Surface cleaning and engraving machine that operates via a vacuum jet process, designed for processing, particularly cleaning, abrasive removal, engraving, or stripping of coatings, graffiti, or other surface contaminants using abrasive or gentle blasting media on parts, workpieces or surfaces such as walls, pillars, fences, facades, profiles, floors, ceilings, doors, furniture, etc., made of stone, concrete, wood, metal, plastic, or glass, comprising a container, with three sub-containers (15.1, 15.2, and 15.3) with integrated components: - a suction head with a dry vacuum cleaner with a fine dust filter - a hopper located beneath the fine dust filter in the middle sub-container (15.2) with a closing device/flap, - a sieve situated below this, with a funnel-shaped storage container underneath for the blasting media or granulate, equipped with devices to prevent clogging of the granulate and a metering device with a dosing disc, which possesses various nozzles, and with adjacent air flow guidance in the lower sub-container (15.3), - a connection at the upper sub-container (15.1) at the level of the dip tube with the fine dust filter for a flexible suction hose and - a connection at the lower sub-container (15.3) below the metering device with adjacent air flow guidance for a flexible suction hose to the air flow guidance, a blasting hood with a blasting lance, featuring one, two, or several inspection windows, aids to facilitate engraving works in the form of movable and removable cover plates and connections for the flexible suction hose and the flexible exhaust hose, where the metering device is arranged in a circular, open-topped body, this body simultaneously forms the housing of the metering device and includes the dosing disc, the housing having indentations on its inner diameter, which are offset at 45 degrees on the housing of the dosing disc and correspond during appropriate rotation of the dosing disc and each selected nozzle has a connection to the air flow guidance and thus to the suction hose, characterised in that the fine dust filter is surrounded by a dip tube, arranged protruding into the upper sub-container, and that the indentations are ball indentations with corresponding, in respective cavities guided balls, which are pushable by a spring towards the outer edge of the dosing disc and correspond with the ball indentations and that at the centre of the dosing disc a rod with a gear is fixedly connected perpendicularly with this dosing disc and this gear is part of a simple gear drive and the gear drive has a connecting and control element (3.1) as an adjustment rod (3.1) up to the outer side of the lower sub-container (15.3) and outside the lower sub-container (15.3) a handwheel with nozzle size markings is arranged. -
