When to change the dustbag
Change the dustbag when the colored marker in the dustbag change indicator fills the display.
The 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, other accessories can affect the function of the dustbag change indicator.
^Set the suction power selector (if present) to the highest setting and make sure the air inlet valve is closed.
^Hold the wand off the floor and turn on the vacuum claner. If the marker completely fills the indicator window, change the dust bag even if it is not completely full.
How the dustbag change indicator works
The 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 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.
