FIELD: mechanical engineering.
SUBSTANCE: apparatus has cyclone catcher casing equipped with inlet port and outlet port and adapted for creating vortex air flow from dust-laden air drawn into vacuum cleaner via inlet port. Chamber for collecting of dust separated from vortex flow is detachably attached to cyclone catcher casing. Unit equipped with grid-type part is arranged at casing outlet port and adapted to prevent dust from flowing back through outlet port of catcher casing. Said unit has first member of grid-type part equipped with support, which rests upon outlet port, second member of grid-type part detachably attached to lower opening of said first member and equipped with outer circumferential surface, and grid part, which defines channel in fluid communication with outlet port on outer circumferential surface of second member of said unit.
EFFECT: simplified cleaning and repair of grid-type part, convenient usage and handling of vacuum cleaner.
