Dyson figured out how to make a tiny motor, and now he can’t stop miniaturizing his devices.

Dyson just announced the PencilWash, a motorized wet floor cleaner that’s about the same size as a regular manual mop. This isn’t the first time Dyson has shrunk a traditionally bulky device: the PencilWash is a sister product to the Dyson PencilVac FluffyCones, an almost impossibly compact cordless vacuum.

The downsizing trend began in a less immediately visible way, in Dyson’s hair care department. The brand had already disrupted the hair care market with its original Supersonic hairdryer, but for its professional-only Supersonic r, it has redesigned its inner workings to be much more streamlined and “powerful.”

Dyson then decided that if it could make a hair dryer 1.5 inches/3.8 cm in diameter, surely it could also make a vacuum cleaner 1.5 inches/3.8 cm in diameter. Incredibly, it was a success: all the internal components of the PencilVac have been grouped into a handle the same width as the Supersonic r. To achieve this, the brand had to design a Hyperdymium 140k motor with a tiny width of 1.1 inches / 2.8 cm.

The same technology powers the PencilWash. And who knows where it will happen next – Dyson is clearly on a shrinking spree, and it would be foolish to stop there.

“We want to make machines smaller and lighter while significantly improving their performance,” says John Churchill, Dyson’s technical director. “The PencilWash… combines the simplicity of a broom with the precision and power of Dyson engineering.”

Small size; big victory
