Claim 0:
1. A cleaning system comprising:
a cleaning vehicle that travels along a predetermined travel path including a rail to clean the travel path; and
a maintenance facility provided at a maintenance stop position set on the travel path,
wherein the cleaning vehicle comprises:
a suction portion that sucks up dust on the travel path;
a storage portion that is disposed below the rail and stores the sucked up dust;
a discharge portion that discharges the dust stored in the storage portion to the outside; and
a travel mechanism, for traveling along the travel path, that is disposed above the rail,

wherein the maintenance facility comprises a dust collection portion that collects the dust discharged to the outside from the storage portion via the discharge portion of the cleaning vehicle stopped at the maintenance stop position,
wherein the suction portion comprises:
a suction port formed so as to open toward the travel path and connected to the storage portion;
an air flow generation portion that generates a suction air flow for sucking up the dust through the suction port; and
a filter,

wherein the discharge portion comprises a discharge port connected to the storage portion and the air flow generation portion shared with the suction portion,
wherein the storage portion and the filter are disposed on a suction flow path connecting the suction port and the air flow generation portion,
wherein the storage portion is provided in a region of the suction flow path on the suction port side relative to the filter,
wherein the discharge portion generates a discharge air flow that is an air flow that moves in a direction opposite to a direction in which the suction air flow is generated by the air flow generation, thereby discharging, from the discharge port, the dust that has been captured by the filter and is stored in the storage portion,
wherein the cleaning vehicle further comprises:
a body portion coupled to the travel mechanism;
a cover portion covering a top and lateral sides of the body portion; and
a pipe constituting a part of a discharge flow path between the discharge port and the air flow generation portion,

wherein the air flow generation portion, the filter, the storage portion, and a proximal end of the pipe are arranged in order from bottom to top inside the body portion, and
wherein at least a portion of the pipe extends along directions in which the cover portion extends such that the pipe extends in an area surrounding the body portion, and a distal end of the pipe serves as the discharge port.
