When to change the dustbag
Change the dustbag when the colored
marker in the dustbag change indicator
fills the display.
Miele dust bags are disposable and
made to be used only once. Do not
attempt to reuse.
Checking the dustbag change
indicator
^ Attach the floor tool to the vacuum
cleaner. Perform this test with the
floor tool only, since other
attachments can affect the function of
the dustbag 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 dust bag needs
to be changed.
How the dustbag change indicator
works
The dustbag change indicator is
designed to show when the bag is full
of common household dust and
measures the amount of air flow
through the dustbag. 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 dustbag may become
blocked. The marker will indicate that
the bag is "full" even when it is not. The
dustbag 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 dustbag may still be high
enough not to activate the marker to
show maximum. The dustbag should
still be changed.
