Litter on roadways has to be removed for hygiene and to reduce pollution, amongst other reasons. Therefore, the effective operation of street sweepers is important in the collection of solid waste. In this article, the effectiveness of gutter brushes of street sweepers in removing different debris types, namely medium-size gravel, small and fine particles, and wet thin debris is studied by means of sweeping tests using a brushing test rig. Two types of gutter brushes, cutting and F128, are tested under a variety of operating conditions. The experimental tests provide a means of identifying suitable ranges of brush penetration for the different debris types under defined operating parameters such as brush angle of attack, brush rotational speed, and sweeper velocity. These ranges may provide sufficiently high removal forces and avoid the occurrence of sweeping problems such as backward sweeping and inappropriate bristle-surface contact. Optimum operating parameters for the three debris types studied, as well as a mixture of all of them, are determined. Lastly, the results indicate that, as far as the sweeping effectiveness is concerned, the F128 brush is the preferred one for the cases studied.
