The GV390 has a 3 motor vacuum head to provide exceptional airflow needed for gutter cleaning, general cleaning, or for collecting high levels of dust. The side port allows for the pickup of larger debris and will provide a cyclone in the tank to reduce clogging. The GP390 can be used for wet and dry applications. The 17 gallon tank is built onto a tipping cart for ease of dumping and cleaning with 2 large wheels in the back and 2 casters in the front for ease of transport in rough terrain and easy maneuvering on flat surfaces. The 3 separate vacuum switches can control the airflow for light duty to heavy duty cleaning needs. HEPA Filter, filter protection bag and 25ft of 2in Vacuum Hose included.
