Dyson has just lifted the lid on another cleaning gadget, and this time it’s a take on the humble mop. The electronic Dyson PencilWash has a cleaning head at the bottom of a notably thin handle and a design manoeuvrable enough to fit into tight spaces.

Priced at £299.99 when it goes on sale on March 4, the PencilWash is relying on its ultramodern design and cleaning chops to get people to part with their cash and ditch their mop and bucket set up.

The wet cleaner, which just like a mop is only for use on hard flooring, weighs 2.2kg and can lie flat to 170 degrees to reach under low furniture such as cabinets. It comes shortly after the release of the similarly slim Dyson PencilVac.

“Unlike conventional wet and dry cleaners, the Dyson PencilWashTM has no filter that would trap dirt, breed bacteria, emit odours, and is difficult and unpleasant to clean,” Dyson said. “Its filter-free design removes the risk of sludge, blockages, or drop in performance, ensuring powerful and reliable cleaning every time.”

The mechanism underneath uses a high-density microfibre roller that Dyson says has 64,000 filaments per cm squared, which spins to tackle wet and dry dirt. An eight-point system ensures the roller remains freshly wet, a flow that the user can control, with a 360ml collection tank slurping up all the gunk.

Dyson says the 300ml clean water tank can clean up to 100 metres squared of flooring and the rechargeable battery lasts for 30 minutes. That means you should be able to mop up accidental spills with ease, or even blitz an entire floor of your house for the weekly spring clean without having to empty or recharge the PencilWash halfway through.

That said, I tested out Dyson’s WashG1 wet floor cleaner on its launch in 2024 and found the dirty tank filled up relatively quickly when cleaning all my downstairs floors, which is four rooms. The tank on that machine is 800ml with a 1 litre clean tank, so while the new PencilWash looks the part, you may find it fills up rather fast.

When you run out of battery, you’d have to make sure there isn’t another spillage to tackle, as Dyson says it takes three and a half hours to fully recharge the device.

“We’re keen on making machines smaller and lighter while dramatically improving performance,” said John Churchill, Chief Technology Officer at Dyson.

“PencilWash applies that thinking to wet cleaning: our slimmest, ultra‑light format that glides effortlessly and reaches where others can’t. Using hydration, agitation and extraction, it delivers a hygienic clean with fresh water only, supported by our filter‑free system. It brings the simplicity of a broom together with the precision and power from Dyson engineering.”
