I have an AEG smart 485.
At the supermarket I could not find a filter bag with the name of my vacuum cleaner on it. So I picked just one that works for other machines of the same brand: the Swirl PH86.
Later I discovered, that the swirl homepage suggests the Y204 filter bag.
Before opening the package I wonder:
Is there a chance that the PH86 will work anyway?
Is there a danger involved in using the wrong bag?
chances are it wont fit
As long as the bag can inflate to the inside of the compartment, it should work fine. If the bag is too small, then it may pop off the slip-on connector and then fill the compartment with dust.
