Finding the model number
It's worth a look at the rating plate first, because names get reused across generations. Label on the back of the machine (Numatic).
When to change them
Bags and the TriTex filter are for dry vacuuming only; remove them for wet pick-up. Change the bag when suction drops or the machine feels heavy; the filter is not washable. (source)
A bag that's only half full can still be done for: fine dust blocks the pores first, which is why the indicator can go red early after a lot of plaster or fireplace dust.
Seeing a full warning on a fresh bag usually points to a blockage in the hose or floorhead. Check there before blaming the bag.
Washable filters go back in bone dry or not at all. A damp one smells, and on some machines it can let the motor pull moisture through.
