The Panasonic JetForce Bagless Vacuums all feature JetForce technology, which uses a unique Hour Glass shaped dust container to capture dirt. The process is so effective that JetForce models experience no loss of suction. The three Panasonic JetForce vacuums have an hourglass shape that forces large debris towards the bottom of the cup, keeping it away from the filter. In most vacuums without this design, the dust can more easily clog the filter, reducing suction power and requiring more filter maintenance. In addition to the hourglass shape, the Panasonic JetForce vacuums include nine cylinders for multi-cyclonic dirt separation, which also helps to create cleaner exhaust air. For homes with pets, the Panasonic JetForce includes the Air Turbine brush, a pet hair attachment that is ideal for removing stubborn pet hair from furniture and carpets. The Panasonic JetForce also includes a HEPA Media Filter, which captures small particles such as allergens, irritants and pollutants.
