The Hoover Air Cordless (http://aircordless.hoover.com) offers up to 50-minutes of runtime from two Extended Runtime LithiumLife Batteries. After hearing from Cordless owners that they wanted a way to keep the second battery on-board while cleaning, we developed this snap on mount. The battery mount attaches to the upper portion of the cleaning wand. It can be oriented forward while cleaning (see photo), but we've found it works best to orient the mount so that it faces backwards. Print will require supports.
