Ans: Specialty brooms come in distinct bristle patterns which can deliver better cleaning performance. Also, they have distinct stiffness and angles. These are of three types, namely, grout brushes which have an angular shaped pattern of bristles that can clean the cracks and crevices; high low brushes have angled bristles that can clean the corners where the walls and floor meet, especially in the gully and drains and tank brushes have 180-degree pattern of bristles that ensure uniformity while cleaning the curved surfaces.
