Cleaning and care

Emptying the dust container

Fig. 

22

In order to achieve the best possible vacuuming re -
sults, the dust container should be emptied after ever y 
use or, at the latest, when dust in the dust container 
has reached the marking at any point.

!

 Caution

   The dust container can only be removed when the 

appliance is in a horizontal position. Therefore, 
place the appliance on the floor to unlock the re -
lease button.

a) 

 Press the release button and pull the dust container 
out of the appliance using the handle.

b) 

 Remove the lid from the dust container and empty 
the dust container. 

c) 

 Put the lid back on the dust container.

d) 

 Remove any dir t which may have been lodged under-
neath the container ejector opening.

e) 

 Inser t the dust container in the appliance, so that it 
'clicks' audibly into place.

Maintaining the dust separation system

Your appliance is equipped with a Sensor Control indi-
cator. This function constantly monitors whether your 
vacuum cleaner is working at its optimum power level.

 If they are ver y dir ty, the foam filter and filter car t-
ridge should be cleaned under running water.  
Alternatively, the unit can be cleaned in the 
washing machine at ma x. 3 0 °C using a gentle pro -
gramme and the lowest spin speed.  

TIP:

  To protect other laundr y items, put the filter 

unit into a laundr y bag.

d) 

Allow the foam filter and filter car tridge to dr y com-
pletely (at least 24 hours) and then reinser t the foam 
filter into the filter car tridge.

indicator.

Exhaust filter care

Depending on the model, your appliance is equipped 
with either a (H)EPA filter 

Fig.

27

 or a micro filter 

Fig.

29

.
Depending on the model, your appliance has additional 
sound insulation behind the (H)EPA or micro filter. This 
does not have to be cleaned.

(H)EPA filter

You can determine with which (H)EPA filter your appli-
ance is equipped by looking at the imprint on the filter 
frame next to the reference number:

‡

"washable"

 –  the filter can be washed.

‡

No additional imprint 

– the filter must be replaced.
