Advance Carpetwin 14 Vacuum S/N: 56704200

The CarpeTwin® 14 and 18 upright carpet vacuums clean a 14 or 18 inch (36 or 46cm) path, shaking loose and drawing out embedded dirt and grit that shorten carpet life. Five-stage filtration on the CarpeTwin keeps dirt and dust under control. It begins with a two-ply 244 cubic inch (4 liter) paper filter/collector bag. (An optional cloth filter/collector bag is available.) The vac motor is filter protected so it will last longer. The final filter is a hospital grade filtration media. It protects your indoor air quality by filtering to 0.1 microns and exhausting only clean air.Sound insulation also keeps the CarpeTwin vacs hospital quiet, at only 69 dB A. With a two-motor design, separate motors drive the brush and the vacuum. The brush motor has electronic overcurrent protection, and a thermal relief valve protects the vacuum motor. The 5,000 rpm chevron bristle brush is removable, and is motor-driven by a gear belt that won't slip or wear out.
