FIELD: process engineering.
SUBSTANCE: invention relates to appliances intended for hydrodynamic surface cleaning devices and can be used for cleaning ship hulls in fluid or gaseous media. Proposed tool incorporates a barrel, hydro-cavitation nozzle fitted on the barrel end, adjustable ejector fitted on the barrel opposite end, water feed hose, handle and support assembly. The barrel part, on the nozzle side, features a wedge-like bead decreasing towards the barrel end. The wedge faces accommodate scraper blade and drop. The scraper blade features widening recess made on extending part water jet to pass through. Aforesaid support represents an operator elbow support attached to the handle.
EFFECT: higher efficiency.
