When properly assembled, the brush roll should rotate freely between the two end
caps. Check the condition of the belt; change if necessary. Replace the brush roll, belt,
and bottom plate (see How To Replace A Worn Belt).

As the brush roll rotates, it sweeps and combs the carpet nap. Remove hair and threads
from the brush roll so it continues brushing the carpet nap. When the bristles of the
brush roll no longer touch a straight edge held across the bottom plate, the brush roll
is ineffective because the bristles no longer touch the carpet nap. To maintain the most
effective cleaning, use a new wood brush roll. Replace the brush strips on the chromed
steel brush roll.

New brush strips are supplied in sets of two, one long and one short. To replace,
remove bottom plate and belt (see How To Change Belt). Then, grasp center of brush
roll and lift to remove.
