The WOC Chief Special Edition has incredible power and vacuum thanks to a more powerful engine by Honda and larger blower. Like the Warrior, the Chief is a simple, dependable machine, that saves you money with no proprietary parts, and easy maintenance. The primary difference is on water damage jobs and large commercial projects where you can take advantage of the additional lift provided by the 4M blower as well as a 100 gallon recovery tank. The additional lift helps maintain plenty of vacuum out to 600 feet.
