Support for your Dyson V12s Detect Slim Submarine™ wet and dry vacuum cleaner
Here you can find helpful tips and advice, how-to videos, your user manual and more.
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
10µm – particles as small as allergens and pollen
60µm – particles as small as microscopic dust and skin flakes
180µm – particles as small as dust mites and fine sand
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.
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.
Watch our video guides on how to keep your machine performing at its best.
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.
1. Turn off the power
Remove your vacuum from the docking station and twist the filter counterclockwise to remove it from the body.
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.
Built-in dusting and crevice tool
Wand detaches in a click to reveal a ready-to-go crevice tool stored inside for on-the-spot cleans.
Hair screw tool
Anti-tangle conical brush bar picks up long hair and pet hair – and spirals it straight into the bin. Fast.
Engineered for precise cleaning around tricky edges and into hard-to-reach narrow spaces.
Two tools in one – wide nozzle and brush, for quick switching between cleaning and dusting tasks around your home or car.
