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.

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.

  • LCD screen showing Auto/Med mode

    Auto/Med mode


    The optimum balance of power and run time. Med mode applies when a non-powered tool is attached.

  • LCD screen showing Eco mode

    Eco mode


    Maximum run time, for longer cleans all around your home.

  • LCD screen showing Boost mode

    Boost mode


    For the toughest tasks. Designed for quick, intensive cleaning of ground-in dirt.

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 dust.

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 Direct drive cleaner head.

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

We’ve re-engineered the Dyson High Torque 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.

    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.

FAQs about maintenance

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.
