This is a set of (2) bushings for a Bissell 28806 Perfect Sweep. Over time, the stock bushings can go bad and cause the roller to make increasing noise and eventually stop turning correctly.
These are made of a glass reinforced resin to never need replaced again. Installation is straightforward once the sweeper is opened up. Simply remove the old bushing and slide the replacement into the groove shown.
Standard shipping charges will apply to the rest of the world.
