Abstract
Abstract Rotary brooms that are readily assembled at the point of use, each being formed by the combination of a casing, which can be multi-part, with a plurality of longitudinal members for supporting and guiding a group of individual brush segments of the broom. The longitudinal members can be mounted on the casing to provide a skew for the brush segments that they support, and have lateral tabs that are positionable to form guide shoulders for the supported brush segments.
