Cause and remedy
The dust container is full.
Empty and clean the dust container (see "Mainten-
ance").
The Electrobrush is dirty/blocked.
Clean the Electrobrush (see "Maintenance –
Cleaning the Electrobrush" and "Removing the
roller brush from the Electrobrush").
The fine dust filter/pre-filter is soiled.
Run the interim cleaning function for the fine dust
filter (see "Maintenance – Activating the Comfort-
Clean function").
Clean both filters thoroughly (see "Maintenance –
Cleaning the pre-filter and fine dust filter").
The fine dust filter is worn.
Insert a new fine dust filter (HX FSF-2).
The roller brush that has been fitted is not the ideal
choice for the type of flooring.
Select a lower power level (see "Use – Selecting
the suction power level").
Insert the grey Carpet Care roller brush (see "Us-
ing the accessories supplied – Carpet Care roller
brush").
The roller brush is dirty.
Clean the roller brush (see "Maintenance – Clean-
ing the Electrobrush" and "Removing the roller
brush from the Electrobrush").
The Electrobrush power consumption is automatic-
ally set to the optimum level based on the type of
flooring and roller brush used.
The noise is not unusual – the vacuum cleaner is
functioning normally.
The Electrobrush is overloaded – this can happen on
surfaces like deep-pile carpet.
Switch the vacuum cleaner off and switch it on
again at a reduced suction power level. Use the
On/Off switch on the Comfort handle to do this.
