Grasp the brush on the left end and pull it up and to the left to slide it out from under the belt and remove it.
Clean the brush to remove all dirt and debris trapped in the bristles. Cut hair or strings trapped on the brush with a pair of scissors, and pull them off the brush.
Grasp the left end of the brush and slide the right end of the brush under the belt, locking both ends of the brush into the base of the vacuum. Lift the belt with the screwdriver to hold it up and slide the brush beneath it, if you removed it with a screwdriver. Use the hook to remove the belt on the pegs of the belt removal tool, if a belt removal tool was used. The belt will slide back into place over the brush.
Position the soleplate over the bottom of the vacuum, making sure the tabs on the soleplate and vacuum are aligned. Turn the three screws clockwise with a coin to secure it.
