Top of the line Shop Vac that really gets the job done! Maneuverability It has casters and you can just pull it behind you as you clean! Awesome! Ease of Maintenance Virtually maintenance free - just make sure you remove the air filter ring BEFORE you use it on wet stuff or you will ruin your filter! Suction Performance Absolutely awesome and powerful as all get out. Picks up change, screws, sand, even kitty litter if your cats are messy like mine. Versatility If you can't vacuum it up with this then you shouldn't be vacuuming it in the first place. Design Easy and efficient design. Durability If anything breaks it will be the hose but that can be easily and fairly cheaply replaced.
