Filter blowing out of vacuum

Yes it is normal. Most all vacuum cleaners, around 10 amps, will blow out warm to hot air.

The filter is likely clogged and needs replaced.

Hey there! It sounds like your vacuum may be clogged causing it to redirect the air flow which may be causing the cover to blow off. To check the vacuum for clogs disconnect the hose from the cleaner and the wand, use a broom stick to gently loosen and remove any clogs from hose. Also check the wand and the nozzle for blockages. If it is the filter cover that is coming off and there are no clogs, the tabs on the filter cover may be broken. Contact a local service center for information on replacing the filter cover. Reference part 59135033. Or you may contact Hoover Customer Service at 1-800-944-9200. Hope this helps!

Are you sure that you are correctly connecting the filter, and flipping the tabs to "lock" it into the "closed" position.

My Dyson DC25 keeps blowing off the filter within the ball. It then stops the ball from rotating freely.
