Support for your Dyson V15 Detect™ vacuum

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.

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.

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.

A full charge takes up to 4.5 hours.

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

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

We recommend alternating your batteries regularly to prolong battery health.

Yes, the battery is designed to be left on charge, to ensure your vacuum is ready for the next use.

We recommend charging your machine after every clean to maximise run time.

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.

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.

Your machine does connect to the MyDyson™ app.
