Aria is a concept of a window vacuum cleaner, designed to be compact and maneuverable. Currently the market offers various versions of vacuum cleaners quite similar to each other, all sharing a technical tool-like aesthetic and bulky volumes. Our design prioritizes lightness and ergonomics, Aria is developed around its internal components, rearranged to minimize the bulk. The concept is the result of a holistic and rational approach to design, one that takes into account both performance and human behavior, with the aim of creating a human-centered product. Aria facilitates the user and manages to integrate discreetly itself into the domestic landscape, going from being a tool for cleaning the house to being a product that becomes part of the house.
