Lift the light cover straight up and off by squeezing the short sides and lifting. This will reveal two screws. Remove the screws and then flip the whole thing over. Use a screwdriver to release the catches on the sides near the ends of the roller brush. This will allow you to lift off the entire top cover. Now you have access to the belt and roller brush. Be sure to push the roller endcaps all the way back down before putting the top cover back in place. Voila!
