To provide equipment, a method and a vehicle for sweeping a pavement, which can bring about an appropriate suction state depending on sweeping conditions.

A partition plate 424 for partitioning an internal space of an inlet port 42 into a front space and a rear space is provided inside the inlet port 42, and constituted in a longitudinally oscillatable manner by a rotary actuator 425. When a sweeping vehicle travels at a high speed, a longitudinal distance (x) of an opening part is lengthened by moving the partition plate 424 forward to secure an action time when a suction force acts on one arbitrary point on a road surface. When the sweeping vehicle travels at a low speed, the partition plate 424 is moved backward because an action time when the suction force acts on one arbitrary point on a road surface can be secured even if the distance x is shortened. A decrease in opening area enables a reduction in the amount of air sucked in by the blower 20.
