Cleaning the pre-filter and fine dust
filter (Fig. 30–33)
Clean both filters thoroughly at least
once every 3 months.
When cleaning them, it is essential to
follow the steps in the order de-
scribed.
Remove the dust container.
Empty the dust container over a bin.
Turn the lid of the dust container bey-
ond the stop until the arrow tips are
aligned at the top a (Fig. 30).
Remove the pre-filter by pulling it up-
wards b (Fig. 30).
Twist the fine dust filter anti-clock-
wise by 10 180° turns. Use the re-
cesses to help you (Fig. 24).
You will hear an operating noise, which
is a normal part of how the Comfort-
Clean function works.
Twist the fine dust filter clockwise.
Use the recesses to help you (Fig.
31).
Remove the fine dust filter (Fig. 31).
Risk of damage caused by incor-
rect cleaning.
The fine dust filter can become dam-
aged and be less effective as a res-
ult.
Do not clean the fine dust filter with
water and avoid cleaning the inside.
Do not use pointed or sharp-edged
objects to clean the filter. Do not
brush the fine dust filter.
Hold the fine dust filter over a bin.
Empty the fine dust filter by carefully
tapping the rubberised lower edge.
Turn the fine dust filter slightly while
you do this to free the dirt from all of
the crevices.
Risk of damage caused by incor-
rect cleaning.
The pre-filter can become damaged
and be less effective as a result.
Do not clean the pre-filter with water.
Do not use pointed or sharp-edged
objects to clean the filter.

brush supplied or with a dry cloth.
After cleaning the fine dust filter and
pre-filter, reinsert the former into the
latter by pressing the round cap on
top of the fine dust filter down as far
as it will go.
To continue achieving the best pos-
sible cleaning results, replace the fine
dust filter (HX FSF-2) with a new one
after approx. 3 years.
Reinsert the pre-filter in the dust con-
tainer (Fig. 32).
To do this, line up the guides (arrows)
and turn the pre-filter back to its ori-
ginal position (Fig. 33).
