What does 2-in-1 stick vacuum mean?

It means that Polti Forzaspira D-Power has a double function: floor and portable vacuum cleaner. In fact with a simple click it turns into a practical portable vacuum cleaner: by connecting the mini turbo brush or the 2-in-1 suction lance, it is possible to remove dirt from small surfaces (upholstery, shelves, drawers, etc.)
