How to clean or replace the filters
General advice
• Remove and clean the Pre-filter and the Rota
filter at least every two months.
• Remove and replace the Hepa filters as soon
as the colour of their undersides corresponds to
the darkest grey on the “Filter full” indicator.
• Check the filters right away if the appliance
becomes noisier. Clean and/or replace the
filters if necessary.
It may be necessary to clean the filters more
frequently. This depends on:
• How much the appliance has been used
(operation time, speed).
• The condition of the air to be filtered.
Removing the filters
- Set the speed selector to position O (fig. 9).
- Remove the mains plug from the wall socket.
- Remove the front cover (fig. 10).
- Remove the Hepa filters (fig. 11).
- Turn the Hepa filters.
- Compare the colour of their undersides with
the colours on the “Filter full” indicator (fig. 12).
- Replace the Hepa filters as soon as the colour
of their undersides corresponds to the darkest
grey on the “Filter full” indicator (fig. 13).
- Remove the Pre-filter (fig. 14).

To place the filters back reverse this process.
