the best fit for your home.
1. Overview of both devices
Dyson WashG1 – A dedicated hard floor cleaner
The WashG1 is Dyson’s first-ever dedicated wet floor cleaner, specifically designed for hard surfaces like tile, wood, and vinyl. Unlike a standard vacuum, the WashG1 focuses on mopping and scrubbing rather than suction.
Key Features:
- Two counter-rotating microfiber rollers for deep cleaning
- 26 water jets for controlled water distribution
- Dual water tank system (one for clean water, one for dirty water)
- Solid waste separation to prevent clogging
- No traditional vacuum suction
The WashG1 is perfect for homeowners who want a dedicated solution for hard floors and don’t need carpet-cleaning capabilities.
Dyson V15s Detect Submarine – A hybrid cleaning solution
The V15s Detect Submarine builds on Dyson’s powerful V15 Detect vacuum but adds a Submarine wet roller head for mopping. This makes it a 2-in-1 vacuum and mop, ideal for homes with both carpets and hard floors.
Key Features:
- Powerful vacuum suction for dust, dirt, and pet hair
- Laser dust detection for spotting fine debris
- Wet roller head attachment for mopping hard floors
- Interchangeable heads (for carpets, hardwood, and mopping)
- Cordless operation with long battery life
The V15s Detect Submarine is a great choice for those who want a single machine for vacuuming and mopping without investing in separate devices.
2. Cleaning Performance
Hard Floor Cleaning
- The WashG1 is designed specifically for hard floors and delivers deeper cleaning with its dual-roller system, making it better at scrubbing sticky messes or dried spills.
- The V15s Submarine does a good job at mopping, but it can’t vacuum and mop at the same time—you’ll need to switch heads.
Carpet Cleaning
- The V15s Detect Submarine wins here because it has a standard vacuum function for carpets, while the WashG1 can’t clean carpets at all.
- If you need an all-in-one machine for multiple surfaces, the V15s Submarine is the better choice.
3. Ease of Use & Maintenance
Maneuverability
- The WashG1 is an upright cleaner with a larger water tank, meaning it’s heavier but more efficient for larger spaces.
- The V15s Detect Submarine is lighter and more versatile, but requires changing attachments for different cleaning tasks.
Tank Capacity & Water Management
- The WashG1 has a larger water tank (1L clean water, 800ml dirty water), meaning you don’t have to refill it as often.
- The V15s Submarine has a smaller tank, so you’ll need to refill and empty it more frequently.
Cleaning & Maintenance
- The WashG1 separates solid debris from dirty water, making it easier to clean without clogging.
- The V15s Submarine requires more frequent roller cleaning to prevent streaking on floors.
4. Battery Life & Charging
- The WashG1 is a plug-in device, meaning no charging is required. It’s ready to go at all times.
- The V15s Detect Submarine is cordless, running for about 60 minutes per charge. However, using high-power settings or the wet roller may reduce battery life.
5. Price & Value
| Model | Price (Approx.) | Best For |
|---|---|---|
| Dyson WashG1 | $699 / £599 | Dedicated hard floor cleaning |
| Dyson V15s Detect Submarine | $949 / £799 | Vacuuming + mopping (all-in-one) |
- The WashG1 is more affordable and ideal for homes with only hard floors.
- The V15s Submarine is more expensive, but offers vacuuming and mopping in one device, making it more versatile.
Final Verdict: Which One Should You Choose?
Choose the Dyson WashG1 if:
✔ You only have hard floors (tile, wood, vinyl)
✔ You want deeper, more efficient mopping
✔ You don’t need a vacuum and just want a floor washer
Choose the Dyson V15s Detect Submarine if:
✔ You have a mix of carpet and hard floors
✔ You want a 2-in-1 vacuum and mop
✔ You prefer a cordless cleaner
If your home is mostly hard flooring, the WashG1 is the better choice. However, if you want one device for all cleaning needs, the V15s Detect Submarine is worth the investment.
