Finding the model number
Check the plate before you buy anything: a Vax name on the box can cover more than one version. Vax puts the rating label on a white or silver sticker on the back of the machine or underneath it. The model number is a mix of letters and numbers such as U84-AL-Pe or UCA1GEV1, and the serial number is 21 digits long.

When to change them
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.
You'll know the battery's going when a full charge stops lasting a whole clean. It happens slowly and creeps up on you.
Cutting out early isn't always the battery. A blocked filter or wand can do the same, and clearing it costs nothing.
