DUAL BRUSH FLOOR SWEEPER ABSTRACT OF THE DISCLOSURE A floor sweeper has a pair of brush rollers 33, 38 which always contact the floor, each roller sweeping into its own dust pan. Each brush roller has different debris pickup characteristics, with one brush roller tending to be more efficient in picking up large debris and the other roller tending to be more efficient in picking up smaller debris. The illustrated embodiment discloses a front brush roller 33 of the off-center tufted type which rotates continuously toward its respective pan 9 during reciprocal sweeper translation, with a relatively high free- wheeling rotation in one direction of sweeper translation. The rear brush roller 38 is of the wire twist type and also rotates continuously toward its pan 10 during reciprocal sweeper translation, but with relatively low rolling rotation in one direction of sweeper movement. A deflector 23 having forward and rearward facing curved surfaces 24, 25 is disposed between the brush rollers and mounts the drive mechanism 30, 31 for the brush rollers.
