Those who bought the Dyson PencilWash in February may be feeling a bit let down. The company delayed the release of the model it should have launched initially by six months, and it is now being sold at the same price. The W1 PencilWash, which we tested, is already available from resellers for around 240 euros, offering buyers a choice: either purchase the newer model or save 100 euros for the original version. The W1 PencilWash builds on the design that made the first model popular. It features a 38 mm diameter handle, similar to Dyson’s Supersonic hair dryer and the PencilVac. The device uses a motorized head with a microfiber roller that self-dries with each rotation, without requiring washable filters. Clean water is stored in the head and continuously applied to the roller, while dirty water is collected in a separate compartment. The roller, with 64,000 to 84,000 filaments, is hydrated at twelve points instead of eight. Dyson claims the device leaves the floor "50% drier" behind it, though it doesn’t specify how this is measured. A detangling comb behind the roller is designed to handle hair up to 35 cm in length. The battery life has increased from 30 to 45 minutes, with a claimed coverage of 320 square meters in low hydration mode using a 290 ml water tank. This should be enough for an average apartment, unlike the first model, which required more frequent recharging. For homeowners with solar panels, the SolarFlow 2400 AC+ offers a way to store excess energy in batteries, compatible with most rooftop solar systems. While it is slightly heavier, it remains flat enough to fit under a couch. The press release mentions a "lighter and thinner" design, but technical specifications show a slight increase in weight and hand weight, attributed to a denser roller and a larger battery. Despite this, the W1 PencilWash remains significantly lighter than most competitors, which often weigh over 4 kg. It retains the 180° tilt and can fit under 75 mm height, which is a key advantage over some competitors that can’t fit under beds. The product comes with a charging station and storage stand, takes three hours and 30 minutes to fully charge, and includes a two-year warranty with parts available for three years. It also carries the LONGTIME label, a quality certification, like the three Nurovi robots launched on the same day. The W1 PencilWash is designed for hard floors and small spaces, making it unsuitable for carpets or large homes. It cannot replace a traditional vacuum for picking up large amounts of dry debris, despite Dyson’s claims about its debris pickup ability. It also does not self-clean on its charging station, requiring a weekly manual rinse of the roller. This reflects a trade-off in design, prioritizing precision over a larger water tank, similar to the PencilVac. The W1 arrives during a busy period for Dyson, as it launches products like a camera toothbrush and air purifiers for 2027. It is the only product in the range currently available for purchase. The W1 PencilWash is essentially the model the original should have been—offering the same price, addressing issues raised in the February test, and weighing just 200 grams more than a damp mop. The real question is whether Dyson originally planned to release two models within six months or if customer feedback was harsher than anticipated. Given the speed at which the company has introduced new products, the former seems more likely.
