LCD screen
Getting to know your LCD screen
During cleaning, your LCD screen displays the power mode and remaining run time in a second-by-second countdown, which constantly updates in real time, according to 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.
FAQs about the particle count graph
The bars and numbers in the particle count graph will slow down to show that less debris is being picked up, letting you know you’ve achieved a deep clean.
The particle count is a scientific measurement of the debris in your bin. Each bar represents a different size of dust particle. The bars rise faster when more debris of that size is vacuumed.
Reactive suction power works with all cleaner heads, including the Dyson Laser Slim Fluffy™, Digital Motorbar™ cleaner head and High Torque cleaner heads, as well as the Dyson Hair screw tool.
In Auto mode, the motor – which controls suction power – intelligently reacts to the amount of dust detected to provide a deeper clean, automatically. More dust, more power. Adjusting the motor sensitivity in the settings menu affects how responsive your machine is to the level of dust detected. Set to ‘High’, and your machine will react more often, and provide more suction power, when a smaller concentration of dust is detected. Set to ‘Low’, and suction power will react less often, and to larger amounts of dust. To change the motor sensitivity, hold the selection button beneath the LCD screen to enter the settings menu. Then tap the button to scroll through to the motor sensitivity settings. Hold to select, then choose your preferred setting.
Yes. The graph works independently of the attachments, and can be used with all cleaner heads, tools and accessories.
To reset the particle count, either charge your machine (the count will reset after 30 minutes of charging) or remove the click-in battery for 15 seconds before replacing. The vacuum can be purged of any residual dust in the cleaner head or wand by activating suction away from any surface for 10 seconds.
Dyson DLS™ (Dynamic Load Sensor) technology senses when the floor type changes, by monitoring brush bar resistance while using the Digital Motorbar™cleaner head and High Torque cleaner head. The piezo sensor senses changes in dust levels, and works with any cleaner head.
While we can measure particles as small as 0.1 microns in the lab, it’s not yet possible to fit these measurement technologies into a vacuum cleaner. What we can't yet detect with our piezo sensor, we can filter out. Our HEPA filter media can capture 99.97% of particles down to 0.1 microns in size5.
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.
-
Your LCD screen also displays
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.
Maintenance alerts
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. Pull the trigger at any time to start vacuuming.
Select language
Choose your preferred language.
Alerts
Turn screen and audible maintenance alerts on/off.
Particle count
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.
Motor sensitivity
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.
Alerts and notifications
Battery empty
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.
Airways blocked
A blockage has been detected. Watch the animation to see which airways to check. Your machine will also pulse seven times to alert you.
Filter wash
Your filter needs cleaning. Follow the advice further down the page to wash your filter.
Boost advice
If you use Boost mode frequently, this message will appear, to help you conserve battery life.
Power modes
Getting to know your power modes
Your vacuum has three power modes, each designed for different tasks. Change power mode quickly by tapping the selection button.
-
Auto/Med mode
The optimum balance of power and run time. Med mode applies when a non-powered tool is attached. -
Eco mode
Maximum run time, for longer cleans all around your home. -
Boost mode
For the toughest tasks. Designed for quick, intensive cleaning of ground-in dirt.
Intelligent suction power
Dyson recommends Auto mode for the best experience. In Auto mode, suction power automatically increases when higher concentrations of dust are detected. Once the dust is removed, power returns to normal to conserve the battery.2
FAQs about power modes and LCD screen
Both modes provide the optimal balance of power and run time. Auto mode works with all cleaner heads and the Dyson Hair screw tool, and automatically adjusts suction power to match the level of dust detected. Med mode is displayed instead of Auto mode when non-powered tools are attached, e.g. the Crevice tool.
Hold the selection button to enter the settings menu. Hold the ‘Select language’ option to view the languages available. Tap the button to scroll through the list. When you reach your preferred language, hold the button to select. If you select the wrong language, release the button before the countdown ends. To confirm the language, hold the button until the countdown ends.
The LCD screen only uses up to 1.5 watts of power, which won't noticeably impact run time.

FAQs about cleaner heads
The laser is optimised to work on any smooth, hard floor – including white surfaces and wood laminate. The laser effect is visible in up to roughly 500 lux ambient light – about the same as a well-lit kitchen space. Direct sunlight is in the order of 10,000+ lux and not possible to outshine.
The human eye has evolved to be more sensitive to green light than any other colour, helping to enhance contrast and revealing more invisible dust6.
Yes. The laser is Class 1 – the safest there is in all conditions.
Yes. The laser can be turned on or off using a slide button on the cleaner head.
The laser can be wiped clean with a microfibre cloth.
It is not waterproof.
This is a hard floor only technology. The laser effect does not work on carpet, and would not be useful on the Digital Motorbar™ cleaner head.
No. The laser uses roughly 1W of electrical power, far too tiny to have a noticable impact on run time.

How to clean your vacuum
Cleaning removes dust build-up and helps optimise performance. The filter and brush bar in the Dyson Laser Slim Fluffy™ cleaner head can be washed, and the bin and tools wiped clean.
-
Why it's important to clean your filter regularly
The filter captures microscopic dust, which can accumulate and affect performance. Help maintain suction by washing the filter at least once a month, or more frequently if used heavily.
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. -
