A dust emission measuring system for a vacuum cleaner is provided to measure dust emission of the cleaner objectively by measuring temperature and pressure of internal air in a test chamber and measuring test particles contained in the air, using a particle measuring part. A dust emission measuring system for a vacuum cleaner(A) comprises a test chamber(10), and a test particle supply part(20). The test chamber measures dust emission of the vacuum cleaner. The test chamber includes a chamber body(11), a door, a discharging duct(13), and a particle measuring part(15). The particle measuring part, which is installed at the discharging duct, measures the test particle contained in the discharged air. The test particle supply part includes a table(21) supported by a supporter(21a), a roller(22), a driving part(23), a transfer block(24) having a groove part in which the test particle is filled, and a suction nozzle(26) connected with a suction hose(H) to suck the test particle. The test chamber includes a temperature measuring part(16) for measuring internal air temperature of the test chamber, and an air pressure measuring part(14) for measuring the pressure of the discharged air. The driving part includes a servo motor(23a), a screw(23b), and a block bracket(23c).
