摘要： An air re-circulating vacuum for cleaning loose fabric and other non-tensioned surfaces is disclosed. The vacuum has an air intake and an air exhaust located together inside an air space to create a turbulent flow to pull air and debris through an air flow space as the air flow space is pulled over the surface to be cleaned. The vacuum can be battery powered, or powered by plugging into a standard household current.
摘要翻译： 公开了用于清洁松散织物和其它未张紧表面的空气再循环真空。 真空具有进气口和空气排放物，其一起位于空气空间内，以产生湍流，以在空气流动空间被拉过要清洁的表面时将空气和碎屑通过空气流动空间拉动。 真空可以是电池供电的，或者通过插入标准家用电流来实现。
