Maintenance and care

Exhaust filter change indicator

Some models are equipped with an exhaust filter change indicator (Reset button) which is designed to alert the user when to change the "ActiveAirClean" or "Active HEPA" filter.

The indicator will light 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.

If a SUPER air clean filter, a, is being used, the filter change indicator can be disregarded but should be reset when it does light. The indicator goes out when the reset button is pressed.

You can replace the exhaust filter supplied with the vacuum cleaner with one of the other types of filters (see "Optional accessories").
