The price of the Dyson PencilWash dropped to its lowest price ever during Prime Day

Dyson PencilWash Cordless Hard Floor Cleaner On sale for $199.99 ($150 off) on Amazon. This is the lowest price yet for a powered wet mop that’s a cousin to the silly-but-cool mop. Dyson PencilVac Fluffycones empty

The PencilWash essentially takes the sleek design of the PencilVac and simplifies it into a single-purpose electric mop. It’s designed for all types of hard home floors, and its slim head and pivoting neck allow it to reach under furniture. Dyson claims you can get 30 minutes of cleaning time before you have to put it on the included charging dock, and the 300ml water tank is estimated to cover up to 1,000 square feet before needing a refill.

While the Pencil’s name is cute, and the mop certainly looks nimble, keep in mind that it weighs about five pounds (heavier than the PencilVac) before adding any water or cleaning solution to its reservoir. But the self-propelled brush should help push that heft around your space without feeling most of the weight in your hand—until you sweep the stairs.

$200 isn’t cheap for a single-purpose cleaning tool (not to mention its full price of $350), but the PencilWash costs much less than the $600 PencilVac Fluffycones. Jennifer Pattison Toohey, our smart home reviewer, called the PencilVac “the perfect companion for your robot vacuum.” The PencilWash is a companion to this companion.
