Abstract

The present invention is designed to clean the filters during operations without interrupting or having to stop normal use of the vacuum cleaning systems (10) Preferably, the portable vacuum cleaning system (10) comprises a portable frame (11) having a longitudinal axis, a collection tank ( 13) mounted to the portable frame (1 1 ) for collecting and transporting materials which are vacuumed up, and a self-cleaning filter system (30) mounted to the portable frame ( 1 1 ) The self-cleaning filter systems (30) have at least one filter house (3 1 ), a blower means (25), and a control means (50) for controlling an opening/closing port (46) and a reverse air flow port (47) The control means (50) is designed to cause the reverse airflow port (47) to be open when the outlet port (46) is closed during normal operation for a time interval of not more than a second at least three times per hour
