Our take on the Dyson V12s Detect Slim Submarine Cordless Vacuum

The Dyson V12s Detect Slim Submarine is a cordless stick vacuum that also mops hard floors. Its standout part is the Submarine wet roller head, which scrubs and sucks up spills in one pass. It also has a green laser that shows dust on hard floors and a sensor that raises suction automatically on dirtier patches. It suits homes with a lot of hard flooring that want one machine for dry and wet cleaning. Against rivals, it is lighter and more versatile than most wet-dry vacuums, but its small dust bin and run time limit big jobs.

Questions and answers

Can it vacuum and mop at the same time?
No. You swap the Submarine wet roller head for the standard cleaner head. Dry vacuuming and wet cleaning are separate passes with different heads.
How long does the battery last?
Dyson rates it at up to 40 minutes in Eco mode with a non-motorized tool. Expect much less in Auto, Boost or wet mode.
Does the laser work on carpet?
The laser is built for hard floors, where it shows fine dust. On carpet it is not useful.
Is it good for pet hair?
Yes. The standard head and the motorbar handle pet hair on carpet and hard floors, and it converts to a handheld for furniture.
What comes in the box?
Typically the vacuum, battery and charger, the Submarine wet roller head, a cleaner head, a crevice tool and a combination or hair tool. Check the exact kit for the model you buy.
Can I use it on all hard floors?
The wet roller is meant for sealed hard floors such as tile and laminate. Avoid unsealed wood and areas where water can seep.
