The Dyson V9 Submarine combines vacuuming and wet floor cleaning in a single cordless system, offering a convenient solution for everyday household cleaning. It sits in Dyson’s evolving lineup of hybrid cleaners designed for users who want both dust removal and light mopping without switching tools.
This review explores its suction performance, mopping capabilities, usability, and whether it can reduce the need for traditional mopping. It’s particularly relevant for users comparing modern hybrid cleaning systems in today’s premium vacuum market. See it on Amazon.
Performance Overview
At the core of this model is strong suction consistency paired with a rotating wet roller system. On sealed hard floors, dust and fine particles are picked up quickly, often in a single pass. The cleaning path feels controlled and efficient, especially in open spaces like living rooms and hallways.
Heavier debris such as crumbs or small particles may occasionally require a second pass, depending on floor texture and movement speed. However, overall pickup performance remains stable for everyday cleaning tasks.
The wet roller system is where this device stands out. Instead of traditional dragging mops, it uses a continuously refreshed roller that spreads clean water while lifting dirt at the same time. When used properly, floors dry streak-free and feel noticeably clean, particularly in kitchens and dining areas.
Edge cleaning is less refined. Corners and tight wall lines may still require manual touch-ups, which is common in most hybrid cleaning systems.
Wet Cleaning Experience
The wet cleaning function focuses on maintenance-level cleaning rather than deep scrubbing. It performs well for light spills, dust film, and daily surface refreshment.
One of its strengths is consistency. The roller maintains even moisture distribution, avoiding overly wet patches that can damage sensitive flooring. This makes it suitable for sealed hardwood, tiles, and laminate surfaces.
However, dried stains or sticky spots may require multiple passes or manual intervention. This is expected, as the system prioritizes routine upkeep over intensive stain removal.
Overall, it reduces the frequency of manual mopping rather than completely eliminating it.
Handling and Everyday Use
In daily use, the vacuum feels balanced but slightly heavier when the wet roller is attached. Movement is smooth on open floors, though tighter spaces require more controlled handling.
Transitioning between dry debris and wet cleaning is straightforward, but cleaning speed plays an important role. Slower, steady movement produces better results, especially when using the wet function.
Pet hair behaves differently when moisture is involved. It can sometimes cling to the roller, requiring periodic cleaning during longer sessions. This is normal for hybrid systems that combine wet and dry functions.
The learning curve is minimal, but users do need to adjust their cleaning style slightly to get the best performance.
Battery Life and Efficiency
Battery performance is adequate for small to medium homes. In standard vacuum mode, it handles routine cleaning comfortably before requiring a recharge.
When using wet cleaning mode or combined operations, battery drain increases more quickly, which is expected due to additional motor load and water system usage.
If the battery runs low mid-clean, the device returns to its dock for charging. Depending on the setup, it may resume cleaning afterward, ensuring uninterrupted coverage in larger spaces.
Efficiency is balanced more toward consistent performance than extended runtime.
Hybrid Cleaning Positioning
This model is best understood as a hybrid cleaning tool rather than a full replacement for traditional vacuuming and mopping systems.
It performs well in daily maintenance routines, where floors need to stay consistently clean rather than deeply scrubbed. Its strength lies in reducing effort and simplifying cleaning workflows.
Compared to standard cordless vacuums, it adds the benefit of wet cleaning. Compared to dedicated mopping systems, it offers better dust and debris control.
The trade-off is that it does not fully excel in either category individually but performs well in both combined.
Real-World Limitations
While the system is efficient, there are a few practical limitations to consider:
- It is not designed for deep carpet cleaning
- Heavy stains still require manual attention
- The wet roller needs regular cleaning maintenance
- Edge and corner cleaning is less precise
- Battery drains faster in combined cleaning mode
These limitations are typical for hybrid cleaning devices and do not significantly affect everyday usability.
Pros and Cons
Pros
- Strong suction for daily dust and debris
- Effective wet roller cleaning system
- Consistent performance on hard floors
- Simplifies vacuuming and mopping into one tool
- Good for routine home maintenance
- Easy-to-use cordless design
Cons
- Not ideal for deep carpet cleaning
- Wet roller requires regular maintenance
- Limited edge cleaning performance
- Battery reduces faster in wet mode
- Slightly heavier with wet attachment
Comparison Insight
Compared to traditional high-powered cordless vacuums, this model focuses more on convenience than raw suction strength. It trades some deep-cleaning power for the ability to handle wet and dry cleaning in one workflow.
Against dedicated mopping systems, it offers better dust removal and faster cleanup but does not match intensive scrubbing capability.
This positions it in a middle category: a hybrid solution designed for users who want everyday convenience over specialized performance.
Final Verdict
Overall, this device delivers a balanced and practical cleaning experience for modern households. It is not designed to replace heavy-duty cleaning equipment but instead to simplify daily floor maintenance.
Its strongest advantage is convenience. The ability to vacuum and mop in one pass reduces cleaning time and effort significantly. While it has limitations in deep cleaning scenarios, it performs reliably in everyday use.
For users looking for a smart hybrid system that keeps floors consistently clean with minimal effort, this is a solid and practical option.
