Key Features of the Dyson V15s Wet Dry Vacuum
Three Specialized Cleaning Heads
The Dyson V15s Detect Submarine comes with three distinct cleaning heads, each designed for specific surfaces and cleaning needs:
Submarine Wet Roller Head
The innovative wet cleaning attachment features a motorized microfiber roller that dispenses clean water from its built-in tank. As it cleans, it extracts dirty water into a separate chamber, effectively washing hard floors and removing tough, dried-on stains.
Fluffy Optic Cleaner Head
Designed specifically for hard floors, this soft roller head features Dyson’s green laser illumination technology that reveals microscopic dust particles invisible to the naked eye. The soft brush effectively captures fine dust, pet hair, and larger debris.
Digital Motorbar Cleaner Head
This versatile head works on both carpets and hard floors with powerful suction and an anti-tangle brush bar that automatically clears wrapped hair. Adjustable gates at the front optimize suction for different floor types and debris sizes.
Intelligent Cleaning Technology
The V15s Detect Submarine incorporates Dyson’s latest smart cleaning technologies:
- Piezo Sensor: Continuously counts and sizes dust particles as you vacuum, displaying the information on the LCD screen
- Automatic Suction Adjustment: Intelligently adapts power based on dust levels and floor type for optimal cleaning and battery efficiency
- LCD Screen: Displays real-time information including particle count, cleaning mode, and remaining battery life
- Green Laser Detection: Illuminates microscopic dust particles on hard floors that would otherwise be invisible
Wet Cleaning Performance
The Submarine wet roller head represents Dyson’s first venture into wet cleaning technology. Here’s how it performs:
The Submarine head did not disappoint, mopping up most of these really tough dried-on stains in one or two back-and-forth passes, which is really good.
The wet roller excels at removing dried-on stains from hard floors, with its motorized microfiber roller providing mechanical scrubbing action. The water dispensing system keeps the roller consistently damp without oversaturating your floors.
However, it’s important to note that the Submarine head doesn’t vacuum simultaneously—there’s no suction in wet cleaning mode. For best results, Dyson recommends vacuuming floors first, then switching to the wet roller head for mopping.
Important: The Submarine wet roller head is exclusive to the V15s model and cannot be purchased separately for use with other Dyson vacuums, including the standard V15 Detect.
Battery Life and Charging
| Power Mode | Estimated Runtime | Best For |
| Eco Mode | Up to 60 minutes | Light cleaning on hard floors |
| Auto Mode | 30-45 minutes | Regular cleaning with adaptive power |
| Boost Mode | 8-12 minutes | Deep cleaning of heavily soiled areas |
| Wet Cleaning | ~30 minutes | Mopping hard floors (up to 1,000 sq ft) |
The V15s features a detachable lithium-ion battery that provides up to 60 minutes of cleaning time on the lowest power setting. The intelligent power management system, combined with the auto-adjusting suction, helps optimize battery usage based on the cleaning task.
Charging takes approximately 4.5 hours from empty to full, and the battery can be easily removed for replacement or to charge separately. The LCD screen provides a real-time countdown of remaining battery life, adjusting estimates based on the current power mode and attachment being used.
Usability and Maintenance
Everyday Use Experience
The Dyson V15s Detect Submarine offers a premium user experience with thoughtful design elements that make cleaning more efficient:
- Weight and Balance: At 6.03 pounds, it’s slightly heavier than the standard V15 but remains manageable for most users
- Maneuverability: The swivel steering and balanced design make it easy to navigate around furniture and into tight spaces
- Noise Level: Operates at approximately 75 decibels, which is moderate for its power class
- Transformation: Quickly converts to a handheld vacuum for above-floor cleaning with one-click attachment changes
- Storage: Wall-mounted dock provides convenient charging and storage without a large footprint
Maintenance Requirements
Keeping the V15s in optimal condition requires regular maintenance:
Dust Bin and Filters
- 0.77-liter dust bin capacity with hygienic emptying mechanism
- Whole-machine HEPA filtration captures 99.99% of particles
- Washable filter should be cleaned monthly
- Empty dust bin after each use for optimal performance
Wet Cleaning Components
- 300ml clean water tank covers approximately 1,000 sq ft
- Dirty water chamber should be emptied after each use
- Microfiber wet roller is machine washable
- Drip tray included for storing wet roller between uses
Real-World Performance Testing
Dry Vacuuming Performance
We tested the V15s Detect Submarine across various floor types with different debris types:
| Surface Type | Fine Dust | Pet Hair | Large Debris |
| Hardwood (Fluffy Optic) | Excellent (98%) | Excellent (99%) | Excellent (95%) |
| Hardwood (Digital Motorbar) | Very Good (92%) | Excellent (97%) | Good (88%) |
| Tile | Excellent (96%) | Excellent (98%) | Very Good (93%) |
| Low-Pile Carpet | Very Good (94%) | Excellent (96%) | Very Good (90%) |
| Medium-Pile Carpet | Good (89%) | Very Good (92%) | Good (85%) |
The V15s excels in dry vacuuming performance, particularly with the specialized heads for different surfaces. The Fluffy Optic head is exceptional on hard floors, while the Digital Motorbar provides strong performance across all floor types.
