The present invention relates to an arrangement for use in surface treatment. The arrangement includes at least two elongate operating members, the underside of the operating members either being formed to allow for surface treatment or having attached thereto material to facilitate surface treatment. The operating members are so mounted as to be capable of longitudinal movement, relative one to another. Drive means are provided which impart a longitudinal, reciprocal moment to each of the operating members. At least one handle or grip member is provided for use by an operator. On actuation, the drive means impart longitudinal, reciprocal moments to the elongate operating members, the undersides of which are applied to a surface to be treated. |
