Dyson finally did it. They made a dedicated floor washer that doesn’t rely on suction. If you’ve been following the floor care world at all, you know this is a massive pivot for a company that basically built its empire on the power of the vacuum. The Dyson WashG1 is a weird, sleek, and surprisingly heavy piece of machinery that aims to solve the one thing every other "wet-dry" vacuum struggles with: the disgusting sludge of hair and dirty water.
Most machines try to suck up everything—spilled cereal, milk, dust, dog hair—into one single tank. It’s gross. It smells. Cleaning the machine becomes a bigger chore than cleaning the floor. Dyson looked at that mess and said, "No thanks." Instead of a vacuum motor, they used counter-rotating rollers and a clever mechanical separation system.
Honestly, it’s a gamble. You’re paying a premium for a machine that technically doesn't "vacuum" in the traditional sense. But after seeing how it handles a kitchen disaster, you might not care about the technicalities.
Why the Dyson WashG1 Ditches Suction Entirely
It sounds counterintuitive. Why would a cleaning tech giant remove the vacuum? Most wet-dry cleaners, like the Tineco Floor One or the Roborock Dyad, use suction to pull water and debris into a recovery tank. This creates two problems. First, the air coming out of the machine can smell like a swamp if you don't clean it perfectly. Second, separating solid waste from liquid waste is a nightmare for the user.
The Dyson WashG1 uses two highly absorbent microfibre rollers that spin in opposite directions. As they move, they pick up wet and dry debris simultaneously. Dyson engineers implemented a system of "extraction plates" and "flickers." These plates squeeze the dirty water out of the rollers and into the waste tank, while the flickers—basically little combs—push the solid hair and crumbs into a removable tray.
It's mechanical. It's tactile. It's surprisingly quiet because there’s no roaring vacuum motor. Because there is no airflow involved, you aren't blowing allergens or odors back into the room. If you’ve ever used a traditional wet-dry vac on a spill involving eggs or milk, you know that the "stink" can linger in the internal tubes for weeks. Dyson’s design keeps the mess strictly to the rollers and the tanks.
Handling the Grime: Real World Performance
Let's talk about the 1-liter clean water tank. That’s enough to cover about 290 square meters, which is plenty for most homes. You have three levels of hydration, plus a "max" mode for those dried-on coffee stains or muddy paw prints that have been sitting by the back door for three hours.
You've probably seen the marketing videos where they clean up a giant bowl of ramen. It works. But in real life, you're mostly dealing with dust, hair, and the occasional sticky spill. The rollers stay constantly saturated with clean water, so you aren't just pushing a dirty rag around.
The maneuverability is classic Dyson. It has that swivel neck that feels like it’s on a gimbal. You can get around chair legs and under the edge of kitchen cabinets without breaking a sweat. However, the machine is heavy. At nearly 5kg when the tanks are full, you’re going to feel it in your forearm if you’re doing a whole-house deep clean. It's self-propelled, so it pulls itself forward, but pulling it back takes a bit of muscle.

The Maintenance Factor
Cleaning the cleaner is usually where these gadgets fail. If the maintenance takes 20 minutes, you might as well have used a bucket and a mop.
Dyson’s self-clean cycle is pretty robust. You dock it, hit the button, and it flushes the system with clean water. It takes about two and a half minutes. But here is the catch: it doesn't dry the rollers for you. Unlike some competitors that use hot air to dry the brush heads, Dyson expects you to take them out to air dry. This is a deliberate choice—adding a heater would make the dock huge and consume more energy— but it’s something you have to remember to do. If you leave wet rollers in a closed-off room, they will eventually smell.
The solid waste tray is the real star here. It’s a little plastic drawer that catches the hair and "bits." You just slide it out and dump it in the trash. No more fishing wet hair out of a dirty water tank with your bare hands.
Where the Dyson WashG1 Falls Short
It isn't perfect. No tool is.
First, the edge cleaning. While the rollers go pretty close to the wall, there is still a tiny gap where the gears and housing live. You might still need to wipe the very edge of your baseboards manually once in a while.
Then there’s the price. We have to address the elephant in the room. This is an expensive luxury appliance. You can buy a lot of mops and buckets for the price of one Dyson WashG1. You are paying for the engineering that prevents the "stinky vacuum" syndrome and the ease of the solid-liquid separation.
Also, it’s only for hard floors. Don't even think about bringing this near a rug. Because there is no suction, it can't "suck" water out of carpet fibers. It is strictly a tile, laminate, and wood floor specialist. If your home is 50% carpet, this is an expensive addition to an already crowded utility closet.
Comparing the Options: Who Is This For?
If you have a house full of kids and pets, your floors are basically a war zone. The WashG1 is for the person who wants to clean up a spilled bowl of cereal and milk in 30 seconds without having to touch the mess.
- The Busy Parent: Perfect for the constant spills. The separation of solids means you aren't clogging your sink with Cheerio mush.
- The Pet Owner: The "flickers" are surprisingly good at grabbing pet hair without it getting tangled deep in a vacuum's internal filter.
- The Tech Enthusiast: If you love the Dyson ecosystem and want the quietest, most "mechanical" clean possible, this is it.
If you live in a small apartment with mostly area rugs, honestly, stick to a stick vac and a spray mop. The WashG1 needs space to live and a bit of room to maneuver.
The Long-Term Reality of Floor Washing
People often ask about detergents. Dyson says you can use their specific solution or just plain tap water. Many users find that a tiny drop of a pH-neutral floor cleaner works fine, but you have to be careful about suds. Too many bubbles will confuse the sensors and potentially leak.
The battery life sits at around 35 minutes. That sounds short compared to a vacuum, but remember, you move slower when mopping. You’re covering the same ground more methodically. For most people, 35 minutes is enough to do the entire ground floor of a standard suburban home twice over.
Essential Steps for Success with the WashG1
To actually get your money's worth and keep the machine from becoming a $700 paperweight, follow these specific steps.
- Empty the dirty water tank immediately. Do not wait until tomorrow. Bacteria grows fast in warm, stagnant water, and even though Dyson has great seals, a full tank of "kitchen floor juice" is a ticking time bomb for odors.
- Check the flickers. Every few cleans, pull out the red flicker strips and rinse them. Hair can sometimes get trapped behind them, reducing their ability to "comb" the rollers.
- Use the right hydration level. Don't just blast "Max" mode on hardwood. Level 1 or 2 is usually plenty and prevents the wood from staying wet for too long. Save Max for the tile grout in the mudroom.
- Air dry is mandatory. When the self-clean cycle finishes, pop the rollers out. Stand them up on the dock’s dedicated pegs. This is the only way to ensure they stay fresh.
- Monitor the rollers. They are microfibre, and like any cloth, they will wear down eventually. Depending on how abrasive your tiles are, expect to replace them every 6 to 12 months for the best agitation.
The Dyson WashG1 represents a shift in how we think about "clean." It moves away from the "suck it all up" mentality and moves toward a more refined, mechanical scrubbing process. It’s a specialized tool for a specific problem. If that problem is a daily battle against sticky floors and wet messes, it might just be the most useful thing in your cleaning arsenal.
For those dealing with massive surface areas of tile or sealed wood, the time saved on "cleaning the machine" alone often justifies the entry price. It’s less about the power of the motor and more about the intelligence of the separation. When you can dump the liquid down the drain and the solids in the bin without gagging, you know the design team actually spent time using the product themselves.
That’s the real value here. It turns a disgusting task into a manageable, almost satisfying routine. Just remember to empty that tank. Your nose will thank you.
