WARNING
Always unplug the power cord from
an electrical outlet before performing
maintenance to the vacuum cleaner.
To maintain efficient cleaning, the brushroll
must be kept free of carpet fiber, string,
or hair build-up. If the brushroll is jammed,
unplug and turn vacuum cleaner over and
check brushroll for fiber and hair build-
up. Use scissors to remove any build-up
entangled around the brushroll. Cleaning
the brushroll periodically is recommended
for best performance.
