A suction apparatus includes a suction unit, a negative pressure detection unit, a suction abnormality determination unit, and a notification unit.

The negative pressure detection unit detects a negative pressure value in the suction unit whenever the suction unit suctions the merchandise. The suction abnormality determination unit determines that the suction unit is abnormal in a case where the detected negative pressure value is lower in negative pressure degree than a predetermined suction determination negative pressure value continuously by a predetermined number of times of determination or more. The notification unit provides a notification in a case where the suction unit is determined to be abnormal.
