Filter care

Caution!
The filter can only be cleaned if
the appliance is switched off.
Your appliance is equipped with a
"Sensor Control" function.
This function constantly monitors
whether your vacuum cleaner is
working at its optimum power
level. The indicator light lets you
know when you need to clean the
filter cartridge, so that the appli-
ance can reach its optimum power
level once more.

The indicator lights up blue or is
off when the appliance is working
at its optimum level. Once the
indicator turns red and flashes,
the outer filter unit and filter car-
tridge must be cleaned.
The appliance is automatically
adjusted to power level 1.
