  • Brush head for cleaning surfaces
    Patent number: 5592710
    Abstract: The invention relates to a brush head for large machines for cleaning large objects like aircraft. The brush head (18) has a brush roller (58) motor-driven in a predetermined direction of rotation (130), bearing a crown (66) of flexible, centrifugally born bristles (104) and acting with the bristles (104) against a surface to be cleaned.
