Our take on the Dyson V9 Submarine Extra Dry Cordless Wet and Dry Stick Vacuum

The Dyson V9 Submarine is a cordless stick vacuum that washes hard floors and vacuums dry debris with one machine. It has a 10.14 oz clean-water tank, 40 minutes of run time and a 4.6 lb body, and it weighs far less than a mop-and-bucket setup. The best new price is $249.99 at Walmart as of November 4, 2026, and four stores carry it new, so it sits at the low end of what it has sold for recently.

Questions and answers

Is the Dyson V9 Submarine worth it?
It is worth it if most of your floors are hard and you want to wash and vacuum without dragging out a mop. If you have wall-to-wall carpet, a standard dry stick vacuum covers more of your home.
How does it compare with the regular Dyson V9?
The Submarine adds a wet roller and a 10.14 oz water tank for washing hard floors. The dry V9 is lighter and cheaper, but it cannot mop.
How long does the battery last?
Dyson rates it at 40 minutes, which is on the lowest suction setting. Expect much less at full 380 W power, so plan on charging between whole-home cleans.
Can it clean carpets?
It vacuums dry debris from carpet, but the wet washing function is for sealed hard floors only. Do not run the wet roller on carpet or rugs.
What comes in the box?
The vacuum ships with its battery, charger, wet roller head and clean-water tank. Check the listing for extra tools, since bundles vary by store.
When is it cheapest?
The current $249.99 at Walmart as of November 4, 2026 is already near the low end of its recent range. Big sales events like Black Friday and Prime Day are the usual times to watch for deeper cuts.
Where is the Dyson V9 Submarine Extra Dry Cordless Wet and Dry Stick Vacuum cheapest?
At Walmart, for $249.99, 28% under what the other stores charge, as of our latest check.
