Dustbag change indicator
This indicator shows when the dustbag
needs to be changed.
Only test with the rug and floor tool,
since other accessories can affect
the function of the dustbag change
indicator.
^
Set the suction power selector (if
present) to the highest setting and
close the air inlet valve.
^
Lift the rug and floor tool off the floor.
^ The dustbag should be changed if
the red marker completely fills the
indicator window, even if the dustbag
is not completely full.
The indicator measures the airflow
through the dustbag.
Vacuuming up even a small bit of fine
dust such as flour, ash or powder can
cause enough of a drop in airflow to
cause a "full bag" indication, even
though the dustbag appears almost
empty. In this instance the dustbag
must be changed as suction power is
reduced when the pores of the dustbag
are blocked.
On the other hand, the bag may be
bulging with carpet lint or pet fur yet the
suction power may still be high enough.
The dustbag should be changed.
Either of these extremes can occur
during normal use. The dustbag
change indicator is designed for a
mixture of carpet lint, pet fur, hair, sand,
etc. vacuumed during normal
household cleaning.
We recommend
1. If you vacuum a lot of fine dust or
sand:
^ Change the dustbag as soon as the
red marker fills the indicator window,
even if the bag is not full.
2. If you vacuum a lot of hair, pet fur or
loose carpet lint, the indicator will
show only reduced suction when in
fact the bag is full.
^
Change the dustbag as soon as it
physically full, even if the dustbag
change indicator shows that it is not.
