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
intended to be used only once. Do
not attempt to reuse.
Checking the dustbag change
indicator
^
Attach the floor brush to the vacuum
cleaner. Only test with the floor brush,
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 off the floor a little.
If the marker completely fills the
indicator window, then the bag needs
to be changed.
How the dustbag change indicator
works
The indicator is designed to show when
the bag is full of common household
dust and works by measuring the air
permeability of 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 become blocked.
The marker will indicate that the bag is
"full" even when it is not. In this instance
the dustbag must be changed as
suction power is reduced when the
pores of the dustbag are blocked.
If, on the other hand, a large quantity of
hair, wool or carpet fluff is vacuumed,
the dustbag change indicator may not
register "full" even though the bag is
full. This is because the air permeability
of the dustbag may still be high enough
not to activate the marker to show
maximum. The dustbag should still be
changed.
