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.
