Maintenance and Cleaning

Be sure that the appliance is turned off and that
the mains plug has been removed from the
socket before performing maintenance or cleaning.
Changing the Paper Filter
The paper filter must be replaced if the window on
the filter replacement indicator is completely red
when the appliance is operating at maximum power
and the nozzle is raised from the floor.
The paper filter should be replaced even if it does
not appear to be full because fine dust can block
the pores in the surface of the filter.
The cover can be opened by pressing the button
and folding back until it locks.
*depending on model
Hygiene filter replacement: When removing the full
filter bag, pull the closing tab to automatically close
the bag. During this process you must overcome
slight resistance when pulling the tab. Full dust bags
with normal household dust may be disposed of
with household rubbish.
Insert the new paper filter in the guide rails and
slide down to the lower stop (note marking), only
then can the lid be closed. If a paper filter is not
placed in the appliance, the lid cannot be closed.
Please do not use force!
Changing the Microfilter
We recommend replacing the microfilter on every
fifth paper filter replacement, at the latest when the
dust level indicator is completely red with a clean
dust bag and the nozzle raised.
Open the lid and fold back until it locks. Remove the
used microfilter (Figure) by the tab and dispose of
with household rubbish. Insert the new microfilter.
Motor Protection Filter
The motor protection filter is a permanent filter and
does not have to be regularly replaced. The only
exception is if the paper filter has been damaged
and the motor protection filter soiled: remove the
motor protection filter, clean (only tap out) and refit.
Insert new paper filter.
HEPA filter
A highly effective special filter belonging to Class
"S". This filter offers relief and assistance to allergy
sufferers. The HEPA filter should be replaced after
one year.
Cleaning
Use a damp cloth to wipe off the housing and
paper filter compartment as required. Do not
use solvents or scourers. Clean the floor nozzle
and the brush holder periodically using the
crevice nozzle.
