Description
Slim Cordless Floor Cleaning. Wet & Dry Mess Pickup. Just 2.4kg.
Make everyday hard-floor cleaning quicker and easier with the Dyson W1 PencilWash™ Cordless Wet & Dry Floor Cleaner – W1PENCILWASH. Designed around a remarkably slim 20cm-wide body, the PencilWash combines wet and dry floor cleaning with lightweight cordless manoeuvrability for busy kitchens, dining areas and hallways.
The dedicated wet roller head helps tackle suitable everyday spills, footprints, surface marks and grime while also dealing with loose floor debris. At just 2.4kg, the PencilWash is easy to guide around furniture and through tighter spaces where larger floor-cleaning machines can feel cumbersome.
With up to 45 minutes maximum cordless runtime, an included wand charging dock and a clip-on drip tray for managing residual moisture after cleaning, the W1 PencilWash is designed to make regular hard-floor maintenance straightforward.
Wet & Dry Everyday Floor Cleaning
The Dyson W1 PencilWash is designed to handle a mixture of suitable wet messes and everyday dry floor debris within one cordless floor-care appliance.
This makes it particularly useful in busy areas where different messes can appear throughout the day, including:
- Everyday crumbs and loose debris
- Drink spills and splashes
- Food-related floor messes
- Muddy or dirty footprints
- Sticky surface marks
- General hard-floor grime
Stubborn residue may require additional passes, and wet cleaning should only be carried out on flooring suitable for moisture.
Ultra-Slim 20cm-Wide Design
At approximately 20cm wide, the W1 PencilWash has a particularly slim footprint for a wet and dry floor cleaner.
Its narrow profile makes it easier to manoeuvre around tables, chairs and kitchen units while also helping the cleaner reach floor areas where larger machines can be awkward to position.
The compact width is especially useful in smaller kitchens, hallways, dining areas, flats and other tighter household spaces.
PencilWash™ Technology
The PencilWash design focuses on slim, precise and controlled floor cleaning.
Rather than relying on a wide and bulky floor-cleaning body, its narrow profile is designed to make movement around furniture and confined floor areas more manageable.
This makes the PencilWash particularly appealing for everyday spot cleaning as well as regular maintenance of busy hard-floor areas.
Dedicated Wet Roller Head
The included wet roller head provides direct contact with the floor surface to help wash away suitable spills, marks and everyday grime.
It's particularly useful where dry vacuuming alone isn't enough, such as after drink spills, muddy footprints or food-related floor messes.
The wet roller should be cleaned after use in accordance with Dyson's maintenance instructions and allowed to dry appropriately to help prevent residue and unwanted odours from developing.
Designed for Compatible Hard Floors
The PencilWash is best regarded as a hard-floor cleaning appliance. Wet cleaning should only be carried out on surfaces that are suitable for moisture.
This can include compatible sealed tiles, vinyl, laminate and sealed wood flooring where the flooring manufacturer permits damp or wet cleaning.
Do not use the wet roller on carpets, rugs, unsealed wood or moisture-sensitive flooring unless Dyson and the flooring manufacturer specifically confirm compatibility.
Lightweight 2.4kg Construction
Weighing approximately 2.4kg, the Dyson W1 PencilWash is designed to remain easy to manoeuvre during regular household cleaning.
The lightweight construction makes it convenient to move between rooms and easier to guide around everyday obstacles than many larger wet-floor cleaning machines.
Its combination of low weight and narrow dimensions is particularly useful for quick clean-ups where getting out a heavier floor-care appliance may feel unnecessary.
Up to 45 Minutes Cordless Runtime
The rechargeable battery provides a manufacturer-stated maximum runtime of up to 45 minutes, giving you freedom to clean without a trailing mains cable.
This provides useful flexibility for both quick daily clean-ups and longer multi-room floor-cleaning sessions.
Actual runtime varies according to cleaning conditions and how the appliance is being used.
Ideal for Busy Kitchens
Kitchens frequently experience several different types of floor mess at once, from crumbs and food debris to drink splashes, footprints and sticky marks.
The PencilWash's wet and dry cleaning capability makes it particularly well suited to these busy spaces, while its narrow 20cm design helps it manoeuvre around kitchen furniture and cabinetry.
Useful for Dining Areas & Hallways
Dining areas are another natural fit for the PencilWash, allowing you to tackle crumbs, drink spills and everyday floor marks without switching between multiple floor-cleaning appliances.
In hallways, the wet roller can help deal with suitable footprints and tracked-in surface dirt while the cordless design makes quick cleaning straightforward.
Wand Charging Dock Included
The supplied wand charging dock provides a dedicated location for storing and recharging the W1 PencilWash between cleaning sessions.
Combined with the cleaner's narrow profile, this provides a practical storage solution where cupboard or utility-room space may be limited.
Clip-On Drip Tray Included
A clip-on drip tray is also supplied to help manage residual moisture while the wet-cleaning components are stored after use.
The tray should be checked and cleaned regularly so that collected moisture or residue doesn't build up around the storage area.
Easy Wet-Cleaning Maintenance
As with any wet floor-cleaning appliance, routine maintenance is important after use.
The wet roller and other relevant wet-cleaning components should be emptied or cleaned according to Dyson's instructions and allowed to dry properly. This helps maintain cleaning performance while reducing residue and odour build-up.
Only water or cleaning solutions specifically approved by Dyson for the W1 PencilWash should be used. Avoid bleach, aggressive chemicals or excessively hot water unless specifically permitted by the manufacturer.
