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.

Getting to know your LCD screen
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

FAQs about the particle count graph
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.
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 advanced filtration captures 99.99% of particles as small as 0.3 microns.3
