Dyson’s PencilWash cordless hard floor cleaner is on sale for $199.99 ($150 off) at Amazon. This is the lowest price yet for the powered wet mop that’s a cousin to the silly-sounding-but-awesome Dyson PencilVac Fluffycones vacuum. The PencilWash basically takes the sleek styling and design of the PencilVac and simplifies it into a single-purpose electric mop. It’s designed for all manner of hard home flooring, and its slim head and pivoting neck allow it to get low to reach underneath furniture.
