Abstract
A waste collector for a sewing machine uses first and second different collection boxes, the second of which has a larger diameter suction hose than the first. The box having the larger diameter suction hose is coupled to the blower motor only through the first box via an airflow path which is more restricted than that of the larger suction hose.
