Vacuum and Wash Hard Floors in One Pass
The Dyson W1 PencilWash combines the functions of a wet and dry vacuum cleaner and hard floor washer, allowing you to tackle different types of everyday mess without switching between several cleaning appliances.
It can pick up dry debris such as crumbs, dust and hair, while simultaneously washing the floor with its motorised microfibre roller. This makes it particularly useful for kitchens, dining areas and other parts of the home where dry debris and wet spills often occur together.
From dropped food and muddy footprints to spilled drinks and stubborn marks, the W1 PencilWash is designed to tackle a wide range of everyday messes in a single cleaning pass.
Powerful Motorised Microfibre Roller
At the heart of the Dyson W1 PencilWash is its high-density motorised microfibre roller, engineered to pick up debris while washing sealed hard floors.
The roller contains 84,000 microfibre filaments, which work through agitation and capillary action to lift and collect dirt from the floor. Durable nylon bristles integrated into the roller also help collect different types of hair, including wet hair.
The result is a floor cleaner designed to tackle the combination of dust, dirt, hair, spills and stains that a conventional dry vacuum cleaner cannot wash away.
50% Drier Floors
Washing a hard floor can sometimes leave behind excess water, streaks or water marks. The Dyson W1 PencilWash uses Dyson's most absorbent roller to help leave floors 50% drier¹.
As you clean, the roller is continually refreshed with clean water, while 12 hydration points distribute water evenly across its surface. This helps maintain consistent water distribution and cleaning performance as you move around the room.
The roller is designed to absorb dirty water and debris as it works, helping leave your hard floors with a cleaner and drier finish.
Clean Water for Every Pass
The Dyson W1 PencilWash is designed to continuously refresh its roller with clean water while you clean.
As the motorised roller rotates, dirty water and collected debris are removed from the roller. Fresh water is then distributed back across the roller through the 12 hydration points.
This means the cleaner isn't simply spreading the same dirty water across your floor. Instead, it continually washes the roller as you work, helping provide a consistent clean from the beginning of the room to the end.
Designed for Pet Hair and Wet Hair
Hair can be particularly difficult to manage when it becomes wet, but the Dyson W1 PencilWash is designed to collect dry and wet hair from sealed hard floors.
The microfibre roller incorporates durable nylon bristles to help lift and collect hair, while the anti-tangle comb is designed to manage long hair up to 35cm.
This makes the W1 particularly useful for households with pets or long hair, where hair can quickly accumulate around floors and become difficult to remove when mixed with spills or other debris.
Two Cleaning Modes
The Dyson W1 PencilWash gives you a choice of two cleaning modes, allowing you to adjust its performance according to the cleaning task.
Standard mode is designed for everyday cleaning, making it suitable for regular maintenance of sealed hard floors.
MAX mode provides additional cleaning performance when you need to tackle tougher stains, heavier dirt or more stubborn messes.
Having two modes means you can use the W1 for quick daily cleaning while having additional power available when a more intensive clean is required.
Up to 45 Minutes of Cordless Cleaning
The Dyson W1 PencilWash provides up to 45 minutes of run time, giving you the freedom to clean without being connected to a mains power socket.
Its cordless design makes it easy to move between rooms, while the self-propelled motion and motorised roller help guide the cleaner smoothly across the floor.
The combination of cordless operation and self-propelled movement makes the W1 particularly convenient for regular hard-floor cleaning, whether you're dealing with a quick spill or cleaning several rooms.
Slim, Lightweight and Easy to Control
Cleaning around table legs, chairs and furniture can be difficult with a bulky floor cleaner. The Dyson W1 PencilWash takes a slimmer approach, featuring an ultra-slim 38mm handle designed to provide comfortable control as you clean.
Its flexible steering allows you to move around obstacles more easily, while the self-propelled motion helps guide the cleaner across the floor.
The result is a floor cleaner designed to feel more controlled and manoeuvrable during everyday cleaning.
