This Harper #23 Supersweep All-purpose Broom head features synthetic bristles that are split into several thinner bristles by a process known as "feathering." Feathered bristles will trap and pick up more dirt and dust than standard bristles, which saves you time by sweeping only once. The bristles on this broom are trimmed to 3-1/8"L and are ideal for dust and fine dirt on smooth surfaces. This broom works great on polished cement, wood, tile and linoleum floors in basements and shops. For indoor use only on dry surfaces.
