Cleaning apparatus and fiber structure manufacturing apparatus

A fiber structure manufacturing apparatus, comprising:

• an accumulation unit including a belt on which a fiber-containing material is accumulated to form an accumulation;
• a forming unit disposed downstream relative to the accumulation unit in a transport direction of the accumulation, the forming unit including a pressure portion, the pressure portion applying a pressure to the accumulation to form a sheet-like object containing fiber;
• and
• a cleaning apparatus disposed below the pressure portion, the cleaning apparatus including
• a cleaning roller configured to rotate about a first rotation axis to clean the pressure portion to which paper dust is attached, the first rotation axis extending the first direction, the cleaning roller having a first area and a second area that is adjacent to the first area in the first direction and to which more paper dust is attached than to the first area, and
• a remover configured to rotate about a second rotation axis, the second rotation axis extending in a second direction different from the first direction, the remover being configured to come in contact with at least a portion of the second area to remove the paper dust from the second area.
