Maintenance and care
Exhaust filter change indicator
Some models are equipped with an exhaust filter change indicator (Reset button 7) which is designed to alert when to change the "ACTIVE air clean" or "ACTIVE HEPA" filter.
The indicator lights up after about 50 hours of operation, which is equivalent to about a year of average use. The vacuum cleaner can still be used with the exhaust filter indicator lit. However, the suction power will be reduced as will the effectiveness of the filter if it is not replaced.
Note: If a "SUPER air clean" filter (a) is being used, the filter change indicator can be disregarded but should be reset. The indicator goes out when the Reset button is pressed.
