When to change the filter bag
Change the filter bag when the colored
marker in the filter bag change
indicator is completely red.
Miele dust bags are disposable.
Dispose of full filter bags. Do not
attempt to reuse.
Blocked pores reduce the suction of
the vacuum cleaner.
Checking the filter bag change
indicator
^
Attach the rug and floor tool to the
vacuum cleaner. Other attachments
can affect the function of the filter
bag change indicator.
^ Turn the vacuum cleaner on and
select the highest power setting.
^ Lift the floor brush slightly off the
floor. If the marker completely fills
the indicator window, the filter bag
needs to be changed.
How the filter bag change indicator
works
The filter bag change indicator is
designed to show when the bag is full
of common household dust and
measures the amount of air flow
through the filter bag. Normal
household dust is a mixture of dust,
hair, carpet fluff, threads, sand, etc.
However, if fine dust, such as drill dust,
sand, plaster or flour is vacuumed, the
pores of the filter bag may become
blocked. The marker will indicate that
the bag is "full" even when it is not. The
filter bag should be changed as the
suction power is greatly reduced.
If the bag is bulging with pet fur, hair,
carpet fluff, etc. the indicator may not
register "full". This is because the air
flow of the filter bag may still be high
enough not to activate the marker to
show maximum. The filter bag should
still be changed.
