FIELD: vacuum cleaners.

SUBSTANCE: inventions group relates to vacuum cleaners. The cleaning block comprises a columnar body part having a rotation direction hole formed on its outer circumferential surface, a shaft mounted to reciprocate a predetermined distance in its longitudinal direction in a cavity formed in the body part, a drive part that protrudes from the shaft in its radial direction, a brush part which has one side mounted on the outer circumferential surface of the body part in its longitudinal direction and rotates based on one side as a rotation axis, and a driven part which extends from the brush part in the direction to the driving part, passes through the rotation direction hole, and is inserted into the rotation direction groove formed in the driving part. The groove for the direction of rotation extends through a predetermined angle relative to the longitudinal direction of the shaft. When the shaft performs a reciprocating motion, the driven portion is guided to rotate by the rotation direction slot, and the brush is rotated by the rotation of the driven portion.

EFFECT: functionality is expanded, convenience of use is increased due to automatic adjustment of the position of the brush depending on the surface to be cleaned.
