FAQs about the particle count graph

How do I know when I’ve achieved a deep clean?

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.

Why do some bars move higher or faster than others?

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.

Which cleaner heads and tools react to different levels of dust?

Reactive suction power works with all cleaner heads, including the Dyson Laser Slim Fluffy™, Digital Motorbar™ and Direct drive cleaner heads, and the Dyson Hair screw tool.

Why would I change the motor sensitivity? And how do I do that?

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.

Does the particle count graph work with all cleaner heads, tools and accessories?

Yes. The graph works independently of the attachments, and can be used with all cleaner heads, tools and accessories.

Can I reset the screen to see the dust levels in a different room?

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.

What’s the difference between Dyson DLS™ and what the piezo sensor is doing?

Dyson DLS™ (Dynamic Load Sensor) technology senses when the floor type changes, by monitoring brush bar resistance while using the Digital Motorbar™ cleaner head. The piezo sensor senses changes in dust levels, and works with any cleaner head.

Why can the vacuum filter down to 0.3/0.1 microns but only detect particles down to 10 microns?

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 size.

FAQs about power modes and LCD screen

What's the difference between Auto and Med mode?

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.

How do I change the screen’s language?

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.

Does the screen use up the battery?

The LCD screen only uses up to 1.5 watts of power, which won't noticeably impact run time.

FAQs about cleaner heads

Does the angled beam work across all floor types? What about lighting or sunlight?

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.

Why use a green light?

The human eye has evolved to be more sensitive to green light than any other colour, helping to enhance contrast and revealing more invisible dust.

Is the laser safe for children and pets?

Yes. The laser is Class 1 – the safest there is in all conditions.

Can I turn the laser on and off?

Yes. The laser can be turned on or off using a slide button on the cleaner head.

Do I need to provide any special care to maintain the laser's performance?

The laser can be wiped clean with a microfibre cloth.

Is the laser waterproof?

It is not waterproof.

Why is the laser only on the hard floor Dyson Laser Slim Fluffy™ cleaner head, not on cleaner heads engineered for carpets?

This is a hard floor only technology. The laser effect does not work on carpet, and would not be useful on the Direct drive cleaner head.

Will disabling the laser extend run time?

No. The laser uses roughly 1W of electrical power, far too tiny to have a noticable impact on run time.

What’s different about this Digital Motorbar™ cleaner head?

We’ve re-engineered the Dyson Digital Motorbar™ cleaner head to include anti-tangle technology. While it still powerfully sucks up dust and hair from all floors, we’ve added a de-tangling comb that automatically clears hair from the brush bar.

Dyson-engineered accessories

Our accessories add even greater versatility. Each can be attached to the wand for cleaning up high, or directly to your machine for handheld cleaning.

FAQs about the battery

How long does the battery take to fully charge?

A full charge takes up to 4.5 hours.

How will I know if the run time is getting low?

Run time is displayed on the LCD screen, and your machine will pulse three times to alert you if it's getting low.

Can I charge my batteries on and off my machine?

Yes, your swappable battery packs can be charged on or off your machine, on or off the dock.

What's the best way to use an additional battery?

We recommend alternating your batteries regularly to prolong battery health.

How to clean your filter

FAQs about maintenance

How will I know if there’s a blockage in my vacuum?

Your machine will pulse seven times to alert you if there’s a blockage. You can follow the animated guide on your LCD screen to clear it.

How often should I clean the filter?

The LCD screen on your machine will remind you when it's time to clean your filter. This will usually be around once a month, but may be more frequent if you use your machine more heavily. After cleaning the filter, always leave it to dry for at least 24 hours. You must ensure it's completely dry before refitting. We recommend following the cleaning instructions and cleaning by hand. The filter is not suitable for dishwasher use.

Does this vacuum connect to the Dyson Link app?

Your machine works independently and doesn't currently connect to the Dyson Link app.
