Advance’s 15 and 18 inch Spectrum dual-motor upright vacuums deliver the superior performance results expected from Advance vacuums: dirt pickup and filtration. Upright vacuums rely on a combination of dirt pickup to remove soil from carpets and filtration to ensure that dust and other airborne particles stay captured. With the addition of a brush motor, the Spectrum dual-motor vacuum has a total of 1,350 watts of power. Operators now have single pass power in an upright vacuum, which results in greater productivity.
