How to set up your Dyson vacuum
User manual
Download the user manual for your Dyson V12s Detect Slim Submarine™ wet and dry vacuum cleaner.
Charging your battery
It's important to charge the battery before using your vacuum for the first time. This helps the battery monitoring system's algorithm more accurately calculate remaining run time.
Dock set up and charging
You will receive one of the following docking stations with your machine.
Fitting the wall dock
Before setting up the wall dock, please download your user manual and read the instructions carefully. Or watch our video guide.
Setting up the Floor dok™
Before setting up your Floor dok™, please download your user manual and read the instructions. Or watch our how-to video below.
Features
Get to know your LCD screen, displays and power modes.
Getting to know your power modes
Your vacuum has three power modes for dry vacuum-cleaning tasks: Auto/Med mode, Eco mode, Boost mode. Change mode by tapping the selection button.
Get to know your power modes for wet cleaning
When you attach the Submarine™ wet roller head, a water droplet icon appears on screen, indicating automatic switch to wet cleaning.
Understanding your LCD screen
During cleaning, your LCD screen shows the particle count graph, with remaining run time colour-coded to indicate the power mode selected.
How the graph works
As you vacuum, a piezo sensor counts and measures the microscopic particles picked up. Results are displayed in a graph on-screen, with particles ranked into four sizes, from 0–500 microns (µm) and above.¹
Yellow bar
10µm – particles as small as allergens and pollen
Orange bar
60µm – particles as small as microscopic dust and skin flakes
Pink bar
180µm – particles as small as dust mites and fine sand
Purple bar
500µm – particles as small as sugar granules
Powerful cleaning, measured in microns
The graph is available in all power modes, with all accessories. Like our famous transparent bin, it shows how much dust you've removed after every clean. To reset the graph, charge for 30 minutes, or remove the battery for 15 seconds.
How do I know I've achieved a deep clean?
When lots of dust is being vacuumed, the graph rises quickly. But as less and less dust is picked up, it slows down, letting you know you've achieved a thorough deep clean.
Getting to know your cleaner heads
Your Dyson V12s Detect Slim Submarine™ wet and dry vacuum cleaner is engineered for all-in-one cleaning power. Simply switch the cleaner head according to the cleaning task and surface.
Submarine™ wet roller head
Washes hard floors – tile, stone, wood, ceramic, vinyl, linoleum and laminate. The motorised wet roller picks up liquids, debris and tough stains. For best results, it's important to wash the Submarine™ wet roller head after every use.
-
Fluffy Optic™ cleaner head
Cleans hard floors. Dyson illumination makes invisible dust visible on hard floors, showing you where to clean. Anti-static black carbon fibre filaments pick up fine particles from hard floors and crevices.
-
Digital Motorbar™ cleaner head
Deep cleans carpets and rugs. The motorised brush bar drives stiff nylon bristles into carpet to remove deep-down dust. Polycarbonate hair removal vanes automatically de-tangle hair from the brush bar as you clean.

-
Emptying and cleaning the bin
You can help to maintain suction by emptying the bin before the debris rewaches the MAX line. Remove the bin from the machine to clean thoroughly.
-
Checking for blockages
If your machine detects a blockage, the motor will pulse six times to alert you – and you won't be able to continue until the blockage is cleared. Remove the wand, bin and cleaner head to find and clear the blockage.
Changing the battery
If you have an additional battery, you can switch batteries to achieve longer cleans. Simply press the red battery release button, and slide the battery off your machine. Your extra battery clicks into place. Watch the video.
Washing the filter
Your Dyson V12s Detect Slim Submarine™ wet and dry vacuum cleaner has a washable filter. We recommend washing it once a month to maintain optimum suction power.
-
2. Remove dust and debris
Tap your filter unit lightly on the side of the sink or bin, to remove loose dust and debris.
-
3. Wash the filter
Wash the filter with cold tap water, gently squeezing the water out with your hands. Avoid using detergent or washing in a dishwasher or washing machine.
-
4. Gently shake
Fill the inside with water, cover both sides with your hands, and shake lightly. Wash until the water is clear.
-
5. Dry for at least 24 hours
Allow the filter to air dry in a well-ventilated area for at least 24 hours, with the wide mouth facing down.
-
6. Let it dry completely
Your filter must be completely dry before you return it to your machine, or it could damage the motor. Do NOT dry in a tumble dryer, microwave or near a naked flame.
-
1. Turn off the power
Remove your vacuum from the docking station and twist the filter counterclockwise to remove it from the body.

FAQs
The wet roller can be washed with a common household anti-bacterial detergent, diluted according to the manufacturer's recommended ratio. We recommend doing this after each clean to maintain hygiene.
Only the Dyson SubmarineTM wet roller head should be used to pick up wet debris and liquid spills. Engineered with intelligent power diversion and mode detection, all aspects of wet cleaning are contained within the wet roller head. Water and debris is extracted from the roller into the waste tray, which sits directly behind the wet roller using Dyson’s new wet technologies.
The Dyson Submarine™ wet roller head is not compatible with any of our other vacuums, including pre-purchased V12. To intelligently switch between wet and dry cleaning, this version of the machine has been reprogrammed. Our previous software is not compatible with wet floor cleaning.
The Dyson Submarine™ wet roller head has been engineered for hard floors.
We recommend replacing the wet roller every six months, depending on how often you use your machine, to help maintain optimum performance.

1The amount and size of dust displayed on the LCD display will vary depending on the actual usage. This function is optimized for using Auto mode with motor driven tools. Examples of debris listed may vary in particle size and density and may appear in multiple sizes. Particles smaller than 10 µm may not be detected. In-house test results based on average household usage. Based on our own research, fine dust is defined as dust with a size of 100 µm or less. Only when an increase in dust concentration determined by our own test is detected while using auto mode, the suction power is automatically increased.
