Dyson PencilWash: one-minute review

The Dyson PencilWash is a wet floor cleaner that’s a counterpart to the PencilVac launched last year. Unlike the PencilVac, the PencilWash isn't a vacuum. Instead, it’s essentially an electric mop with a soft roller that spins as water is dispensed onto it along eight points, and a squeegee that forces dirty water out of the roller into a storage tank.
