When to change the dustbag
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 to be used only once.
Dispose of the dustbag when it is
full. Do not attempt to reuse them as
suction would be reduced.
Checking the dustbag change
indicator
^ Attach the standard floorhead to the
suction tube. Do not use any of the
other floorheads or attachments as
they will cause the dustbag change
indicator to give a false reading.
^ Switch on the vacuum cleaner using
the On/Off foot control s, and select
the highest power setting.
^
Lift the floorhead off the floor a little. If
the marker completely fills the
dustbag change indicator, you
should replace the dustbag with a
new one.
How the dustbag change indicator
works
The dustbag change indicator is set for
normal household dust. This generally
contains a mixture of dust, hair, carpet
fluff, threads, 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, you have
vacuumed up a large amount of hair
and carpet fluff which typically contains
a lot of air, the indicator may fail to
react even though the bag is full. You
should still change it! Both these
extremes can occur.
