A remarkably slim and lightweight wet floor cleaner built for quick daily maintenance on hard floors in smaller homes, but the lack of suction and self-cleaning means it complements a vacuum rather than replacing one.

What We Like

• Exceptionally light at 4.6 lbs with just 0.8 lbs felt in hand during use
• Filter-free hygienic design with separate clean and dirty water tanks
• Very quiet operation with no suction motor noise
• 170-degree lay-flat angle gets under most furniture easily
• The most affordable entry point into Dyson's wet floor range

What We Don't

• No self-cleaning mode, requires manual roller washing after every use
• Struggles with stubborn dried-on stains like mud and ketchup
• Cannot clean room edges effectively due to roller design
• Does not vacuum, won't pick up dry debris like crumbs or cereal

Dyson built a wet floor cleaner that weighs less than most bags of sugar. The PencilWash, launched in March 2026, tips the scales at 4.6 lbs total and puts just 0.8 lbs in your hand during use. The handle is 1.5 inches in diameter. It genuinely looks and feels like cleaning with a giant pencil, which, credit where it’s due, is a refreshing bit of honesty in the product naming department.

But here’s the catch. To get the weight that low, Dyson stripped out some things you might expect from a Dyson-branded floor cleaner. There’s no suction motor. No self-cleaning cycle. And edge cleaning is genuinely poor. Whether those trade-offs make sense depends entirely on what you need from this thing.

First Impressions

The PencilWash’s whole pitch is what it doesn’t weigh. Most floor cleaners have a moment where you heft the thing and register it as a piece of kit. This one you pick up with two fingers.

The 1.5-inch handle diameter is thinner than most broom handles. Dyson has gone all-in on the pencil concept, and the point of it is wrist fatigue: a wet cleaner you can hold like a broom rather than brace like a machine. Whether that trade is worth the small tanks is the question the rest of this review works through.

Build quality feels good despite the featherweight construction. The clean water tank (10 fl oz) and dirty water tank (12 fl oz) snap on and off without fuss. Both are small, visibly smaller than what you’d find on a Shark HydroVac or Dyson’s own WashG1. That’s intentional. Bigger tanks would ruin the weight advantage.

The roller is dense. Dyson puts 64,000 microfibre filaments on it, though note that’s the whole roller rather than a per-square-centimetre density, which is how these numbers often get misread. An 8-point precision hydration system wets the roller evenly, with two modes for different floor sensitivity. Sealed tile gets the full treatment. Sealed hardwood gets a lighter touch.

What It Does Well

On everyday messes across smooth sealed floors, the PencilWash is quietly brilliant.

Coffee drips, muddy footprints, kitchen grease from last night’s cooking, the sticky residue where a toddler dropped juice. Fresh spills and light grime come up on the first pass without drama. The roller agitates, the hydration system keeps things wet enough to dissolve the mess, and the dirty water tank collects what’s left behind.

It’s quiet too. Noticeably quieter than any wet-dry vacuum I’ve used. No suction motor means no turbine whine, just a soft hum from the roller. You could run it at 6am without waking anyone, which is genuinely useful if you’ve got kids who track breakfast across the kitchen before school.

Then there’s the 170-degree lay-flat capability. With just 6 inches of clearance needed, the PencilWash slides under beds, sofas, and low cabinets that most floor cleaners can’t reach. I got it under a mid-century sideboard that sits maybe 7 inches off the ground. My Dyson Clean+Wash Hygiene can’t get anywhere close. For anyone who actually cleans under furniture rather than pretending it doesn’t exist, this is a big deal.

And the weight factor compounds over time. Fifteen minutes into a cleaning session with a heavier machine, your arm and shoulder start complaining. Thirty minutes in, you’re done. The PencilWash at 0.8 lbs in hand removes that problem entirely. A whole ground floor followed by an upstairs is a realistic session rather than an endurance event.

What It Doesn’t Do

Let me be blunt. The PencilWash doesn’t vacuum.

No suction. Zero. It won’t pick up crumbs, dust bunnies, dried pasta, or anything else that’s just sitting on the floor as dry debris. You need to sweep or vacuum before you use this, or accept that your wet roller is going to push dry bits around rather than collect them.

For a machine at this price in 2026, that’s a notable omission. The Shark HydroVac Cordless Pro XL sits in the same price bracket and actually vacuums and mops simultaneously. Most competitors here do both.

Dyson’s argument is weight. Adding a suction motor adds weight, noise, and complexity. Fair enough. But it means you’re buying a single-purpose tool that handles only step two of a two-step process.

Edge cleaning is the other weak spot. The roller doesn’t reach flush against skirting boards or into corners. You’ll see a strip of maybe half an inch along every wall edge that the PencilWash just… misses. On dark tile it’s obvious. On lighter floors you might not notice, but the grime is still there.

Stubborn stains also give it trouble. Dried-on tomato sauce, old coffee rings, anything that’s had time to really bond with the floor surface. The roller agitates, but without suction pulling the loosened grime away, tougher messes sometimes smear rather than lift. A second pass helps. Sometimes a third. On really stubborn patches, I gave up and reached for a scrub brush.

The Self-Cleaning Gap

This is where the penny-pinching really stings.

