How to Use: Dyson PencilWash Cleaner User Manual

Overview

The PencilWash Cleaner is a cordless wet floor cleaner designed to remove spills, stains, light debris, and dried-on dirt from hard floors. Its wet roller uses clean water from an integrated tank while collecting used water and debris in a separate waste tray at the cleaner head.

This machine is suited to everyday hard-floor cleaning and targeted spot cleaning. Standard mode handles routine messes, while two MAX settings provide additional cleaning support for stubborn stains and larger areas of dried-on dirt.

Detailed Description

The PencilWash Cleaner is made from three main machine components: the battery, the PencilWash wand, and the PencilWash cleaner head. The battery locks into the upper end of the wand, and the wand connects to the cleaner head for operation.

The cleaner head contains a removable cassette. This cassette houses the microfibre wet roller, clean water tank, and waste tray. During cleaning, the roller is supplied with clean water and collects liquid and debris from the floor. The waste tray keeps recovered dirt and used water at the base of the machine.

A removable drip tray is included for transporting and storing the cleaner head. Place the head in the tray immediately after use to help contain residual dirty water.

The control area includes a power button, a MAX button, and an LED screen. The screen shows operating information, including the selected cleaning mode and battery condition.

Safety

• Do not operate the cleaner with an empty clean water tank.
• Always keep water in the clean water tank while the machine is running.
• Turn the machine off before removing the cleaner head, cassette, roller, or waste tray.
• Keep water away from the cleaner-head neck and its wand connection. Water in this area can damage the electrical connection.
• Do not store the machine with dirty water, a full waste tray, or a dirty roller.
• Use only a non-foaming detergent or the recommended probiotic cleaning solution when adding cleaning solution to the tank.
• Follow the detergent manufacturer’s dilution instructions. Excessive or unsuitable cleaning solution may cause foaming or affect operation.
• Keep the cleaner head level when carrying it to a sink to reduce the risk of dirty-water spills.

Setup and Operation

Charging the machine

1. Push the battery into the top of the wand until it clicks and locks securely.
2. Place the wand on its charging dock.
3. Fully charge the battery before using the machine for the first time.
4. For storage, keep the wand on the charging dock and place the cleaner head in its drip tray.

Preparing the clean water tank

1. Hold the cleaner head level and upright.
2. Press and hold the red quick-release button, then slide the removable cassette out of the cleaner-head body.
3. Turn the cassette so the clean water tank cap faces upward.
4. Unscrew and remove the tank cap.
5. Fill the tank with water up to the MAX line. If adding cleaning solution, leave enough space so the combined liquid remains at or below the MAX line.
6. Optionally add 10 ml of a suitable probiotic cleaning solution or non-foaming detergent.
7. Refit the cap and tighten it securely.
8. Before first use, remove the roller and wet it thoroughly under running water. Squeeze out excess water, then reinstall the roller in the cassette.

Attaching the cleaner head

1. Slide the cassette back into the cleaner-head body.
2. Align the cassette rail with the rail inside the main body.
3. Push the cassette into place until it clicks securely.
4. Attach the wand to the cleaner head.

Cleaning controls and modes

1. Press the power button to start the PencilWash Cleaner.
2. Allow approximately 10 seconds for the roller to become fully hydrated.
3. Begin cleaning in Standard mode, which is the default setting.
4. For spot cleaning, press and release the MAX button once. MAX mode 1 runs for 5 seconds before returning to Standard mode.
5. For larger stains or dried-on dirt, press and hold the MAX button. MAX mode 2 runs for up to 60 seconds or until the button is released.

Move the machine slowly over spills and debris for better pickup. Use overlapping passes so that each area receives consistent roller contact. Use MAX mode selectively because it can consume clean water more quickly.

Stop cleaning when the clean water tank is low or the battery is depleted. Before continuing, empty the waste tray, refill the clean water tank, and recharge the wand as required. Never continue operating with an empty clean water tank.

LED screen indicators

• Solid orange: Battery level is low, approximately 5% to 10%.
• Blue blinking light: Battery is charging.
• Rapidly blinking orange light: Battery level is critical, below approximately 5%.
• Solid white light: A non-Dyson battery has been detected.
• Red light blinking for 5 seconds: Main body fault detected.

Cleaning and Maintenance

After every use

1. Turn off the machine.
2. Detach the cleaner head from the wand.
3. Place the cleaner head in the drip tray immediately to contain dirty water.
4. Carry the level cleaner head and drip tray to a sink.
5. Hold the head over the sink, remove it from the drip tray, and keep it level and upright.
6. Press and hold the red quick-release button, then slide the cassette out of the main body.
7. Remove the long red rectangular cover and empty the waste tray.

Washing the cleaner head

1. Disassemble the cleaner head into its removable components.
2. Wash the cleaner-head parts with water and a household antibacterial solution diluted according to the solution manufacturer’s instructions.
3. Do not immerse or wet the cleaner-head neck.
4. Wipe dirt and excess water from the main body, waste tray, and clean water tank with a cloth.
5. Leave the wet roller upright in a warm, well-ventilated location.
6. Allow the roller and washed parts to air-dry for at least 24 hours before reassembly.

Storage and roller care

Empty and clean the machine after every use rather than storing it with dirty water or a damp, dirty roller. Store the wand on its dock and the cleaner head in the drip tray. Keep the dock in a cool environment below 35°C to help preserve battery condition.

Replace the microfibre roller approximately every six months, adjusting the interval according to cleaning frequency and roller condition.

Troubleshooting

The machine will not start

• Check that the battery is clicked fully into the wand.
• Place the wand on the charging dock and allow it to charge.
• Check the LED screen for a critical battery indication.
• If the screen shows the main-body fault indication, stop using the machine and arrange service assistance.

The roller is not sufficiently wet

• Allow approximately 10 seconds after startup for the roller to hydrate.
• Check that the clean water tank contains water.
• Confirm that the tank cap is fitted securely.
• Remove, rinse, and thoroughly wet the roller if this is the first use or if it has dried during storage.

The machine stops during cleaning

• Check whether the battery has run down and recharge the wand.
• Check the clean water tank and refill it if necessary.
• Empty the waste tray before resuming operation.
• Do not operate the cleaner with an empty clean water tank.

Pickup performance has decreased

• Move the cleaner more slowly across spills and debris.
• Use overlapping cleaning passes.
• Use MAX mode for stubborn stains or dried-on dirt.
• Clean and fully dry the roller, cassette, tank, and waste tray.
• Replace a worn roller when routine cleaning no longer restores performance.

Pros & Cons

• Pros: Cordless operation, separate clean-water and waste handling, a removable washable cassette, targeted MAX settings, battery and fault indicators, and a dedicated drip tray for transport and storage.
• Cons: The roller requires thorough cleaning after use and at least 24 hours of drying. MAX operation uses clean water more quickly, and cleaning must stop when the tank is empty or the battery is depleted.
