Abstract

A multi cyclone vessel dust collecting apparatus comprises a first cyclone vessel for centrifugally separating contaminants from drawn in air; a plurality of a second cyclone vessels configured on the first cyclone vessel; and a contaminant collecting unit attached to a bottom portion of the first cyclone vessel. Each of a plurality of the second cyclone vessels are parallel to each other. The center axis line of air rotation movement of the second cyclone vessel is substantially perpendicular to that of the first cyclone vessel. The contaminants collecting unit comprises a body which can be used as a handle.
