Dyson V15s Detect Submarine Wet Dry Vacuum
2.0
Airflow blowback was a negative edge case, with one reviewer getting a blast of vent air when cleaning under low furniture.
Edge and Baseboard Cleaning (Hard Floors)
Dyson V15 Detect Cordless VacuumNo score yet
Dyson V15s Detect Submarine Wet Dry Vacuum
4.1
Edge and baseboard cleaning was mostly positive, but one lab review found the exposed roller could miss debris at wall contact.
Mopping performance
Dyson V15 Detect Cordless VacuumNo score yet
Dyson V15s Detect Submarine Wet Dry Vacuum
3.7
Mopping performance was useful for light cleaning, small spills, and general maintenance, but reviews agreed it is not a full true wet-dry or deep-clean replacement.
Sanitizing performance
Dyson V15 Detect Cordless VacuumNo score yet
Dyson V15s Detect Submarine Wet Dry Vacuum
1.5
Sanitizing feedback was negative because the Submarine cannot steam-sterilize floors.
Self-cleaning cycle
Dyson V15 Detect Cordless VacuumNo score yet
Dyson V15s Detect Submarine Wet Dry Vacuum
1.8
The lack of an auto self-cleaning cycle was a repeated weakness, making mop-head cleanup more manual than competing wet-dry vacuums.
Steam Cleaning
Dyson V15 Detect Cordless VacuumNo score yet
Dyson V15s Detect Submarine Wet Dry Vacuum
1.5
The product does not provide steam cleaning, and one review treated that as a limitation versus hot, sterilizing mop methods.
Ownership and support
Assembly and Setup

Setup ranged from very easy to confusing: several reviewers assembled it quickly, while others needed manuals, videos, or clearer instructions for the Submarine head.
Other features
Dirty water sensor
Dyson V15 Detect Cordless VacuumNo score yet
Dyson V15s Detect Submarine Wet Dry Vacuum
1.0
Dirty-water sensing was a clear weakness in TechRadar's review because the display only showed clean-water level, not dirty-water buildup.
Dried-On Stain Removal
Dyson V15 Detect Cordless VacuumNo score yet
Dyson V15s Detect Submarine Wet Dry Vacuum
3.9
Dried-on stain performance ranged from excellent one- or two-pass results to needing many extra passes or struggling with overnight sticky stains.
Energy efficiency (kWh)
Dyson V15 Detect Cordless Vacuum
4.4
Battery efficiency earns praise because auto modes and suction adjustment help optimize power use, though this is runtime-focused rather than measured kWh evidence.

Floor Drying Time
Dyson V15 Detect Cordless VacuumNo score yet
Dyson V15s Detect Submarine Wet Dry Vacuum
4.8
Floor drying time was praised in two reviews, with quick drying and floors not left saturated after mopping.
Fresh Liquid Pickup Speed
Dyson V15 Detect Cordless VacuumNo score yet
Dyson V15s Detect Submarine Wet Dry Vacuum
3.6
Fresh liquid pickup was useful for small spills and standalone liquids, but multiple reviews warned against large wet spills or wet-solid mixtures.
Hair-removal channel issues
Dyson V15 Detect Cordless VacuumNo score yet
Dyson V15s Detect Submarine Wet Dry Vacuum
3.0
One reviewer noted hair could get trapped in crevices and need manual attention.
Kid-friendliness
Dyson V15 Detect Cordless VacuumNo score yet
Dyson V15s Detect Submarine Wet Dry Vacuum
4.0
Kid-friendliness was noted positively when the dust-revealing head made a child's room vacuuming more fun.
Onboard tool storage
Dyson V15 Detect Cordless VacuumNo score yet
Dyson V15s Detect Submarine Wet Dry Vacuum
2.0
Onboard tool storage was weak because one review found more accessories than mounting solutions.
Packaging quality
Dyson V15 Detect Cordless VacuumNo score yet
Dyson V15s Detect Submarine Wet Dry Vacuum
4.5
Packaging was praised for secure, recyclable cardboard protection.
Self-propel feature
Dyson V15 Detect Cordless VacuumNo score yet
Dyson V15s Detect Submarine Wet Dry Vacuum
4.5
The self-propelled mopping feel was praised as lightweight and easy to propel along.
Solution / Liquid system
Dyson V15 Detect Cordless VacuumNo score yet
Dyson V15s Detect Submarine Wet Dry Vacuum
3.1
Liquid delivery feedback was mixed: some liked the controlled water output, while others disliked the single wet mode and lack of water-flow adjustment.
Streaking / Residue
Dyson V15 Detect Cordless VacuumNo score yet
Dyson V15s Detect Submarine Wet Dry Vacuum
2.6
Streaking and residue were recurring mop-head concerns, especially after pauses, large spills, dirty rollers, or uneven initial water flow.
Suitability for small spaces
Dyson V15 Detect Cordless VacuumNo score yet
Dyson V15s Detect Submarine Wet Dry Vacuum
4.7
Small-space suitability was strong because reviewers saw the compact, multi-function design as a way to avoid owning multiple floor-cleaning devices.
Surface safety with attachments
Dyson V15 Detect Cordless VacuumNo score yet
Dyson V15s Detect Submarine Wet Dry Vacuum
4.5
Surface safety feedback was positive from a reviewer who felt the head protected tile from scratches.
Water tank
Dyson V15 Detect Cordless VacuumNo score yet
Dyson V15s Detect Submarine Wet Dry Vacuum
2.7
Water tank feedback was mixed to negative: reviewers liked the reach of the small tank in some rooms, but repeatedly called the reservoirs small or spill-prone.
Wool carpet compatibility

One reviewer successfully cleaned a delicate wool woven rug despite initial hesitation.
Comfort and build
Low-profile design
Dyson V15 Detect Cordless VacuumNo score yet
Dyson V15s Detect Submarine Wet Dry Vacuum
5.0
Low-profile capability was excellent in lab testing because the vacuum could fully lay flat.
