ABSTRACT:
A hand-guided sweeping machine has a filter housing pivotally mounted to tilt about an axis to facilitate shaking the filter free of dust. The filter housing outlet is in sealing registry with the blower intake when the housing is lowered, and is moved out of sealing registry when the housing is raised. In the raised position, the filter housing covers the hopper opening so that debris from the filter housing will continue to fall into the hopper. A flap-like sealing arrangement surrounds the filter housing inlet to prevent dust from entering the internal mechanism of the sweeper.
