View Here : Ridgid Shop Vac Casters
Mini shop vacs must be part of the 1- to 2-gallon shop vacuum class and no bigger than 3 gallons; They typically feature a peak horsepower of less than 3HP and some of them, but not all, are still portable, but do not include casters, given their small size.
• With the vacuum inlet in the drum, this vac will accept dust collection bags making dry cleanup even easier. • 4 Swivel Casters provide easy 360° mobility. • Accessory storage space built into the caster feet and hose storage on the lid allows quick access to all the provided attachments.
