the handheld vacuum.
Hold the dust cup over the trash. Pull back
on the yellow Empty button and pull up to
open the dust cup lid until it clicks and locks

MAINTENANCE
IMPORTANT: Unplug the vacuum before performing any maintenance.
CLEANING FILTERS
Regularly rinse and replace the filters to maintain your vacuum's suction power and to
maximize the effectiveness of Odor Neutralizer Technology. To prevent damage from cleaning
chemicals, rinse filters with cold water only. Do not use soap. Allow all filters to air-dry for at
least 24 hours before reinstalling them to prevent liquid from being drawn into electronic parts.
PRE-MOTOR FILTERS
The Pre-Motor Filters should be rinsed
every month. To remove the pre-motor
filters, detach the dust cup, then slide down
the Filter Access buttons on both sides of
the dust cup lid. Pull out the filter housing,
then lift out the Foam Filter. Next, remove
the Felt Filter by the pull tab. After the
filters have been rinsed and are completely
dry, insert the foam filter into the housing
first, then slide in the felt filter, and reinstall
the housing into the dust cup lid.
NOTE: The pre-motor filters should be replaced every 2.5 years. The post-motor filter should be replaced every 3 years.

The headlights will flash or turn red to

HEPA FILTER
The HEPA Filter should be rinsed every 6
months. To remove the HEPA filter, detach
the dust cup, then pull the Filter Release
tab on the handheld vacuum filter cover.
Remove the cover, then squeeze the side
tabs on the HEPA filter and lift it out. After
the filter has been rinsed and is completely
dry, reinsert it into the handheld vacuum,
then reattach the filter cover.
