The SmartSensor continuously monitors the airflow throughout the vacuum to ensure an outstanding level of cleaning performance — and helps keep maintenance to a minimum. If filters start to become clogged the SmartSensor responds by either initiating an automatic self-cleaning process or by indicating with a red light that the filter needs cleaning manually. There are no follow-up costs as the high-tech filter materials last as long as the vacuum and there is no need to buy replacement dust bags.*
