ABSTRACT:
A dust collecting unit for a vacuum cleaner is provided. The dust collecting unit includes a dust separating chamber with an air inlet formed on an outer surface thereof and an air outlet formed on one side thereof, a main dust collecting chamber formed in the dust separating chamber for separating dust and dirt in a cyclonic fashion, an auxiliary dust collecting chamber formed at one side of the main dust collecting chamber, and a partition plate for partitioning the main dust collecting chamber. The dust collecting unit allows an amount of air sucked and the efficiency of collecting dust and dirt to be greatly increased.
