Dyson PencilWash Review: Unleashing Efficiency in Compact Cleaning

In the world of home cleaning, Dyson has consistently pushed boundaries with innovative, albeit premium, appliances. Today, we delve into the Dyson PencilWash, an electric mop that stands out for its exceptionally compact and lightweight design. While its small stature might suggest compromises, Dyson assures us that core cleaning performance remains uncompromised. However, as is often the case with Dyson products, this convenience comes at a price. Join us as we explore what makes the PencilWash a compelling, yet significant, investment for your cleaning needs.

Dyson PencilWash: First Impressions, Specifications, and Pricing

The Dyson PencilWash arrives in a thoughtfully designed carton that, while minimalistic, provides all essential product information. Upon opening, you’ll immediately appreciate Dyson’s meticulous approach to packaging; each component is rationally arranged and securely protected. Unpacking is a swift process, taking mere moments to get to the core device.

The streamlined unboxing experience is partly due to the minimal number of accessories included. Alongside the three-part mop, you’ll find a charging station, a drip tray, and a set of instruction manuals. A dedicated Dyson detergent, often recommended for optimal performance, would have been a welcome addition to the package.

Dyson products are predominantly positioned in the premium segment, and the PencilWash is no exception. At the time of this review’s publication, the Dyson PencilWash is priced comparably to other high-end electric mops. Considering it’s a single-function mop, its initial value proposition, purely based on features versus price, appears to be moderate. Nevertheless, let’s examine the full technical specifications:

  • Type: Electric mop with microfiber brush roll
  • Tanks: Clean water: 300 ml | Dirty water: 340 ml
  • Battery: Run time: Up to 30 minutes (covers approximately 100 m²) | Charging time: 3.5 hours
  • Noise Level: Up to 74 dB
  • Additional Features: 3 operating modes, LED display
  • Dimensions: 115.5 × 26.7 × 19.8 cm (45.5 × 10.5 × 7.8 inches)
  • Weight: 2.1 kg (4.6 lbs)
  • Construction Materials: Aluminum and high-quality plastic

Design and Build Quality of the Dyson PencilWash

The immediate impression after unboxing the Dyson PencilWash is its striking lightness and compact size. This initial feeling is quickly reinforced by its excellent build quality, dominated by high-grade aluminum and matte plastic finishes.

The fit and finish are exceptional, characteristic of Dyson’s premium standards. The device boasts an aesthetically pleasing design that also promises ease of maintenance and cleanliness over time.

The handle of the Dyson PencilWash is ingeniously designed in two parts. The aluminum upper section houses all the controls and connects to the battery. Notably, water does not flow through this section; all water distribution occurs directly within the electric brush head. Controls include a power button, a mode selection button (Standard, MAX 1, and MAX 2), and a simple LED display with intuitive pictograms.

The second part of the handle integrates the battery, which can only be charged when attached to the main pole. Dyson has not provided an option for a spare battery or independent charging. An LED indicator on the battery casing provides status updates on its charge level.

Moving to the electric brush head of the Dyson PencilWash, it too maintains a compact form factor while prioritizing ease of use. The matte finish on areas prone to scratches is a thoughtful design choice. The hinge connecting the handle to the brush head operates smoothly, allowing for a wide range of motion.

Beneath the brush head, you’ll find the microfiber brush roll and guide rollers that facilitate effortless movement across floors. In typical Dyson fashion, any red-colored components are designed for easy removal. This allows the entire module to be separated into two main parts: the replaceable operational elements (brush, tanks) and the drive section. Further disassembly of the operational module reveals three distinct sections: the removable brush, the dirty water tank, and the clean water tank. The design incorporates guides for each element, making disassembly and reassembly intuitive and straightforward.

Thoughtful Docking and Charging Solutions

The PencilWash comes with two distinct docking solutions. The first is a drip tray for the electric brush head module. This is a simple, contoured piece of glossy plastic designed to securely hold the mop head, allowing you to store the device without worrying about wetting other surfaces.

The second is the main charging stand, which doubles as a sturdy base for the mop. The charger’s power adapter is integrated into the stand with a 1.8-meter (approximately 5.9 feet) cable. The design is highly user-friendly, requiring no precise alignment when docking the device. Additionally, rubberized feet ensure the base remains stable and won’t slide unintentionally.

User Experience: Effortless Cleaning with Dyson PencilWash

The Dyson PencilWash is designed for ultimate simplicity. Once assembled and charged, it’s ready for immediate use. This electric mop doesn’t require smartphone connectivity or complex setup procedures. While a companion app is available, its primary function is for device registration and accessing user manuals and maintenance guides.

