A cordless stick-type vacuum cleaner for easily cleaning gaps of furniture and corners of floor: the nozzle can be switched from an I- to T-shape. The switching nozzle allows cleaning from the floor to gaps and corners without changing the nozzle. A house dust sensor removes up to 20 µm dust. Auto power control is activated in places with less dust, which makes to run last up to 30 min. Its slim shape allows it to be housed in a seven cm space, the width of most wall sockets in Japanese houses. Its elegant linear appearance allows it to be left out for easy use without creating a cluttered effect.
