Abstract
The invention relates to a rotary duster used to vacuum in hardly accessible places and unstable objects, with a mechanical system of rotational speed control, the device being able to be mounted to the hose of a vacuum cleaner. According to the invention, the device consists of a stator (A) and a rotor (B) which are coaxially assembled by means of a bearing (C), where the rotor (B) is provided, at the cylindrical end (B1) situated inside the stator (A) with an axial-type turbine (1), without central axle, the blades of which, directed towards the rotation axis, are integral with the interior circumference of the rotor (B), they being configured right from the body thereof, on the tapered portion (B2) situated outside the stator (A), the rotor (B) is provided with some brushes (2) with flexible bristles, made of electrostatic microfiber, and with suction slots (3), the entire mechanical speed control system (D) being mounted with an elastic sleeve on the stator (A), and a screw and spring mechanism exerting a variable pressure on the rotor (B).
