Filter Cleaning
The filter should be cleaned often to
maintain peak Vac performance.
Cleaning A Dry Filter
NOTE: For best cleaning results due to
accumulated dust, clean the filter in an
open area. Cleaning SHOULD be done
outdoors and not in the living quarters.
1. Light cleaning of some dry debris from
the filter can be accomplished without
removing the filter from the Vac. Simply
slap your hand on top of the handle
while the Vac is turned off.
2. Remove filter from Vac. Gently tap the
filter against the inside wall of your dust
drum and the debris will loosen and fall.
3. For thorough cleaning of a dry filter
with fine dust (no debris) you may run
water through it as described under
"Cleaning A Wet Filter" Section.
