Abstract
A cleaning apparatus includes a dust collector detachably installed at a cleaning stick. The dust collector includes a cyclone unit to generate a cyclone stream and a dust collecting unit to collect foreign matter. In this structure, a dust collecting efficiency of the dust collector may be increased, and a load of a cleaning apparatus body may be reduced.

- at least one cyclone generating rib formed spirally about the outer circumference of the tube to direct air introduced radially outward from the tube through the inlet hole to form a cyclone air stream,
- wherein the cyclone space of the cyclone unit and the dust collecting space of the dust collecting unit are disposed inside a dust collector body, the dust collector body comprising an opening directly communicating with the cyclone space and the dust collecting space,
- wherein a dust collector cover is disposed to open and close the opening of the dust collector body such that the cyclone space and the dust collecting space are accessible through the opening when the dust collector cover is open, and
- wherein the prevention rib protrudes inwardly from the dust collector cover.
