First-ever Dyson mop goes on sale in UK with £599 price tag and promise to remove tough stains and dry floors

Dyson says floors should be left with "a barefoot clean feel" after one pass of the Wash G1 — no more needing to fence off the kitchen while you wait for the floor to dry after it's been mopped.

Because of the efficiencies in the design, Dyson says 1 litre of clean water is enough to clean flooring up to 290m2. For context, the average total floor area of homes in the UK, as measured by the UK Government housing survey in 2018 was 94m2 — meaning you'd be able to clean every floor in your home 3x before you'd need to refill the clean water reservoir in the Dyson Wash G1.

Dyson announced its all-new Wash G1 cleaner back in May, but didn't confirm a release date at the time. For the first time, this £599.99 wet floor cleaner is now available to buy in the UK.

The announcement of the Wash G1 wet floor cleaner comes a few months after Dyson launched its latest vacuum cleaner, the V15 Submarine, which has a mop-like attachment that scrubs and dries floors. This attachment only works with the latest generation of vacuum cleaners — you won't be able to use it with your existing model.

If you don't want to upgrade your vacuum to be able to mop as well as vacuum, the Wash G1 seems like the obvious solution. Although, with a price tag of £599.99, it's not much of a saving compared to the £799 cost of the Dyson V15 Detect Submarine with its mop-like attachment.

Speaking about the Wash G1, Vice President of Dyson Home Engineering, Charlie Park said: "Most of us vacuum our homes regularly. But whilst wet cleaning is considered a necessary chore globally, many of us don’t know why we do it beyond the vague notion of hygiene.

"In fact, cleaning with water is essential to rehydrate and remove tough, dried-on stains.

"Over the years, a vast array of wet floor cleaning formats have emerged to help us tackle this chore yet users’ expectations are often left unfulfilled when it comes to stain removal, pick-up performance and floor finish. Dyson engineers solve the problems others ignore and we thrive on the challenge of creating better technology. The Dyson Wash G1 is the result of this; our first dedicated wet machine to wash hard floors, properly and hygienically."

Dyson has engineered the Wash G1 to distribute water evenly across 26 points positioned along the full width of each of the two microfibre rollers built into the head of the floor cleaner. These microfibre rollers are designed to absorb spillages as quickly as possible, while the 64,800 filaments per cm2 built into the rollerheads tackle dried-on stains, dirt and other debris on the floor.

With two rollers at the front and back of the machine — each independently driven by two motors inside the rollers, spinning in opposite directions so they clean in both directions — Dyson says its design will reduce the dwell time needed with each pass to lift stubborn stains and spills.

Everything your Dyson Wash G1 picks up will be passed through a 500-micron mesh, which separates the dirty water from larger debris, like crumbs or dust bunnies. Dirty water is collected in a 0.8-litre tank that can be poured down the sink.

The mesh filter stops large debris from passing into the machine and damaging any internal components. Dyson says trapping debris in the head makes for easier disposal too.

The engineers at Dyson specifically designed the internal components without sharp internal surfaces or crevices, to remove opportunities for dirt and grime build-up inside the machine. Not only that, but both the clean water and dirty water tanks were designed with large openings for easy maintenance and cleaning.

Borrowing from the innovations devised by its vacuum cleaner division, Dyson has used its omni-glide casters to offer extra balance and weight support, whilst the low head height allows for easy reach under furniture.

After use, the Wash G1 has a self-cleaning mode that saturates both rollers with clean water on the highest boost setting, flushing the entire system in preparation for the next clean. Just like its best-selling range of cordless vacuum cleaners, Dyson has created a charging stand for the Wash G1 that stores and refills the battery of the wet floor cleaner.

“Stain removal performance is dependent on the correlation of hydration of the floor and agitation applied. We’ve engineered our machine to allow owners full control, enabling them to deep clean their homes effectively," added Dyson's Charlie Park.

It's been a busy few months for Dyson, which recently took the wraps off the first update to its Supersonic hair dryer since it launched in the UK eight years ago, a radical redesign only sold to professional hair stylists, a new iPhone app that visualises exactly where you've cleaned — and what spots you've missed, as well as its first dedicated over-hear headphones, dubbed the Dyson OnTrac.
