How the dustbag change indicator
works
The dustbag change indicator is
designed to measure the air
permeability of a dustbag containing
common household dust. Normal
household dust would contain a mixture
of dust, hair, carpet fibre, threads, grit
etc.
However, if the vacuum cleaner has
been used to suck up fine dust, such
as plaster, brick dust, cement or flour,
the pores of the dustbag 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.

You should change the dustbag if the
marker indicates that the bag is "full"
even when it is not.
If, on the other hand, you have
vacuumed up a lot of hair and carpet
fibre (which typically contains a lot of
air) the indicator may fail to react or
may show that it is 1/2 full even though
the bag is full. You should still change
the bag.
