The Karcher NT 30/1 Tact Te HEPA Wet/Dry Vacuum (1.148-216.0) is a favorite among craftsmen for wet and dry vacuum cleaners. It is an ideal fit for a workshop or construction site and can expertly remove fine dust where other vacuums may fail. It features the Tact automatic filter cleaning system which provides improved performance with a reduced noise level, even after vacuuming large amounts of fine dust the Tact system continues to provide powerful suction without the need for manual cleaning. Karcher's newly developed rotary switch and infinitely variable speed control are two more features that help this vacuum to rise above the competition.
