Introducing the slimmest vacuum cleaner¹ – the 38mm Dyson PencilVac with the first four conical brush bar cleaner head that ejects even long hair
The revolutionary double conical brush bar glides effortlessly across the floor on its four cones, deep cleaning right to the edges

- Four conical FluffyconesTM cleaner head strips and ejects even long hair, preventing hair tangling around the brush bar. The cleaner head glides on a forward and rearward brush bar, each spinning in the opposite direction, meaning uniquely that cleaning is excellent both forwards and backwards while providing unparalleled cleaning right to the edges of the room
- The newly developed Dyson HyperdymiumTM 140k motor – Dyson’s smallest (at 28mm) and fastest vacuum motor – provides high suction for the Dyson PencilVacTM, giving remarkable cleaning as evidenced by the forward and rear-facing laser-like illumination
- New 22mm linear dust separation system captures 99.99% of particles as small as 0.3 microns⁴
- New dust compressing system uses air to compress dust to maximize the bin capacity, with a new syringe, no-touch bin ejection mechanism for hygienic bin emptying and shroud wiping in one stroke
- Our first connected cordless vacuum connects to the MyDysonTM app for additional battery information and filter maintenance guidance for an enhanced cleaning experience
Chicago, IL | May 21, 2025
Today, Dyson unveils the Dyson PencilVacTM, a lightweight cordless vacuum at only 38mm diameter that is packed full of new technology. It is the only vacuum with four fluffy cones to detangle long hair. The new FluffyconesTM cleaner head ejects even long hair from the brush bar as you clean – meaning no more cutting or pulling hair out of tangled brush bars.
The Dyson PencilVacTM has four cones in two brush bars, one behind the other, which rotate in opposite directions causing the cleaner head to float across the floor, uniquely cleaning perfectly both forwards and backwards as proven by the laser-like illumination both in front and behind. The cones project at the edges, giving unparalleled cleaning right to the skirting board. At just 1.8kg and 38mm in diameter, the Dyson PencilVacTM with its double brush bar is Dyson’s most maneuverable vacuum, cleaning perfectly backwards or sideways, right up to the edges – all with minimum effort.
“I have long wanted to make a vacuum of only 38mm diameter (the same as my latest hair dryer, the Supersonic rTM). But first we needed to develop our most powerful Hyperdymium motor at only 28mm diameter to achieve such a slender machine. Then a new dust separation and compaction system was developed. We have taken cleaner heads in a new direction with our four conical brush bars counter rotating, so that the head simply floats on the floor, giving excellent cleaning in any direction.”
James Dyson, Founder of Dyson

New Fluffycones cleaner head
Detangles long hair and cleans right to the edge
The new Dyson FluffyconesTM features four conical brush bars in two brush bars that ejects hair as it is picked up, preventing hair from wrapping and tangling around the brush bar. The nylon bristles are specifically angled to further encourage hair migration while lifting fine dust and debris from your floors.
The front brush bar cones rotate in one direction, while the rear ones in the opposite direction, cleaning brilliantly in all directions for added ease and efficiency. Laser-like illumination both forwards and behind reveal invisible dust on hard floors on both strokes while giving you visible proof that all dust has been removed.
Uniquely, it has been designed so the four fluffy brush bar cones protrude at the sides to clean right up to the edge, unlike any other cleaner.

The slimmest cordless vacuum
Powered by the new Dyson HyperdymiumTM 140k motor
The Dyson PencilVacTM is the slimmest vacuum1 at just 38mm in diameter, enabling it to clean in the narrowest gaps in the home. The new format also enables it to lay flat on the ground, flattening to just 95mm to clean under low furniture.
The smallest of powerful motors at 28mm diameter had to be developed to be small enough to fit into the 38mm handle, while being fast enough to generate powerful suction.
The result is the new HyperdymiumTM 140k motor – Dyson’s smallest and fastest vacuum motor to date – with a diameter of just 28mm2. In such a small package, every component had to be engineered to the micron to work more efficiently, for greater power density. It is 34% more power dense than its predecessor3, spinning at up to 140,000RPM to generate 55AW of powerful suction on the Dyson PencilVacTM.

New Dyson two-stage linear dust separation system
The Dyson PencilVacTM is the first Dyson vacuum to use a new filtration system that effectively separated dust and debris from the airflow without causing filters to clog or cleaning performance to decline.
The Dyson PencilVacTM features our new two-stage linear dust separation system which captures 99.99% of particles down to 0.3 microns⁴ so only cleaner air is expelled back into the home while ensuring there is no loss of suction, ensuring optimal performance with every clean. In addition, dust is compressed to maximise its bin capacity and reduce bin emptying frequency.

Dyson’s first connected cordless vacuum
Receive battery information and filter maintenance guidance for an enhanced cleaning experience
The Dyson PencilVacTM is our first cordless vacuum that connects to the MyDysonTM app, offering owners more control and convenience than ever before. Through the app, owners can access additional settings and get real time maintenance alerts, including when and how to clean the filter. It also provides step-by-step guidance on how to care for and get the most out of their Dyson vacuum. This enhances owners’ experience while ensuring optimal performance over time.
The Dyson PencilVacTM is also equipped with an LCD screen, displaying the power mode selected and remaining run time while cleaning.
“Engineering our smallest and fastest vacuum motor is no simple feat. It was more than miniaturizing every piece of technology. It is a precise integration of motor design, electronics, software, and hardware, all working together seamlessly. At Dyson, we reimagine what engineering can do by refusing to accept trade-offs. We are uncompromising in our approach, from innovation and engineering to manufacturing. From a new motor, a new paradigm in cleaner heads, to a new separation system, the Dyson PencilVacTM represents our most advanced engineering to date.”
John Churchill, Chief Technology Officer at Dyson
Other key features of the Dyson PencilVac include:
- New air-compressing bin design compresses dust as it is separated from the airflow in the bin so it holds five times more dust and debris6 than its 0.08L capacity
- New hygienic syringe bin ejection system plunges dirt deep into the bin while wiping the shroud clean in the same motion
- Swappable battery pack for up to 60-minutes of fade-free suction⁵
- Magnetic charging dock for quick and convenient grab-and-go access, with tool storage
Two precision-engineered tools:
o Rotating combi-crevice tool to clean up high, down low, and anywhere in between, including awkward gaps
o Conical hair screw tool for ejecting hair fast, for use on carpets, sofas, mattresses, and stairs
