Changing the dust bag and filters

Replacing the dust bag

Figure 

If the dust bag change indicator lights up brightly and 
evenly when the floor tool is lifted from the carpet and 
the highest suction power is selected, the dust bag must 
be changed, even though it may not yet be full. In this 
case it is essential to change the dust bag due to the 
type of material it contains.
First check that the nozzle, suction pipe and flexible hose
are not blocked, as this would also lead to the dust bag
change indicator being triggered.
