Self-Cleaning Filters
Every Pulse-Bac runs Pulse-Bac's patented Automatic Pulse-Clean Technology™. While you work, the vacuum briefly reverses airflow through its filters to knock loose the fine dust that would otherwise cake on and choke suction. There's no air compressor to drag along, no manual shaker, and no stopping the job to clean filters, so suction stays consistent through long grinding and prep runs.
