When to change the dustbag (dia. 26)
Change the dustbag when the colour
marker in the dustbag change indicator
turns red, or sooner if it is no longer
effective (see possible reasons for this
below).
Miele dustbags are disposable and
designed for single use only.
Dispose of the dustbag when full.
Do not attempt to reuse. Blocked
pores in used dustbags will reduce
the suction power of the vacuum
cleaner.
To check the dustbag change
indicator
^ Attach the standard floorhead to the
suction tube.
^ Switch the vacuum cleaner on and
select the highest power setting.
^ Lift the floorhead off the floor a little.
How the dustbag change indicator
works
The dustbag change indicator is set for
normal household dust. This generally
contains a mixture of dust, hair,
threads, carpet fluff, grit etc.
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. 27 +
28)
^ Lift the release catch for the dust
compartment lid and raise the lid as
far as it will go (dia. 10).
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 blue
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.
