The LCD screen displaying remaining run time.

Beginning your clean

Your machine constantly measures the microscopic particles being picked up. These are displayed in a graph, grouped into four colour-coded size ranges: Microscopic, Fine, Medium, Coarse.

Graph displaying Microscopic, Fine, Medium, and Coarse particle sizes.

How the bars work

The bars grow and shrink, in real time, based on the volume of particles being removed as you clean. So you know when to keep cleaning, and when your floor area is clean.

What the bars mean

In Auto mode
Blue bars: High volume, increased suction
White bars: Medium volume
Green bars: Low volume
In all other modes, white bars also represent a high volume of particles.

After your clean

At the end of your clean, the screen displays a summary of the particles that have been removed. Giving you scientific proof of a deep clean.

FAQs about the LCD screen

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 powered attachments, including the Digital Motorbar™ cleaner head, the Fluffy Optic™ cleaner head, and the Hair screw tool.

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

The bars on the graph will slow down and turn green to show that less debris is being picked up, letting you know your area is clean.

Power modes

Getting to know your power modes

Your Dyson Gen5detect™ has three power modes for different tasks. Simply change the power mode using a single button.

Auto mode

The optimum balance of power and run time. Attach your cleaner head or Hair screw tool to activate Auto mode. Suction power automatically adapts to dust levels.

Eco mode

Eco mode indicates the longest battery life of the three modes, giving you maximum run time for longer cleans all around your home.

The green Eco mode indicator.


Boost indicates the shortest battery life of the three modes. Designed for intensive spot cleaning of ground-in dirt.

The red Eco mode indicator.

Intelligent suction power

Dyson recommends auto mode for the best experience. Suction power automatically increases when higher concentrations of dust are detected. Once the dust is removed, power returns to normal to conserve the battery.

Cleaner heads

Getting to know your cleaner heads

Your Dyson Gen5detect™ vacuum is engineered to operate with two cleaner heads, for different floor surfaces.

  • Digital Motorbar™ cleaner head switching from a hard floor to a carpet.

    Digital Motorbar™ cleaner head

    The Digital Motorbar™ cleaner head's Dynamic Load Sensing technology intelligently adapts suction power to different floors, while in Auto mode. Hair removal vanes automatically de-tangle hair from the brush bar as you clean.

  • Fluffy Optic™ cleaner head illuminating dust on a hard floor.

    Fluffy Optic™ cleaner head

    New Fluffy Optic™ cleaner head illuminates the microscopic dust and dirt on hard floors. Anti-static carbon fibre filaments remove fine dust from hard floors and narrow gaps.

FAQs about cleaner heads

The blade of light is optimised to work on any smooth, hard floor – including white surfaces and wood laminate. Illumination is visible in most well-lit spaces. Direct sunlight (around 10,000+ lux) is not possible to outshine.


The de-tangling comb on the brush bar has 56 polycarbonate teeth to prevent tangling around the bristles. The comb is always in contact with the brush bar as it spins to prevent wrapping, so hair is sucked straight into the bin.
