1) Clean the motor protection filter every time you replace the disposable dust bag or empty the reusable dust bag. The motor protection filter holder is located behind the dust bag. Remove the dust bag holder with the dust bag to get access to the motor protection filter. Take the filter out of the vacuum cleaner and shake the filter over a dustbin to clean it. Never use the appliance without the motor protection filter. This could damage the motor and shorten the life of the appliance.
2) If the exhaust filter is dirty, remove it and replace it with a new exhaust filter. You will find the exhaust filter on the back of the appliance behind a removable grille.
Some vacuum cleaners come with a washable exhaust filter. To make sure that you have a washable exhaust filter, check the filter frame. If it does not say 'washable' on the frame, look at the type plate of the appliance to find the type number. A washable filter has to be replaced after it has been cleaned under the tap four times or after two years of use.
Important: Never clean the filter with a brush.
Important: The filter cannot be cleaned in a dishwasher
Important: Make sure the filter is completely dry when you put it back into the appliance
a. To clean the filter, take it out of the appliance. Rinse the pleated side of the filter under a slow-running hot tap. Hold the filter in such a way that the pleated side points upwards and the water flows parallel to the pleats. Hold the filter at an angle so that the water washes away the dirt inside the pleats.
b. Turn the filter 180° and let the water flow along the pleats in the opposite direction.
c. Carefully shake the water from the surface of the filter. Let the filter dry at least 2 hours before you put it back into the vacuum cleaner.
Note: Cleaning does not restore the original colour of the filter, but does restore its filtration power.
Note: To guarantee optimal dust retention and performance of the vacuum cleaner, always replace the exhaust filter with an original Philips filter.
3) Replace the dust bag as soon as the dust bag-full indicator (see the figure for an example) has changed colour permanently, i.e. even when the nozzle is not placed on the floor.
