Abstract
A cyclone-type dust-collecting apparatus for a vacuum cleaner comprises a conically shaped grill assembly disposed at the air outflow port of a cyclone body. The grill assembly includes a grill portion and prevents reverse flow of dust and dirt from the cyclone body. The grill assembly members are easily separable to allow a user to easily remove the dirt collected in the grill portion by simply separating the second grill member from the connection member and washing the second grill member with water.
