Provide the utmost in reliability, durability and cleaning effectiveness! The 14-inch 350 MECHANICAL is designed to clean carpets and hard floors, along with superb pet hair removal. To maximize durability, these vacuums are entirely mechanical, instead of electronic. In addition, all electrical components are located in the power head, with none in the bag housing or handle, thereby minimizing electrical connectors and further improving reliability. This also means that the on/off switch is located on the power head, so the user’s foot can easily activate it. Plus, the power cord is externally located, which allows instant, tool-free removal and replacement. All this, along with simple access to most machine parts, means that maintenance is quick and easy.
