The Billy Goat 33-inch QUIETVAC (QV) is a quiet hard-surface vacuum that features cyclonic filtration, along with electrostatic dust sock technology. This captures sub-micron dust particles as small as 0.1 micron for optimum operator protection. The QV cleans up quietly at 84.5 decibels. QV's self-propelled hydrostatic drive with shift-on-the-fly transmission has infinite forward/reverse speeds. Turf bag holds 36 gallons and loads/unloads with a four-latch bag system. Optional onboard hose expands to 10 feet.
