Dyson has reimagined the cordless vacuum cleaner with its latest innovation that transforms the bulky cleaning appliance into something as slender as a pencil. The company's engineering breakthrough represents a fundamental shift in vacuum design philosophy, prioritizing ergonomics and user experience over traditional form factors.
Pencil-Thin Design Revolution
The PencilVac achieves an unprecedented 38mm diameter for its main body, housing the motor, dustbin, and filter within a handle that measures just 1.5 inches thick. This radical departure from Dyson's signature bulky designs results in a vacuum that weighs under four pounds and resembles a traditional broom more than a conventional vacuum cleaner. The uniform weight distribution eliminates the dumbbell-like balance issues that plague traditional vacuums, where heavy components at both ends create user fatigue during extended cleaning sessions.
Technical Specifications
| Feature | Specification |
|---|---|
| Body Diameter | 38mm (1.5 inches) |
| Weight | Under 4 pounds |
| Motor | Hyperdymium 140k, 28mm diameter |
| Motor Speed | 140,000 RPM |
| Suction Power | ~50 Air Watts |
| Battery Life | Up to 60 minutes |

Engineering Marvel: The 28mm Motor
At the heart of this innovation lies Dyson's smallest yet most powerful vacuum motor to date. The Hyperdymium 140k motor measures just 28mm in diameter while spinning at an impressive 140,000 RPM, delivering approximately 50 air watts of suction power. This represents a significant engineering achievement, as Dyson abandoned its traditional cyclone technology in favor of a direct suction approach to fit within the ultra-slim form factor. The motor development process, which began around 2021, required overcoming numerous challenges related to materials, magnetic field coils, and durability at such high rotational speeds.
Revolutionary Brush System Eliminates Hair Tangles
The PencilVac features a completely redesigned cleaning head with four fluffy conical brushes arranged on dual rotating bars that spin in opposite directions. This Fluffycones system represents a major advancement over traditional roller brushes, as the conical shape and specialized airflow design ensure hair moves from the center toward the edges where it slides off rather than tangling. The brushes combine carbon fiber and soft fabric materials to effectively capture and break apart hair clumps, achieving what Dyson claims is zero hair entanglement on the rollers.
Key Innovations
- Ultra-slim design: 38mm diameter integrates motor, dustbin, and filter
- Zero hair tangle: Conical brush system prevents hair entanglement
- Syringe-style emptying: Eliminates dust clouds during bin emptying
- Smart connectivity: First Dyson vacuum with app integration
- Air compression: Dustbin holds 5x its physical capacity
- Uniform weight distribution: Ergonomic design reduces user fatigue
Smart Features and Connectivity
This marks Dyson's first smart cordless vacuum, integrating with the MyDyson app for battery monitoring, settings adjustment, and maintenance alerts. The vacuum includes an LCD display showing battery information, power modes, and runtime estimates. Built-in green LED lights help users spot hidden dust and debris in darker areas, while a see-through window in the handle allows real-time observation of the suction process.
Innovative Dustbin Design
Despite its compact 80ml capacity, the dustbin incorporates air compression technology that allows it to hold up to five times its physical volume. The syringe-style emptying mechanism eliminates the dust clouds that typically accompany traditional vacuum emptying, requiring only a simple push-pull motion over a trash bin. An internal scraper blade ensures thorough removal of dust and hair from the metal mesh filter during emptying.
Battery Life and Charging
The PencilVac delivers up to 60 minutes of runtime on a single charge, with a magnetic charging dock that also holds a spare battery for extended cleaning sessions. The swappable battery system ensures users can continue cleaning without interruption, addressing one of the primary limitations of cordless vacuum cleaners.
