folding ears and faces turn robotic vacuum cleaners into pet helpers

ZakkaGyou designs Petokka decoration set for cleaning robots

Petokka is a decorative accessory designed for robotic vacuum cleaners, developed by Tokyo-based studio ZakkaGyou. The product consists of two main components, a face element and a pair of ears, that attach to existing cleaning robots, transforming their appearance into simplified animal-like figures, such as cats or dogs. The decoration does not alter the robot’s functionality but introduces a visual layer that interacts with the robot’s movement during operation.

As the robot moves through domestic spaces, the flexible ears bend when passing under furniture, and the face elements shift slightly when encountering obstacles. These responsive details are a direct result of the material and mechanical properties of the components rather than electronic modification. The design leverages the robot’s existing motion to produce subtle visual changes over the course of a cleaning cycle.

Petokka reflects customization trends in domestic appliances

The project by Studio ZakkaGyou reflects the widespread adoption of robotic vacuum cleaners, particularly round, autonomous models that have become a familiar presence in residential interiors. As these devices have shifted from utilitarian appliances to everyday household objects, customization and decoration have emerged as common user practices. Petokka responds to this trend by offering a standardized, non-invasive method of personalization.

The name Petokka derives from the Japanese term ペット化 (petto-ka), meaning ‘to make something into a pet,’ with a modified spelling to emphasize a playful tone. Users can select from different face designs or choose versions that resemble their own pets.

Petokka is produced primarily from PLA plastic, while the ears are made from natural rubber to allow repeated bending without damage. The packaging is designed to function as part of the overall concept, featuring folded thick paper with embossed facial features and attachment elements shaped like tails and paws. This approach ensures that the animal-like form is present both before and after the product is installed on a robot.
