A modular street sweeper includes a pair of side brooms to sweep debris laterally inwardly from opposing sides of the sweeper and a pickup mechanism to convey the swept debris from the ground to a collection hopper. The pickup mechanism includes a conveyor module in which a main broom at a rear of the sweeper sweeps the debris forwardly onto a rotating conveyor and a vacuum module in which a vacuum head spans laterally across the sweeper in proximity to the ground and communicates with a fan to direct the swept debris into the hopper. The vacuum pick up module is interchangeable with the conveyor pickup module so that a single sweeper investment can perform both a spring function of sand collection with the conveyor and a fall function of leaf collection with the vacuum head.
