A hand-guided sweeper employing a rotary brush to propel debris into a detachable hopper, a blower to facilitate pickup of dust and a filter to remove dust prior to passing through the blower includes guides on the frame of the sweeper adapted to cooperate with projections on the sides of the hopper, permitting the hopper to be inserted and removed from the front of the sweeper without notable lifting and interference to the blower and filter.
