Filter care

The filters included with this vacuum are long life filters. To be
effective in minimizing dust recirculation, the filters MUST be
installed correctly and in good condition.

WARNING: Appropriate personal protective equipment
like dust mask and gloves should be used while handling
the filters.
To Remove Filters

and unplug cord from outlet.
2. Release canister latches 5
from canister. Place vacuum head on a level surface
upside down.
3. Turn each filter 9 counterclockwise by gripping it on the
plastic end cover as shown, and carefully remove from
head, ensuring debris does not fall into mounting hole.

mild soap and allow it to dry. Dispose of cloth in an
appropriate container.
5. Inspect filters for wear, tears or other damage.
nOTE: If there is any doubt on the condition of the filters
they MUST be replaced. DO NOT continue use if filters
are damaged.

WARNING: Never use compressed air or a brush to clean
filters, otherwise damage to the filter membrane will occur
which will allow dust to pass through the filter. If needed,
gently tap against a hard surface or rinse with room
temperature water and let air dry. Cleaning of the filters
is typically unnecessary, even if the filter is covered with
dust. The automatic filter cleaning system will maintain
maximum performance and continue to function. If visual
damage to the filter membrane exists, replace filters. Filters
typically last between six and twelve months depending
on use and care.
