The invention provides a storage subassembly for a hose of a dust collector. The hose can be conveniently stored in the storage subassembly. The dust collector comprises a head subassembly, a dust barrel and a plurality of hose storage subassembly bodies, wherein the head subassembly can be separated from or combined with the dust barrel; each hose storage subassembly body comprises a fixing seat and an elastic piece; each elastic piece is arranged on the corresponding fixing seat; and the fixing seats are arranged on the lower portion of the dust barrel. The storage subassembly for the hose of the dust collector is simple in structure and assembly; the elastic pieces are not required to be fixed by screws or pressing caps; and moreover, because the hose is stored on the bottom of the dust collector, the whole gravity of the dust collector is reduced; and when moving, the dust collector cannot topple over easily.
