A cyclone-type dust-collecting apparatus for a vacuum cleaner comprises a cyclone body 20, dust-collecting receptacle 30, and a grill assembly 400. The cyclone body comprises an air inflow port 25 and an air outflow port (27, fig 9) and in operation an air vortex of dust-laden air is formed in the body. The dust-collecting receptacle is removably connected to the cyclone body for separating dust and dirt from the dust-laden air by the air vortex.. The grill assembly includes a first grill member 410, a second grill member 420, and a connection member 430. The grill assembly is disposed at the air outflow port of the cyclone body and prevents the reverse flow of the dust and dirt into the air outflow port of the cyclone body. The first grill member has a supporter 411 that is supported on the air outflow port of the cyclone body; a second grill member has a grill portion comprising a plurality of fine passage holes, through which the air flows to the air outflow port. These members are designed such that the first and second grill members are easily separable and connectable by a connection member, thereby to allow a user to easily remove the dirt collected in the grill portion of the second grill member by simply separating the second grill member from the connection member and washing the second grill member with water. The second grill member may also be fitted with a backflow prevention plate (443, fig 8) at its lower end.
