Abstract
The present invention relates to a motor-sweeper for cleaning large surfaces such as streets or industrial facilities. In particular it refers to an apparatus for collecting garbage and debris from the ground to apply to a motor-sweeper, wherein the broom for collecting garbage always remains adherent to the ground and the space between the garbage conveyor assembly toward the collecting container and the broom, and between the broom and the container remains uniform despite the wear of the brooms. Thus, the cleaning capability is not lost and the machine efficiency is improved.