Wet Cleaning Performance
The Submarine wet roller head was tested on various stains and spills:
| Stain Type | Performance | Passes Required |
| Dried Coffee | Very Good | 1-2 |
| Muddy Footprints | Excellent | 1 |
| Sticky Juice | Good | 2-3 |
| Pet Accidents (Dried) | Good | 2-3 |
| Fresh Spills | Fair | Multiple |
The wet cleaning performance is impressive for dried-on stains but less effective for fresh spills or large liquid messes. As noted in testing, it’s best to vacuum first, then switch to the wet roller for optimal results.
Best Practice: For optimal wet cleaning results, vacuum the floor thoroughly first, then switch to the Submarine wet roller head. This two-stage approach delivers the best cleaning performance.

Frequently Asked Questions
Can the Submarine wet roller head be used with other Dyson models?
No, the Submarine wet roller head is exclusive to the V15s Detect Submarine model. Due to programming differences, it cannot be used with other Dyson vacuums, including the standard V15 Detect.
Can I use cleaning solutions with the Submarine wet roller head?
Yes, the Submarine wet roller head is compatible with gentle, common floor detergents when used according to usage guidance. Dyson recommends avoiding bleach or high-foaming formulations and following the manufacturer’s dilution instructions.
How does the Dyson V15s compare to dedicated wet/dry vacuums?
The Dyson V15s differs from traditional wet/dry vacuums in that it doesn’t simultaneously vacuum and mop. Instead, it offers exceptional vacuum performance with a separate wet cleaning function. This approach delivers superior vacuum performance on carpets compared to most wet/dry vacuums, but requires switching between heads for different cleaning tasks.
How much area can the Submarine wet roller head clean on one tank?
According to Dyson, the 300ml water tank in the Submarine wet roller head can clean over 1,000 square feet of hard flooring on a single fill.
What’s the difference between the V15s Detect Submarine and the standard V15 Detect?
The main differences are: 1) The V15s includes the Submarine wet roller head for mopping capabilities, 2) Only the V15s is compatible with the Submarine wet roller head, and 3) The V15s is about 1.5 pounds heavier than the standard V15. Both models share the same 240AW suction power, battery specifications, and other core features.
Final Verdict: Is the Dyson V15s Wet Dry Vacuum Worth It?
The Dyson V15s Detect Submarine represents a significant innovation in home cleaning technology, combining Dyson’s industry-leading vacuum performance with effective wet cleaning capabilities in one versatile device.
As a cordless vacuum, it’s right up there with the best of the best. Its suction, features, and dry attachments are literally state of the art. As a mop, it’s uniquely good with the most important stuff, such as scrubbing dried-on stains and generally mopping floors, and it’s incredibly easy to use.
For homeowners with mixed flooring who value convenience and performance, the V15s offers a compelling solution that reduces the need for multiple cleaning devices. The space-saving design, exceptional vacuum performance, and effective stain removal make it a worthwhile investment for those who can accommodate its premium price point.
However, those seeking a true all-in-one solution that simultaneously vacuums and mops might prefer alternatives like the Roborock F25 Ultra or Tineco Floor One S5. The Dyson’s two-stage approach (vacuum first, then mop) delivers superior results but requires switching between heads.
The Dyson V15s Wet Dry Vacuum earns our Editor’s Choice recommendation for its exceptional performance, versatility, and innovative features. While it comes at a premium price, the current 33% discount makes it a more accessible investment in simplified home cleaning.
