Maintenance and care

When to change the dustbag

Change the dustbag when the colour marker in the dustbag change indicator fills the display, or sooner if it is no longer effective (see possible reasons for this below).

Dustbags are designed for single use only. Do not attempt to re-use them as suction would be reduced.

Checking the dustbag change indicator

￿Attach the standard floorhead to the suction tube. Do not use any of the other floorheads or attachments as they will cause the dustbag change indicator to give a false reading.

￿Switch the vacuum cleaner on and select the highest power setting.

￿Lift the floorhead off the floor a little. If the marker completely fills the dustbag change indicator, you should replace the dustbag with a new one.

How the dustbag change indicator works

The dustbag change indicator is set for normal household dust. Normal household dust would contain a mixture of dust, hair, carpet fluff, 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 will 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. If this happens you must still change the dustbag because suction power will be greatly reduced by blocked pores in the dustbag.

If, on the other hand, you have vacuumed up a large amount of hair and carpet fluff which typically contains a lot of air, the indicator may fail to react even though the bag is full. You should still change it! Both these extremes can occur.
