aintenance and care
Cleaning the pre-motor and post-motor HEPA media filter
1. Unplug the vacuum from electrical outlet.
2. The pre-motor filter protects the motor
from dirt particles. It is located in the
slide out tray underneath the dirt
container. If the filter becomes dirty, pull
out the tray, lift out the foam filter pad
and clean it.
NOTE: The pre-motor filter may be
hand washed in cold water with mild
detergent. Rinse well and air dry
thoroughly before replacing.
3. The post-motor HEPA media filter
assists in the filtration process to
return clean air to the room. It is
located behind the door on the side
of the vacuum. If the filter becomes
dirty, open the door, remove the filter
and replace.
NOTE: The post-motor filter is a
white, pleated HEPA media filter. This
filter is NOT washable and must be
replaced when it becomes dirty.
