A complete everyday kit
The concept is organised around the tasks people recognise: floor, upholstery, corners, and car. The purpose is not a feature race, but a clear relationship between each tool and a familiar routine.
CLEAN · Cordless stick vacuum concept

Design principles
The concept is organised around the tasks people recognise: floor, upholstery, corners, and car. The purpose is not a feature race, but a clear relationship between each tool and a familiar routine.
Battery, bin, filter, and tools are treated as visible parts of the product experience. The design language makes care and storage feel like part of the object, not an afterthought.
Flow S1 is a dry-cleaning concept within the KOVA CLEAN architecture. Its form is designed to sit alongside the different cleaning rhythms of a home, with a calm, compact presence.
