A sweeper vehicle may have an automatic side broom strike pattern positioning system including a plurality of actuators (e.g., pneumatic, hydraulic, and/or powered leadscrew) and a plurality of sensors (e.g., inclinometers and position sensors). The strike pattern may be maintained at a desired position as the side broom moves to different positions in a range of movement between a fully extended position and a fully retracted position. The system may have an override feature by which a vehicle operator may interrupt the automatic side broom positioning to allow the vehicle operator to take direct control of one or more side brooms, including the broom deployment angle and broom pitch and roll to create desired strike patterns for the side brooms. Related methods are also described.

A roadway or pavement sweeper with multiple sweeping modes for the removal of debris from a swept surface may, in some embodiments, include a sweeper vehicle having a pair of side-brooms independently movable between a retracted and extended position for sweeping debris into an area therebetween and at least one material-transfer broom to sweep a portion of the debris accumulated between the side-brooms as the vehicle moves in its direction of travel. A fan-driven suction-inlet may be provided at or adjacent each side of the vehicle. The at least one material-transfer broom may rotate in a first or other direction to transfer debris for entrainment into a selected suction-inlet for transfer to a debris hopper. Other embodiments are also described.
