FIELD: process engineering.
SUBSTANCE: invention relates to construction and may be used for cleaning pipelines of depositions, particularly, sewers, etc. Proposed device comprises working tool composed of umbrella made up of rotary conical head articulated with blades to open them to pipe ID. Rearrangement of thrusts allow adjustment of blades to definite pipe ID while pipes aligned inside their lengthwise axis and set at 90 degrees clean pipe walls of deposition and dirt on forcing water therein to rotate the head with blades.
EFFECT: higher efficiency of cleaning, expanded operating performances.
