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
intended to be used only once. Do
not attempt to re-use as suction
would be reduced by the blocked
pores.
Checking the dustbag change
indicator
^ Raise the vacuum cleaner into the
vertical position.
^ Switch on the vacuum cleaner using
the On/Off control on the handle, and
select the highest power setting.
^ Tilt the cleaner until you can see the
colour marker in the dustbag change
indicator easily. The front of the
Electrobrush will lift up as you do this.
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.
