FIELD: personal use articles. ^ SUBSTANCE: suction brush for vacuum cleaner is proposed. This suction brush comprises an upper housing, a lower housing, a lifting plate, mounted between the upper and lower housings, which recognises a part of the cleaned surface, a lever made with the ability to turn around a turning shaft which is parallel to the lifting plate and a magnetic coil. The magnetic coil turns the lever in one direction when the cleaned surface is a solid floor and in the other direction when the cleaned surface is a carpet. The lower housing is contacted with the cleaned surface when the lifting plate is lowered, and separated from the cleaned surface when the lifting plate rises. ^ EFFECT: invention is aimed at creation of a brush for a vacuum cleaner, which can adjust automatically the distance between its lower surface, which comprises a suction opening, and a cleaned surface when the cleaned surface changes from a hard floor to carpet and vice versa. ^ 6 cl, 6 dwg |