To begin cleaning, simply assemble the mop, fill the clean water tank (optionally adding a low-foaming cleaning solution), switch on the device, select your desired power mode, and start mopping.

Mopping Performance: Delivering a Spotless Finish

For those who typically dread floor mopping, even with other electric mops, the Dyson PencilWash might just change your perspective. The moment you power it on and glide it across the floor, its remarkable lightness becomes apparent. Both the minimal weight of the device and the powerful drive of the electric brush (complemented by the guide rollers) create an experience where you feel like you’re simply walking across the room, effortlessly guiding the mop.

We also appreciate the overall height of the device and the flexibility of its handle connector. While the handle isn’t articulated (meaning you’ll need to pull the mop back slightly to clean deep under low-lying furniture), its inherent lightness once again plays a crucial role in maintaining maneuverability. The vertical, cylindrical design, without a separate grip, feels intuitive, mimicking traditional mopping but with added power assistance.

Overall mopping quality is highly positive, even for regular cleaning without prior vacuuming. The PencilWash handled both tiled and wooden surfaces with ease, leaving them noticeably clean. The device offers three operating modes: Standard (default), MAX 1, and MAX 2. The latter two modes deliver the same increased water distribution but differ in duration. MAX 1 (a quick press of the MAX button, indicated by a flashing icon) activates for a few seconds, while MAX 2 (holding the MAX button, indicated by a steady icon) provides up to 60 seconds of maximum water flow.

A point of caution when mopping: in MAX mode, the water dispensed can be quite substantial, potentially forming small puddles. It’s advisable to use this mode judiciously, especially on delicate wooden floors. Furthermore, the roller-based design may not always perfectly clean irregular surfaces or deep grout lines. Dyson recommends using their own detergents but does not strictly limit users to them. Any low-foaming cleaning solution can be used effectively.

Maintenance: Simple and User-Friendly

Given its straightforward design and separate charging station, the Dyson PencilWash does not feature an integrated self-cleaning system. However, disassembling the operational module takes only moments, making it incredibly easy to empty dirty water and clean the components. The drip tray assists in mess-free transport, and the brush roll and other parts can be rinsed under running water. It is essential to allow all components to dry completely before reassembly and subsequent use.

Battery Life and Charging Performance

Dyson states that the PencilWash can operate for up to 30 minutes on a single charge, theoretically allowing it to clean approximately 100 square meters (1076 sq ft) of floor space. In practical testing, the device comfortably handled cleaning approximately 40 square meters (430 sq ft) twice, with occasional use of the MAX modes and excluding areas occupied by furniture. Throughout these cleaning sessions, the PencilWash maintained sufficient battery power and had adequate reserves in both the clean and dirty water tanks. A full charge for the device takes approximately 4 hours.

Conclusion: Our Verdict on the Dyson PencilWash

The Dyson PencilWash truly stands out as one of the most user-friendly electric mops on the market. Its exceptional lightness, ergonomic design, and straightforward construction are its defining advantages, all while delivering commendable cleaning performance. These qualities make it particularly well-suited for smaller living spaces or areas requiring quick, regular cleaning, as it can be prepared for use and stored away in just minutes.

However, prospective buyers must be prepared for its premium price tag. At a similar cost, some competitors may offer multi-functional devices with additional features, though often at the expense of the unparalleled convenience and ergonomic design that the PencilWash provides. For those prioritizing a lightweight, highly maneuverable, and efficient dedicated electric mop, the Dyson PencilWash is a compelling choice, especially where space is at a premium.

Frequently Asked Questions (FAQ)


Is the Dyson PencilWash suitable for all floor types?

The Dyson PencilWash is highly effective on common sealed floor types, including tiles and wooden surfaces. However, its roller-based design might not perfectly clean deep grout lines or highly irregular floor textures. It is crucial to use the MAX water modes judiciously on sensitive floors like real wood to avoid excessive moisture.


Can I use any cleaning solution with the Dyson PencilWash?

While Dyson recommends its own branded detergents, the PencilWash is compatible with any low-foaming cleaning solution. It is essential to use a low-foaming product to prevent residue buildup and ensure optimal performance, as high-foaming solutions can interfere with the device’s water collection system.


How does the Dyson PencilWash handle pet hair and larger debris?

The Dyson PencilWash is primarily designed for mopping and cleaning liquid spills or light dirt. While it can pick up some fine dust or small debris embedded in wet messes, it is not a vacuum cleaner. For optimal results, especially in homes with pets, it is recommended to vacuum or sweep the floor beforehand to remove larger debris and pet hair before using the PencilWash for wet cleaning. This will prevent clogging and ensure a more thorough clean.
