Periodic Maintenance
NOTE:   Turn off the switch and unplug the electrical cord 
before periodic maintenance. Never operate the 
vacuum cleaner without the dustbag/Smartbox 
or fi lter assembly in place.
Brush Roll
The brush roll turns as it sweeps and combs the carpet pile. 
Remove hair and threads from the brush roll so it continues 
brushing the carpet. To maintain the most effi cient cleaning, 
the bristles must touch the carpet. 
Brush Roll Belt
The brush roll belt turns the brush roll to agitate, sweep, and 
comb the carpet pile. Check the belt regularly to be sure it is in 
good condition. Replace the belt if it stretches, cracks or loses 
tension. Cut away any hair or threads wound around the brush 
roll or the belt pulley because the buildup could cause the belt 
to rotate unevenly.

4.  Lift left end of brush roll.
5.  Remove and discard belt.
6.  Place new belt around motor shaft.

cap into base.
