Finding the model number
Check the plate before you buy anything: a Miele name on the box can cover more than one version. The data (rating) plate with the model and type code is on the underside of the vacuum cleaner. Quote the model type from it when ordering bags or filters.

When to change them
Don't judge a bag by how full it looks. Fine dust clogs the paper or fleece long before it's packed, and suction drops off with it. Trust the indicator over your eyes.
If the indicator says full with a nearly empty bag, look for a blockage in the hose or floorhead before you swap it.
Only rinse a filter the maker says is washable, and let it dry right through before it goes back in. Most of the "it smells" complaints start with a damp filter.