The Dyson Clean+Wash Hygiene has a self-cleaning cycle with hot-air drying. So does the WashG1. You press a button, walk away, and the machine flushes and dries its own roller. Dead simple. Keeps everything hygienic between uses.

The PencilWash? Manual everything.

After each cleaning session, you need to remove the roller, rinse it under the tap, wring it out, and leave it to air dry. Same for the dirty water tank, which needs emptying and rinsing. If you don’t do this promptly, you get that damp-cloth smell within hours. Leave it overnight and you’re dealing with genuine mildew.

It’s a few minutes each time, assuming the roller comes out without a fight. That’s not terrible in isolation. But it’s every use, and the novelty of hand-washing a floor cleaner roller wears thin fast when rivals do it themselves in the dock.

Dyson probably cut self-clean to save weight and hit the price point. I get the engineering logic. But a floor cleaner at this price without self-clean in 2026 feels miserly when machines costing half as much include it.

Battery and Coverage

Thirty minutes of runtime and 1,076 square feet of coverage per tank fill. Those are Dyson’s numbers.

Higher moisture settings drain both the battery and the clean water tank faster, and the tanks are the real limiter here rather than the battery. On the wettest setting you’ll be refilling well before the charge runs out.

For context: 1,076 square feet covers a decent-sized flat or the ground floor of a typical semi-detached. If you’ve got a larger home, you’re refilling mid-clean. Not a deal-breaker, but worth knowing. Refilling takes about 30 seconds.

Charging is 3.5 hours from empty. No quick-charge option. No spare battery. If the battery dies mid-session, you’re waiting.

The tanks are filter-free, which is genuinely nice. No consumable filters to replace, no clogging to diagnose. One less thing to maintain. Given that Dyson already expects you to hand-wash the roller, at least they didn’t also saddle you with filter upkeep.

Who Is This Actually For?

Not everyone. And I don’t think Dyson would argue otherwise.

The PencilWash makes sense for studio flats and small apartments where storage space is tight and floors are all sealed hard surfaces. It’s brilliant as a supplementary cleaner in bigger homes, the thing you grab for a quick kitchen wipe-down after dinner rather than dragging out the full wet-dry setup.

Older users and anyone with limited grip strength or joint issues should pay attention. The 0.8 lbs in-hand weight and thin handle make it accessible in a way that 10+ lb floor cleaners simply aren’t. My mum has arthritis in both wrists. She can’t use my Clean+Wash Hygiene for more than five minutes. She used the PencilWash for twenty without complaint.

If you already own a decent vacuum or robot vac and just want something lightweight for wet maintenance between deep cleans, the PencilWash fills that gap well. Think of it as a powered mop replacement, not a floor cleaner replacement.

It’s not for families with kids who generate serious daily mess. It’s not for pet owners dealing with hair and tracked-in dirt. It’s not for anyone who wants a single machine to handle the whole job. For those situations, look at the Dyson Clean+Wash Hygiene or check our best wet-dry vacuums roundup for options that vacuum and mop together.

Verdict

The Dyson PencilWash is a fascinating exercise in subtraction. Strip away suction, self-cleaning, and large tanks, and what’s left is the lightest powered floor cleaner I’ve ever used. At 4.6 lbs and 0.8 lbs in hand, nothing else comes close to how effortless it feels.

On fresh spills and daily maintenance across sealed hard floors, it does a good job. Quietly. Under furniture. Without making your arm hurt.

But the 3.5 out of 5 rating reflects real gaps. No suction means sweeping or vacuuming first, always. No self-clean means hand-washing the roller after every session. Edge cleaning is poor. Stubborn stains need multiple passes or manual scrubbing. For Dyson’s asking price, those compromises are hard to ignore when competitors offer more for less.

Buy the PencilWash if you value lightness above everything else, if you need a quick wet-maintenance tool for a small space, or if heavier machines cause you physical discomfort. For everyone else, the Dyson Clean+Wash Hygiene adds self-clean and feels like the more complete package. And if you want one pass instead of two, the Shark HydroVac Cordless Pro XL vacuums and mops together for roughly the same money.

Niche product. Done well within that niche. Just make sure you’re in it.

The current HydroVac Cordless Pro XL, and the machine that carries the line on after the older WD and AW HydroVacs went out of stock. It does the thing this category exists for, vacuuming and mopping hard floors in one pass, and the two-tank layout plus a continuous self-cleaning cycle target the two complaints these machines usually attract. Shark does not publish runtime, weight or cleaning path, so those are left blank rather than guessed.

View on Amazon

What We Like

• Vacuums and mops in one pass rather than asking for two trips
• Two-tank design keeps clean water away from the dirty water it picks up
• Self-cleaning cycle runs continuously, so the roller is not left wet and dirty
• Antimicrobial brush roll is aimed at the smell these machines usually develop
• LED display reports battery, surface type and tank levels
• Ships with two brush rolls, two solution concentrates, a spare filter and a dock

What We Don't

• Solution concentrates are a consumable, so there is an ongoing cost
• Wet cleaners of this type are a hard-floor and area-rug tool, not a carpet vacuum
• Runtime, weight and cleaning path width are not published by Shark
