The Dyson PencilWash™ is a Dyson wet cleaning device that removes both dry and wet messes and dries quickly after use. It is extremely slim and lightweight, weighing only 380 g in hand, and moves on its own with the help of the motor in the roller nozzle.

Self-propelled and easy to use

A powerful motor spins the roller nozzle so that the device moves forward on its own. The slim, 38 mm handle and lightweight overall weight make steering effortless. The articulated neck helps navigate around obstacles with smooth and controlled movement.

Cleans wet and dry dirt simultaneously

The dense 64,000-fiber microfiber roller removes splashes, stains, and dry dirt in one pass. Continuous hygienic cleaning ensures the floor is always washed with clean water.

Even cleaning results over an area up to 100 m²⁴

The 300 ml clean water tank is enough to clean up to 500 standard-sized tiles.⁵ The tank is located at the bottom, which improves balance and makes the device lighter to handle.

Suitable for stubborn stains and tight spaces

MAX mode provides extra power for spot cleaning and removing tough stains. The 170° tilting, low-profile design easily reaches under low furniture.

After cleaning, floors dry within minutes.

Compact and easy to store

The charging dock and nozzle-attached drip tray make storage easier. The slim design fits even in small spaces.

Suitable for all hard floors

The device works on tiles, vinyl, laminate floors, and lacquered wood surfaces without clogging. Dirt is collected in the nozzle, preventing it from reaching the filter.
