When to change the dustbag (dia. 29)
Change the dustbag when the colour
marker in the dustbag change indicator
fills the display, 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 it is
full. Do not attempt to reuse as
suction would be reduced.
Checking the dustbag change
indicator
^ Attach the standard floorhead to the
suction tube.
^ Switch the vacuum cleaner on and
select the maximum power setting.
^ Lift the floorhead off the floor a little.
How the dustbag change indicator
works
The indicator is set for normal
household dust. This generally contains
a mixture of household dust made up
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
the 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. 30,
31 + 32)
^ Press the release button for the dust
compartment lid and raise the lid as
far as it will go.
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 next
to the self-closing flap 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.
Warning: The lid will not close
without a dustbag in place. Do not
use force.
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.
