harjasto
Harjasto is a Finnish term that can refer to a few different things, primarily related to tools or objects with bristles or a brush-like structure. In its most common usage, harjasto refers to a brush or broom. This can encompass a wide variety of cleaning implements, from hand-held brushes used for dusting or scrubbing to larger floor brooms for sweeping. The specific type of harjasto would often be clarified by an adjective, such as "lattiaharjasto" for a floor broom or "astianharjasto" for a dish brush.
Beyond general cleaning tools, harjasto can also be used to describe the bristle-like parts of other objects.
