A cleaner of root heads from top remains contains in the longitudinal–vertical plane a console bearing element, arranged in the longitudinal-vertical plane as inclined one, at the end of which an active cleaning unit formed by two driving brushes is mounted. A reducer of the drive of the cleaning unit has a central shaft, at the lower console end of which an additional round brush formed by elastic rods looking like narrow flat loops of different length is installed. An additional brush is mounted on the shaft movably in the direction of the axis of the shaft and is connected therewith by a pressure spring. |