Clean Beneath Low Furniture
Dust and debris can easily accumulate underneath sofas, beds and other low furniture, where conventional floor cleaners may struggle to reach.
The Dyson W1 PencilWash features 180° true lie-flat capability and can reach spaces as low as 75mm when laid flat.
This allows you to clean further underneath low furniture while maintaining cleaning performance, helping you reach areas that might otherwise be overlooked.
Edge-to-Edge Cleaning
Dirt, crumbs and hair often collect around the edges of rooms, particularly alongside walls and skirting boards.
The Dyson W1 PencilWash features edge-to-edge cleaning, allowing the cleaning head to reach close to walls and skirting boards.
This helps minimise the strip of uncleaned floor that can sometimes be left around the perimeter of a room, making it easier to achieve a more consistent clean across the entire floor.
Filter-Free Wet and Dry Cleaning
The Dyson W1 PencilWash uses a hygienic filter-free system, helping simplify maintenance after cleaning.
Unlike some wet and dry floor cleaners, there is no dirty filter to remove and wash. The waste system is designed to help prevent the build-up of clogging sludge inside internal pipes, reducing the amount of maintenance required after use.
This is particularly useful if you're using the W1 regularly for everyday spills, hair and floor cleaning.
Separate Wet and Dry Waste
The W1 PencilWash uses an innovative waste system that separates wet and dry dirt after cleaning.
Fine dry debris is separated from dirty water, helping make the waste easier to dispose of. The dirty water tank and debris tray can be removed together in a single action, simplifying the emptying process after cleaning.
The entire waste system can be emptied in around 20 seconds, helping reduce the time spent cleaning the cleaner itself.
Easy Storage and Charging
When you've finished cleaning, the wand charging dock provides a convenient place to store and recharge the Dyson W1 PencilWash.
A clip-on drip tray helps keep the machine neatly stored between cleaning sessions, while the slimline design makes it easier to find a practical storage location.
Keeping the cleaner on its charging dock also means it's ready for the next spill, stain or everyday floor-cleaning job.
Designed for Sealed Hard Floors
The Dyson W1 PencilWash is specifically designed for sealed hard floors rather than carpets.
It's suitable for a variety of sealed hard flooring surfaces, including:
Tiles
Vinyl
Laminate
Sealed wooden floors
Other compatible sealed hard floor surfaces
The wet-cleaning system makes it particularly useful in kitchens, dining rooms, hallways, utility areas and other spaces where floors are regularly exposed to spills, food, dirt and everyday foot traffic.
Important: The W1 PencilWash is primarily a hard-floor wet and dry cleaner. If you need a vacuum for carpets as well as hard floors, a conventional Dyson cordless vacuum may be a better choice.
Is the Dyson W1 PencilWash Right for You?
The Dyson W1 PencilWash wet and dry vacuum cleaner is ideal if your home has predominantly sealed hard floors and you want to simplify your cleaning routine.
Rather than vacuuming first and then using a separate mop, the W1 is designed to pick up dry debris and wash the floor in one pass. Its motorised microfibre roller can tackle dust, crumbs, hair, spills and stains, while its clean-water system helps provide a consistent clean.
It's particularly well suited to:
Homes with mostly sealed hard floors
Busy kitchens and dining areas
Households with pets
Homes where hair is a common problem
Families dealing with frequent spills and food mess
Anyone wanting to combine vacuuming and mopping
Homes with low furniture requiring under-furniture cleaning
People looking for a slim, easy-to-control floor cleaner
With its 38mm ultra-slim handle, 84,000 microfibre filaments, 45-minute run time, self-propelled movement, 180° lie-flat capability and filter-free waste system, the Dyson W1 PencilWash is designed to make wet and dry hard-floor cleaning faster, more convenient and easier to manage.
If you want a Dyson wet and dry vacuum cleaner that can vacuum and wash sealed hard floors in one pass, the W1 PencilWash provides a versatile alternative to using separate vacuuming and mopping appliances.
