Abstract
A vacuum extension kit elements includes extensions, a flexible hose and an adapter or two, each having plural diameter male and female connectors for connection to different size vacuum cleaner elements and attachments and/or an elastic adapter. The conduit through the elements is essentially a uniform diameter, for uninterrupted flow, and is small enough to double the flow velocity through standard vacuum cleaner elements. A clog preventer, for filtering out large particles, and inserts, for optional further reduction of female connector inside diameters, are also provided.
