A bumper is fixed to the frame of a dust mop so the bumper will engage stationary objects and prevent damage to the mop head on the mop frame. Dust mops are generally carried under a carrier, and the bumper is primarily needed only on the portion of the mop that extends from under the carrier; and, the bumper extends beyond the mop frame to protect the complete mop when the mop is run at an angle with respect to the direction of motion. Bumpers can be provided on each end of a mop frame. For the short reversible frame, the bumpers will be on opposite sides; for long nonreversible frames, the bumpers will be on the same side. A new mop head is attachable to the mop frame around the bumpers by having a plurality of flaps making up the top. The flaps can be fastened around the frame with the bumper in place on the frame.
