However, if the cleaner has been used
to vacuum up fine dust, such as
plaster, brick dust, cement or flour, the
pores of the dustbag will become
blocked very quickly. This affects the
air permeability of the bag, and the
marker will indicate that the bag is "full"
even when it is not. If this happens you
must still change the dustbag because
suction power will be greatly reduced
by blocked pores in the dustbag.
If, on the other hand, a large amount of
hair and carpet fluff which typically
contains a lot of air is vacuumed up, the
indicator may fail to react even though
the bag is full. You should still change
it. Both these extremes can occur.
How to replace the dustbag (dia. 29 +
30)
^ Press the release catch for the dust
compartment lid and raise the lid as
far as it will go (dia. 11).
The dustbag has a closing flap which
closes automatically when the dust
compartment lid is raised to prevent
any dust escaping.
^ Pull the dustbag out by the grip on
the collar.
^ Fit the new dustbag into the holder as
far as it will go. Leave it folded up
when you take it out of the box.
^ It should be unfolded as far as
possible in the dust compartment.
^ Close the dust compartment lid
securely, making sure it clicks into
position. Take care not to trap the
dustbag when doing so.
The lid will not close without a
dustbag in place. Do not force it!
When to change the dust
compartment filter (for motor
protection)
Replace this filter every time you start a
new packet of dustbags. A dust
compartment filter is supplied with
every packet of Miele dustbags.
How to change the dust
compartment filter (dia. 31)
^ Open the dust compartment lid.
^ Unclip the filter frame and replace
the dust compartment filter.
^ Close the filter frame.
^ Close the dust compartment lid.
When to replace the exhaust filter
Depending on the model, your vacuum
cleaner will be fitted as standard with
one of the following exhaust filters (dia.
10):
a AirClean
Replace this filter every time you start a
new packet of Miele dustbags. An
AirClean exhaust filter is supplied with
every packet of Miele dustbags.
b Active AirClean 30 (black)
c HEPA AirClean 30 (white)
Replace this filter if the exhaust filter
change indicator is completely red (dia.
15).
This occurs after approx. 50 hours of
operation which is equivalent to about a
year of average use. The vacuum
cleaner can still be used. However, the
suction power will be reduced as will
the effectiveness of the filter if it is not
replaced in good time.
