The Shop Vac Shop Sweep series vacuums are made for dry pickup only. These machines are efficient and labor cost saving, made for building maintenance, factories and machine shops, parking areas and sidewalks, warehouses, store fronts, dock areas and malls. The Shop Sweep series currently includes two models, the Industrial Push Sweeper and the Industrial Indoor/Outdoor Vac. Note that the indoor/outdoor vac’s filtration is designed for large materials such as saw dust, leaves and small sticks; it is not meant for fine dust pickup.
