Sealing washers and the base are loosely placed on a bronze cup, the upper end of which is pressed into the body. As a result, the body rotates freely relative to the base.

The base is made in the form of a hexagonal sleeve (turn key) with an external thread for connecting the devices to the working position. A rotation mechanism is mounted on the axis on top of the body, which includes a rocker arm, a return spring, a latch with a pin and a protective plastic cap.

The barrel of the "Rosa-2" device is connected to the body by a threaded connection. Replaceable nozzles are installed at the ends of the barrels on the thread, which allows you to change the flow of water and the intensity of the rain. The "Rosa-2" device is equipped with a mechanism that allows watering in a circle or a sector.

The apparatus rotates under the influence of a jet of water, which, when ejected from the nozzle, hits the rocker blade and turns it by 30-90°, twisting the return spring. The spring returns the rocker to the stop on the body. At the moment of hitting the stop, the body turns clockwise by an angle of 2-3°. The speed of rotation of the devices and the angle of the irrigated sector can be regulated.

The device "Rosa-2" is equipped with three nozzles for spraying water.
