Cleaning the fine dust filter
The fine dust filter is equipped with a
self-cleaning function. When a specified
degree of soiling is reached, the va-
cuum cleaner switches off automatically
for approx. 20 seconds and carries out
a cleaning process. You will hear this
process running.
The ComfortClean button on the va-
cuum cleaner lights up yellow.
Starting the ComfortClean self-clean-
ing function manually (Fig. 30)
If you vacuum a large amount of dust in
one go, you should start the Comfort-
Clean self-cleaning function manually
either during a vacuuming pause or im-
mediately afterwards. This enables the
vacuum cleaner to achieve the very
best cleaning performance again
straight away.
 With the vacuum cleaner switched
on, press the ComfortClean button
for at least 2 seconds.
The vacuum cleaner is switched off
automatically for approx. 20 seconds
and a cleaning process is carried out
which results in operational noise.
The ComfortClean button on the va-
cuum cleaner lights up yellow.
The vacuum cleaner will then switch
back on automatically and will operate
with the previously selected power
level.
We also recommend emptying and
cleaning the fine dust container once or
twice a year (see "Fault resolution" –
"Cleaning the fine dust filter manually").

Changing the battery in the radio-
control handle (Fig. 31)
Change the battery approximately every
18 months. One 3 V battery (CR 2032)
is required.
The vacuum cleaner can still be used
when the battery has run out or if
there is no battery fitted.
 Switch the vacuum cleaner on using
the On/Off footswitch .
The suction power setting  will flash
in the vacuum cleaner display.
 Press the ComfortClean button on
the vacuum cleaner for at least four
seconds (Fig. 30).
The vacuum cleaner can continue to be
used in this way, but only at maximum
power.
 Undo the screw on the battery com-
partment cover using a cross-tip
screwdriver and then remove the
cover.
 Replace the battery with a new one,
making sure the polarity is correct.
 Replace the cover and tighten the
screw back up again.
 Dispose of the old battery in a muni-
cipal recycling facility.
