CLEANING THE MOTORIZED FLOOR BRUSH
When your motorized floor brush needs cleaning or locks onto
an object, it automatically shuts down to prevent damage to your
lifetime belt. The indicator light will illuminate red warning you to
turn off the vacuum and clear blockage immediately. The light
will reset itself once blockage has been cleared and power has
been cycled on/off or vacuum has been locked in the upright
position.
1
Detach the motorized floor brush from the detachable
canister.
2
Inspect the opening underneath and the rotating brush.
If a build-up of debris is present, remove it. Carefully cut
anything wound around the rotating brush with scissors.
Avoid damaging or cutting the bristles. (Fig. 25)
