Abstract
A bristle broom is provided with a plurality of relatively flexible, soft bristles the ends of which form the majority of the broom's sweeping surface, and a smaller number of relatively inflexible, stiff bristles the ends of which form a small portion of the sweeping surface adjacent one end thereof. The stiff bristles improve the broom's sweeping efficiency in corners and edges or in removing stubborn dirt while the remainder of the bristles retain the conventional sweeping efficiency of flat bristle brooms.
