ABSTRACT:
The invention relates to a sweeper machine for floors and bounded surfaces, e.g. the floors of workshops and warehouses, courtyards, having engaged with the machine frame, a removable container for collecting the swept trash supported by pivotally-mounted guides engaged by swivel members extending in a crosswise direction to the machine's longitudinal axis and cooperating to define a small frame intervening sealingly between a suction assembly in the frame and a suction mouth of the container, and with snap-action hook-up elements provided between the frame and the pivotally-mounted guides and spring members projecting from the frame and acting by spring contact on the container.
