The 16 gallon vacuum has a 3.0 horsepower two stage motor. This motor uses two vacuum impellers in series which produce moderate suction and high air flow. The motor operates at lower speeds will which result in longer motor life and quieter operation. It sits on four casters and ready for any job. All of the tool accessories ride in the on-board tool storage. Metal extension wands and floor nozzle included with items such as a crevice tool and a claw nozzle. This unit has quality upgrades too! There is a blue Ultra Web cartridge filter (item number 9035000) that is easy to clean and a collector bag (item number 9067300) that fits inside the tank. When you utilize both filters exhaust air is much cleaner so the fine dust and dirt stay in the tank. Included are a metal nozzle and extension wands with other accessories. Shop-Vac
