Abstract
A flexible accessory tool for a vacuum appliance is described, comprising an elongated body with a body portion having an attachment end, a nozzle end spaced apart from the attachment end and having an opening formed therein, and a flexible intermediate region for imparting flexibility to the accessory tool during use. The flexible intermediate region is made up of a rigid skeleton portion having a one or more ribs and support struts, over which a layer of non air-permeable flexible material is applied. During use, the flexible accessory tool may be bent to extreme angles in order to reach and clean debris from hard to reach areas, while not suffering from a decrease in vacuum air flow through the tool as it flexes.
