Creating healthier homes: Unveiling the Dyson V15 Detect cordless vacuum with laser detect technology to reveal hidden dust

Dyson’s most powerful and intelligent vacuum yet, capable of detecting, removing, sizing and counting microscopic dust for scientific proof of a deep clean.

March 24, 2021


  • Creating a healthier home is now made easier, as today Dyson unveils a brand-new generation of cord-free vacuum cleaners, with the Dyson V15 Detect. Engineered to detect hidden dust as small as 10 microns, and equipped with an acoustic piezo sensor to enable scientific proof of what's been sucked up, these new Dyson technologies redefine deep cleaning at home.


    Developed by a team of 370 engineers globally, these latest vacuums use a Dyson Hyperdymium motor which generates up to 230 air watts of suction[1] and 5-stage filtration captures 99.99% of dust particles down to 0.3 microns[2] for a powerful deep clean. Part of an all-new range of Dyson vacuums that cover the different cleaning needs of every household, these machines help create healthier homes at a time when 60% of people are cleaning more than ever before[3]. A new range, including smaller, medium and larger sized vacuums will be available in the USA from March 24th, 2021.

“As engineers our job is to solve daily problems, and the past 12 months has created plenty of new ones with more time spent indoors” explains James Dyson, Chief Engineer and Founder. “We are all cleaning more frequently, trying to remove the additional house dust but desperate for peace of mind that our homes are truly clean.


Our latest vacuums use adapted laser technology to reveal hidden dust[4], integrating a diode laser into the cleaner head that is precisely positioned at a 1.5 degree angle, 7.3mm off the ground to create the best contrast between dust and floor. We don’t think detection is enough, so we remove and meticulously size and count the particles 15,000 times a second using an acoustic piezo sensor which converts vibrations into electrical signals, displaying precisely the size and number of particles sucked up on an LCD at the back of the vacuum.


The Dyson V15 is both powerful and intelligent, giving the ultimate reassurance – scientific proof of a healthier, cleaner home”.

  • Laser dust detection

    Dyson has engineered laser dust technology on the Fluffy cleaner head to ensure you are reassured that your home has been deep cleaned. Laser Dust Detection reveals the particles you cannot normally see with a precisely angled laser integrated into the cleaner head.[5]


    The idea came about when a Dyson Engineer noticed that airborne particles in their home glistened in the sun. They began to research how they could take this notion and apply it to the fine dust we cannot see in our home. The team experimented with laser lights in the lab to test how this could be achieved, and a new solution was born.


    Dyson engineers integrated a green laser diode – chosen for its ability to provide the best contrast – into the Slim Fluffy cleaner head, positioning it precisely at a 1.5 degree angle, 7.3mm off the ground. It means hidden dust on the floor surface that is otherwise invisible to the naked eye can be seen and removed.

    Understanding that now more than ever people want more hygienic homes, Dyson engineers set about developing a technology which enables the user to measure the dust it detects and then displays it on an LCD screen for real time scientific proof of a deep clean. [6]


    So, how does this work? An acoustic piezo sensor has been integrated into the vacuum. Carbon fibre filaments in the cleaner head pick up microscopic particles which are sized and counted up to 15,000 times a second. The dust enters the vacuum and hits the acoustic piezo sensor within the bin inlet with the tiny vibrations being converted to electrical signals. The dust size and quantity are shown on the in-built LCD screen, so the user can see how much dust the vacuum has removed, as well as the different sizes of particles and deliver scientific proof of a deep clean.


    The vacuums have been designed so that they automatically increase suction power when they come across a large amount of dust. This happens in auto mode, when the piezo sensor detects high concentrations of dust, and reactive suction power is triggered to automatically increase in power. When dust levels normalise, suction power is reduced to its previous level.

    Introducing a new anti-tangle Hair Screw: Dyson Engineers also looked to solve the problem of removing hair on the brush bar. This is often a challenge for many vacuums, despite claims to the contrary, so we have developed a new anti-tangle conical brush bar which spirals hair off and into the bin. This prevents the wrapping of hair around the brush bar. Designed for human and pet hair, our engineers delicately tweaked the precise angle of the bristles on the tool, to ensure the release force did not tangle the hair and tested the tool on multiple hair types.


    New anti-tangle High Torque cleaner head This is Dyson’s powerful V15 Detect High Torque cleaner head that prevents tangling. The cleaner head now has 56 polycarbonate teeth which looks like a comb. These small teeth prevent tangling around the bristles when you are cleaning, and automatically clears hair from the brush bar, so you don’t have to.
