How to clean my Philips bagless vacuum cleaner's filter
The motor protection filter can be cleaned by shaking the dust out of the filter over a dustbin.
Do not use water to clean the motor protection filter.
Clean the motor protection filter every time you clean the filter cylinder.
As the location of the motor protection filter can differ per vacuum cleaner, check your appliance as to where it is located. It can be placed behind the dust container, next to the dust container or in the shape of a round disc.
