Dyson Cordless vacuums: Getting to know the LCD screen

Userlevel 7
Badge +13

The LCD screen displays everything you need to know during each clean, including:

  • The selected power mode.
  • The number of particles being removed from the floor;
  • The remaining run time and any alerts. 

In this article we take a close look at each of the power modes and particle counter, providing a overview and description of each. 


Getting to know the power modes

Dyson’s latest Cordless vacuums, including the V12, V15 and Gen5 each have three power modes for different tasks. These are Auto, Eco and Boost - keep reading for a description of each.

Auto mode

The optimum balance of power and runtime - suction power automatically adapts to the dust level 

Auto mode - Icon

Eco mode

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

Eco mode - Icon

Boost mode

Boost has the shortest battery life of the three modes. It is designed for intensive spot cleaning of ground-in dirt.

Please note: 

  • An estimation of remaining runtime is displayed on the LCD screen.


Getting to know the particle counter

A piezo sensor counts the microscopic dust particles passing through the inlet thousands of times a second. This is converts the acoustic vibrations of picked-up particles into an electrical signal. This signal allows the machine to identify and display the particle count on the LCD screen.


Beginning your clean

The machine constantly measures the microscopic dust particles being picked up. These are displayed in a graph, grouped into four size ranges: 

  1. Microscopic (>10µm)
  2. Fine (>60/90µm)
  3. Medium (>180µm)
  4. Course (>500µm)


How the bars work

During cleaning, the bar situated next to each particle measurement will grow or shrink, based on the column of particles being removed. 


What the bars mean

In auto mode:

Blue bars indicate a high volume of particle detection and an increased suction rate.

White bars indicate a medium level of particle detection.

Green bars indicate a low level of particle detection. This shows that less debris is being picked up, letting you know your area is clean and that you may move to another. 

In Eco and Boost mode, white bars also represent a high level or particle detection.   


After the clean

At the end of the clean, the screen displays a summary of the particles that have been removed. 


Getting to know the particle sizes


>10µm - Particles the size of allergens and pollen

Pollen is commonly carried into homes on skin, hair, clothes, footwear and pets. Once inside, pollen grains and antigens accumulate in house dust, reaching a peak concentration long after pollination season.

With their microscopic size and jagged shape, pet allergens can easily stick to upholstered furniture, bedding and fabrics – and often stay in the home for months as house dust, even after the pet is gone.


>60/90µm - Particles the size of microscopic dust and skin flakes

Moulds measure up to 100µm and can be found around kitchens, windows, and other damp areas. Their spores can irritate the nose and throat, causing shortness of breath.


>180µm - Particles the size of dust mites and fine sand

House dust mites are one of the major indoor triggers for allergies and asthma. Each mite produces about 20 droppings a day, which continue to cause symptoms even after the mite has died.


>500µm - Particles the size of sugar and fleas

These larger, visible particles are trapped in the bin as soon as they enter the primary cyclone and metal mesh filter


LCD Screen - Example


The design and layout of your model may vary from the one shown in the image, but the information available through the screen will broadly remain the same.
