Description

Other wet and dry machines depend on dirty exhaust filters, Dyson's doesn't.

No Filters. Here’s Why
No Disgusting Odours

Trapped moisture can lead to mould growth and unpleasant smells.

No Bacteria Hot Spots

Sludge build-up creates the ideal conditions bacteria needs to thrive.

No Difficult Cleaning

The accumulation of dirt, hair and residue makes maintenance off-putting.

No Clogging Sludge

Drawn up through the machine, dirt clogs and restricts airflow over time.

The Hygienic Solution

The Dyson Clean+Wash Hygiene hard floor cleaner doesn’t rely on a filter. It powerfully removes wet and dry mess hygienically.

Check out the video:
Dyson Most Absorbent Roller. Self-cleans on Every Rotation.

84,000 microfibre filaments rapidly absorb every kind of mess, while a self-cleaning mechanism removes dirt and hair with every turn.

Grabs and Lifts Dry Debris

Densely packed filaments interlock to form microscopic hook-like structures. Lifting debris fram hard floors - no need to vacuum first.

Rapidly Washes Wet Spills

Spills and tough stains are quickly removed, while waste liquid is drawn up into the cleaner head with powerful copillary action.

Nylon Bristles Remove All Kinds of Hair

Hundreds of bristles are embedded along the roller. Agitating hairs on the floor's surface and picking them up - even when wet.

New Anti-tangle Comb Helps Prevent Tangling

Positioned behind the roller, an Anti-tangle comb helps prevent wrapping and tangling, even on long hair up to 35cm.

A New Hygienic System Keeps Waste at the Cleaner Head

No sludge. Water and debris are separated. No clogging pipes. No dirt drawn up through the machine.

Automatic Waste Separation

A tray for dry debris. A tank for dirty water. Easy and hygienic disposal.

Quick and Easy Maintenance

Remove the unit with a single action. Emptying takes just 20 seconds.[5]

Self-clean Cycle

Once docked, start the self-clean cycle. Flushes the system after every use.

Hot-air Drying Dock

Dries the roller with 85°C air. Prevents growth of bacteria and odours.

Lighter than any Other[6]

The lightest in-hand wet and dry cleaner, it's easier to manoeuvre all around the home.

Flattens to 113mm

A new lie-flat format reaches under furniture as low as 113mm, to clean where others can't.

Goes Right to The Edge

Triple-sided edge cleaning reaches right along skirting boards, where dust often hides.

Leaves Floors Dry in 60 Seconds

The ultra-absorbent roller removes residual water, for a streak-free finish that dries in just one minute.[3]

Four Power Modes

Switch between modes to tackle anything from hair and debris, to sticky spills and dried-on stains. Low mode uses less water for wider coverage. Use Max mode for the most stubborn dirt.

Cleaning Performance:
Dyson’s Hygienic Filter-free System

Cleans both dry and wet dirt without relying on an unhygienic filter. No bacteria or bad odours expelled.[1]

Lifts Dust and Debris Like a Vacuum[2]

Densely packed filaments interlock to form microscopic hook-like structures, grabbing and lifting dry debris from hard floors.

Rapidly Washes Spills and Stains

Powerfully removes wet spills and tough stains, harnessing capillary action to draw up waste liquid.

Powerful Motorised Brush Bar

A Dyson motor spins the brush bar at speed, to quickly and powerfully remove dirt from your floors.

Streak-free Finish[3]

Dyson most absorbent microfibre roller prevents water stains and streaking with 84,000 densely-packed filaments.

No Clogging Sludge

Located at the cleaner head, a new hygienic waste system means no dirt is drawn upwards through the machine.

Fast Dry Time

Leaves less than 1g of water per metre,[2] allowing floors to dry within 60 seconds.

Removes All Kinds of Hair – Even When Wet

Embedded with nylon bristles, the microfibre roller agitates all kinds of hair, including pet hair, on the floor’s surface – picking it up, even when wet.

Anti-tangles – Even on Long Hair

New Anti-tangle comb positioned behind the roller helps prevent wrapping and tangling, even on long hair up to 35cm.

Triple-sided Edge Cleaning

Cleans edges and corners with three different points of contact. Ensures a comprehensive whole-floor clean.

No Drop in Performance[4]

Because the Clean+Wash Hygiene hard floor cleaner doesn’t rely on suction, there’s no decline in pick-up power, even after five years.[4]

Self-cleaning Roller Always Washes with Clean Water

With each rotation, dirty water and debris are scraped from the roller before it’s evenly hydrated with clean water.

Maintenance: New Hygienic Waste System at the Cleaner Head

Engineered to keep waste at the base of the machine, so no dirt is drawn upwards. No clogging sludge. No filthy internal pipes to clean.

Separates Debris from Dirty Water

Dry and wet waste are separated automatically, for hygienic and easy disposal.

20 Seconds to Empty[5]

The dirty water tank and debris tray can be removed in a single action.

Self-clean Cycle with New Hot-air Drying Dock

Flushes the whole system before drying the roller with 85°C air to prevent growth of bacteria and odours.

Usability: The Lightest Weight in-hand[6]

Slimmer and easier to manoeuvre. Lighter than any other.[6]

New lie-flat Format

Flattens to 113mm to clean under low furniture, without losing performance.

Suitable For All Hard Floor Types

Ideal for tiles, vinyl, laminate and sealed wooden floors anywhere around the home.

Four Power Modes For Different Tasks

Easily switch between modes to tackle anything from hair and debris, to sticky spills and dried-on stains. Use Max mode for the most stubborn mess

Notes:

1 Comparisons based on design differences: vacuums with exhaust filters can release odors or microorganisms during use. Because Dyson machine has no exhaust filter, there is no re-emission from a filter. Tested against Staphylococcus Aureus and wet dog odour.

2 For use on hard floor only.

3 Tested externally at Intertek with a trained panel, participants used the machine on sealed wooden, tile, marble, and vinyl flooring types.

4 Compared to suction wet floor cleaners. Tested against a range of dry and wet debris simulating 5 years worth of use, self cleaning mode used as per manufacturers instructions. Pick up tested to Dyson internal method TM-100712.

5 Tested internally, average time for the participants to remove the debris tray from the cleaner head and tap out the dry debris.

6 Compared against top 5 brands globally, with top 3 dedicated floor washer models from those brands, from GFK, FEB, and Circana data from June 2024 to June 2025 tested internally to DTM021.
