Support for your Dyson V12 Detect™ Slim vacuum
Here you can find helpful tips and advice, how-to videos, your user manual and more.
Charge before first use
It's important to fully charge the battery as soon as you open the box, and after every clean. The battery and monitoring system's algorithm 'learns' over time, and fully charging your batteries helps it to more accurately calculate and display remaining run time.
Second-by-second run time
Remaining run time is shown on screen in a second-by-second countdown, which constantly updates in real time, according to the power mode you select.
To help maintain performance, your vacuum will remind you when it's time to recharge the battery, or clean the filter. It'll even help you clear any blockages.
Settings, alerts and notifications
To enter the settings menu, hold the selection button. Tap the button to scroll through the options, hold to select. Press the power button at any time to start vacuuming.
Choose your preferred language.
Turn screen and audible maintenance alerts on/off.
Switch the particle count graph on/off. When the graph is turned off, the LCD screen shows power mode and remaining run time during cleaning.
In Auto mode, suction power is automatic. More dust, more power. Set motor sensitivity to 'High', and auto suction reacts more often, to lower amounts of dust. Set to 'Low', and it reacts less often, with higher concentrations of dust.
Please charge your battery. Your machine will stop when the charge has been depleted. When run time is low, your machine will pulse three times to alert you.
Filter not sealed
The filter section is not fully interlocked. The on-screen animation shows you which sections to look at.
A blockage has been detected. Watch the animation to see which airways to check. Your machine will also pulse seven times to alert you.
Your filter needs cleaning. Follow the advice further down the page to wash your filter.
If you use Boost mode frequently, this message will appear, to help you conserve battery life.

Your vacuum has three power modes, each designed for different tasks. Change power mode quickly by tapping the selection button.

Charging your battery
You can charge your battery on or off the machine or wall dock. It can take up to 4.5 hours to fully charge your battery. When the green tick is displayed, charging is complete.
Leave it charging
Your battery is designed to be left plugged in, so it's always ready to use.
Looking after multiple batteries
If you have an additional battery, we recommend fully charging it soon after purchase, and alternating batteries regularly to prolong battery health.
Storing your batteries
If you're not using your batteries, we recommend storing them with a charge of 30%.
How to clean your filter
1. Remove your Dyson filter
Remove your filter by unscrewing the post-motor filter from the machine.
2. Remove excess dust
Tap your filter lightly on the side of the sink or in the bin, to remove any loose dust and debris.
3. Rinse filter
Wash your filter with warm tap water – gently rubbing it with your hands. Don't use detergents.
4. Give it a firm shake
Fill your filter with warm tap water. Cover the open ends with your hands and shake firmly to remove the dirt. It's important not to agitate the filter media, i.e. the pleated elements. Repeat until the water runs clear, and then firmly shake the filter to remove all excess water.
5. Leave to dry for 24+ hours
After washing your filter, leave to dry for at least 24 hours in an area with plenty of airflow, such as beside a fan or open window. When drying, position the filter with the larger end on the surface. Your filter must be completely dry before you put it back into the machine, or it could damage the motor. Don't dry in a tumble dryer, microwave or near a naked flame.
