Maintenance and care
When to change the dustbag
Change the dustbag when the colored marker in the dustbag change indicator fills the display.
The dustbags are disposable and in- tended to be used only once. Do not attempt to reuse as suction would be reduced.
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 on and select the highest power setting.
^Lift the floor brush off the floor a little. If the marker completely fills the indi- cator 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 and works by measuring the air permeability of the dustbag.
Normal household dust is a mixture of dust, hair, carpet fluff, threads, grit etc.
However, if fine dust, such as plaster, brick dust, cement or flour is vacuumed the pores of the dustbag will 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 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.
